The commercial service lives of bus batteries are significantly extended and natural resources
are conserved. That is the result of a new cooperation between Volvo Buses and Stena
Recycling subsidiary Batteryloop. After the batteries are removed from Volvo’s buses, they
are reused as energy storage units for a number of years, for instance in buildings and
charging stations.
“Volvo Buses is one of the pioneers in electromobility which provides clean, quiet and efficient public
transport. We have a clear-cut sustainability strategy at every single stage of our value chain, and we
are now taking yet another step forward through planned, consistent reuse of bus batteries. In our
electromobility operation we are thus creating a new circular business cycle and this cooperation is
truly a major step in the right direction,” says Håkan Agnevall, President of Volvo Buses.
Bus batteries are used for many years in regular traffic before they need to be replaced. However,
when new batteries are fitted to the vehicle, the old ones still have considerable capacity left to offer.
This capacity is too limited to efficiently propel a bus, but it is more than sufficient for static use for
energy storage purposes. Repurposing the batteries means that natural resources can be conserved
since it is not necessary to use new batteries for energy storage.
“We are delighted and proud that Batteryloop has the opportunity to buy the used batteries and
develop this solution together with Volvo Buses. In addition to reuse, under the agreement we also
guarantee safe and environmentally suitable recycling when the batteries come to the end of their
second life as energy storage units. We thus offer a sustainable circular solution for Volvo Buses
batteries. What is more, this cooperation means we can convert a cost into a source of revenue for
the customer,” says Rasmus Bergström, President of Batteryloop.
The new recently signed agreement has a global reach. It covers all the batteries for which Volvo
Buses is responsible in its electric buses the world over. To date most of these buses are to be found
in Europe, but the number of electrified buses is expected to increase in other parts of the world too.
“We see a steadily increasing demand for electric buses from cities all over the world, and since we
entered the electric bus market early, the numbers of used batteries are set to increase,” explains
Håkan Agnevall.
The demand for local energy storage units is expected to increase in the future. Not least, an energy
storage unit offers new scope for storing renewable energy, which can be used to meet peaks in
electricity demand. Any surplus can be sold, delivered straight into the grid.
“An energy storage unit is like a large power bank that gives the user considerable flexibility and can
help generate income. We see that there is a fast-growing market in different kinds of properties, and
also for charging stations for electric vehicles both in industry and in society. Our cooperation with
Volvo Buses will provide a valuable contribution to development of the infrastructure that needs to be
built up,” comments Rasmus Bergström.

General Motors Co recently shared the details of its future strategy to grow the company’s electric vehicle (EV) sales quickly, efficiently and profitably at a gathering that was attended by hundreds of its employees, dealers, investors, analysts, media and policymakers.

Speaking at the event, Mary Barra, GM chairman and CEO said that the GM team accepted the challenge to transform product development and position the company for an all-electric future. The automotive manufacturer came up with a multi-brand, multi-segment EV strategy that offers economies of scale which could rival its full-size truck business while offering even more flexibility and less complexity.

The core of GM’s strategy is a modular propulsion system and a highly flexible, third- generation global EV platform that is powered by proprietary Ultium batteries. The system and the platform will make it possible for the company to compete for almost every customer in the market today, whether they are seeking a luxury experience, affordable transportation, work trucks or a high-performance machine.

GM President Mark Reuss said that thousands of GM scientists, engineers and designers are working on a historic reinvention of the company. He added that they are on the cusp of delivering a profitable EV business that can satisfy millions of customers.

Ultium Batteries and Propulsion System Highlights

• GM says its new Ultium batteries are unique as their large-format, pouch-style cells can be stacked either vertically or horizontally inside the battery pack. Thus, engineers can optimize battery energy storage and layout for the design of each vehicle.
• Ultium energy options range from 50 to 200 kWh, and this could enable a GM-estimated range up to 400 miles or more when the vehicle is fully charged along with quick acceleration from 0 to 60 mph acceleration in just 3 seconds. Motors GM makes in-house will support front-wheel drive, rear-wheel drive, all-wheel drive and performance all-wheel drive applications.
• Ultium-powered EVs are meant for Level 2 and DC fast charging. Most of them will have 400-volt battery packs and up to 200kW fast-charging capability while GM’s truck platform will have 800-volt battery packs and 350 kW fast-charging capability.

GM’s flexible, modular approach to EV development is expected to result in major economies of scale and thus create new revenue opportunities, including:

• Continuous Improvement in Battery Costs: GM’s joint venture with LG Chem will reduce battery cell costs to less than USD 100/kWh. The cells use a proprietary low cobalt chemistry and costs are expected to become even less with ongoing technological and manufacturing breakthroughs.
• Flexibility: GM’s all-new global platform is flexible enough to facilitate the building of a diverse range of trucks, SUVs, crossovers, cars and commercial vehicles. These vehicles will offer the benefits of outstanding design, performance, packaging, range and affordability.
• Capital Efficiency: GM plans to leverage existing property, including land, buildings, tools and production equipment such as body shops and paint shops in order to spend less capital to scale its EV business.
• Complexity Reduction: The vehicle and propulsion systems were designed together to minimize complexity and part counts beyond today’s EVs, which are less complex than conventional vehicles powered by internal combustion engines. For example, GM plans 19 different battery and drive unit configurations initially, compared with 550 internal combustion powertrain combinations available today.
• Rising Customer Acceptance: Third-party forecasters expect U.S. EV volumes to more than double from 2025 to 2030 to about 3 million units on average. GM believes volumes could be materially higher as more EVs are launched in popular segments, charging networks grow and the total cost of ownership to consumers continues to fall.
• New Sources of Revenue: The company hopes to reach beyond its own fleet and license technology to others by vertically integrating the manufacture of battery cells, th.

GM expects the first generation of vehicles made as part of its EV program to be profitable and the initial programs are expected to pave the way for further accretive growth. GM’s technology can be scaled to meet customer demand much higher than the more than 1 million global sales the company expects mid-decade.

Upcoming Launches and Reveals
The brands from GM which will be launching new EVs from this year include Chevrolet, Cadillac, GMC and Buick. The next EV from Chevrolet EV will be a new variant of the Bolt EV, and will make its debut in late 2020. This will be, followed by the 2022 Bolt EUV, that will be launched in the summer of 2021. The Bolt EUV is touted as the first non Cadillac model to feature Super Cruise, which GM says is the the industry’s first true hands-free driving technology for the highway. GM plans to expand the use of this technology to 22 vehicles by 2023, including 10 by next year.

The Cruise Origin which made its public debut in San Francisco in January 2020 is billed as a self-driving, electric shared vehicle. It was the first product that used GM’s third generation EV platform and Ultium batteries. Cadillac’s Lyriq luxury SUV will be launched in April while the Ultium-powered GMC HUMMER EV will be seen on the global stage in May 2020. Production is expected to begin in Fall 2021 at GM’s Detroit-Hamtramck assembly plant, GM’s first assembly plant that will be dedicated fully to the production of EVs.

Through one of its subsidiaries named Shanghai Maple Guorun, Geely Automobile Holdings is joining hands with Korean company, LG Chem to set up a joint venture company. Geely owns 99 percent of Shanghai Maple Guorun and the new joint venture company that the two companies set up will engage in the production of batteries for electric vehicles. LG Chem is one of the leading manufacturers of such batteries in the world.

According to the terms of the agreement, Shanghai Maple Guorun and LG Chem will each have a 50:50 share in the new joint venture company that will specialize in the production and sales of new energy vehicle batteries. The two companies will invest a total amount of USD 188 million in the company and the amount would be split equally between both parties.

Geely Auto became one of the first automotive companies that undertook to electrify its product range through an announcement in November 2015. As part of the Blue Geely Initiative, Geely’s plan is to derive 90 percent of its sales from electrified vehicles from 2020. The term electrified vehicles will cover mild hybrids, plug-in hybrids and pure electric vehicles. The partnership with LG Chem will make it possible for Geely to realize its Blue Geely Initiative as it would ensure a stable supply of core components that could be used in future models tha the company would product to meet the growing demand in the Chinese market for new energy vehicles.

An Conghui, president of Zhejiang Geely Holding Group, CEO and president of Geely Automobile Group, said that Geely Auto has already created a strong supply chain network for the production and development of new energy vehicles. He said that the new joint venture agreement with LG Chem would further reinforce the company’s position as a leader in new energy vehicles and help it to realize its aim of providing its customers with more value and a better ownership experience.

Kim Jong-Hyun, president of LG Chem’s Energy Solution said: “This joint venture with China’s leading privately-owned automotive company, Geely Auto, can be seen as contributing to the progress of China’s overall electric vehicle industry.”

In 2018, China accounted for 62 percent of global EV sales with the new energy vehicle market reaching 1.25 million units in 2018. The automotive market in China is expected to grow at a strong pace in the coming years. In May 2019, Geely Auto sold more than 10,115 electrified vehicles, representing a 25 percent increase in sales over the same period a year earlier.

Geely has continued this performance in the first five months of 2019, with the company selling a total of 41,615 pure electric and electrified vehicles and launching the Geometry brand in April 2019 as a pure electric brand within Geely Auto. Geometry’s first model, Geometry A performed well with regard to sales and over the next two years Geely Auto plans to launch over 30 electrified vehicles including hybrid and pure electric vehicles.

Autoneum has developed textile battery undercovers to help automakers make electric vehicles which are lighter and more environmentally friendly. The undercovers are made of Ultra-Silent, a material that meets the specific requirements for acoustic and thermal management of electric vehicles. Use of these lightweight components will further enhance the driving range of the vehicles and help them to regulate their noise levels as well.

Autoneum offers various multifunctional components such as carpet systems, inner dashes and underbody systems, which have a positive impact on the driving range thanks to their light weight and which are specially tailored to the acoustic and thermal management needs of electric vehicles.

The battery undercovers made of Ultra-Silent (the Company’s new textile underbody technology) essentially perform the role of insulators by minimizing the sound that enters the passenger cabin, for instance, caused by tires, and also pass-by noise. Sound-reducing components are essential for electric models as well as many external and internal components like fans, pumps and electronic drive components are more audible due to the lack of engine noise and thus affect driving comfort. At the same time, the textile battery undercovers are claimed to make the components up to 50 percent lighter than corresponding components made of plastic and thus ensuring a greater driving range.

Undercovers which are made of Ultra-Silent are installed underneath the battery casing, thus providing the battery cells with the highest level of protection against volatility in cooling or heating and ensuring a constant temperature to optimize battery capacity. As an outcome of their use, battery performance improves significantly. Autoneum also claims that these undercovers are also resistant to water, stone chipping and vibrations thus giving added protection to the battery casings. In order to calibrate the temperature resistance and material stiffness of undercovers, Autoneum uses a broad range of internally developed simulation tools. These tools are deployed in both the development phase of new electric models as well as in the further development of those already on sale.

The lightweight components made of Ultra-Silent are mostly fashioned from recycled PET fibers which can be fully reclaimed, thus giving them the environment friendly tag. The company makes its Ultra-Silent components at its factories in Sevelen, Switzerland, Gundernhausen, Germany, Jeffersonville (Indiana), USA, and Pinghu, China. These components are already being used in models of European, US and Chinese automobile manufacturers. From July 2020 onwards, the first battery undercovers will be produced in series at the Gundernhausen plant for the fully-electric model of a leading German car maker.

Daimler has announced that the company will purchase batteries worth 20 billion euros (USD 23 billion) which will power its range of future EVs. Daimler has ambitious plans to launch EVs belonging to both the Mercedes-Benz and Smart brands in addition to commercial vehicles like vans, trucks, and buses.

Daimler’s goal is to offer an electric variant of every Mercedes model by 2022. These electrified models might be mild hybrids, plug-in hybrids, hydrogen fuel cell vehicles or pure battery powered EVs. By the year 2025, Daimler plans to have battery-electric cars account for 15 to 25 percent of its global sales. According to the current timeline, Daimler’s first mass-market battery-powered Mercedes which will be called the EQC Crossover will be available for sale in the US market from 2020. Smart EV are already available on an exclusive basis in the North American market.

Daimler’s commercial vehicle divisions will also push ahead with their electrification strategy. The company has already manufactured small numbers of electrically powered commercial trucks its Fuso, Freightliner, and Mercedes brands. Daimler also plans to launch an electric variant of the Mercedes Sprinter van, and is investing in electric bus manufacturer Proterra. Recently, Daimler’s Thomas Built brand teamed up with Proterra on the prototype of an electric school bus.

All the new electrified vehicles will need batteries and Daimler is planning to source these batteries from third party suppliers with whom it has finalized contracts through 2030. The company did not divulge the names of the suppliers it has signed deals with. Daimler is also conducting research to develop new battery technologies, with the key focus being on methods to reduce the use of materials like cobalt in the battery cells.

Daimler is planning to invest an amount of 1 billion euros ($1.1 billion) in a global network of factories to assemble the battery cells into battery packs that will be installed in vehicles.

BYD has announced that the company is planning to construct a new factory for the production of batteries. The factory which is to be located in the city of Xi’an, the capital of Shaanxi province will have an annual production capacity of 30 GWh once it becomes fully operational. Thanks to its size, this will be one of the “super factories” in China and it will play a key role in BYD’s wider strategy to increase production.

BYD’s new battery factory in Xi’an will require an investment outlay of USD 1.75 billion dollars. This factory will be BYD’s second new battery factory. In August 2018, the electric car manufacturer had signed an agreement with the Chinese city of Chongqing to set up a battery factory costing 1.2 billion euros there that will have an annual capacity of 20 GWh.

These two factories will thus be integral to BYD’s long-term strategy. As part of this strategy, the plan is to ramp up BYD’s annual capacity from the currently expected 28 GWh in 2018 to 48 GWh in 2019 and eventually up to 60 GWh in 2020. Another key player in this sector, CATL is planning to increase its battery cell manufacturing to 88 GWh by 2020.

BYD will be using the batteries made at these two plants not only for its own electric models but will also be supplying these batteries to third parties.

In the case of car manufacturer Changan, the company wanted to participate in the production of batteries along with BYD and this is why they planned to set up a joint venture plant in Chongqing which will produce up to 10 GWh of batteries and will engage both in the sale and recycling of batteries. In view of China’s plans to compel vehicle manufacturers to recycle batteries using the Traceability Management Platform to manage the process, the two companies will perform this task jointly.

Tesla has signed a supply agreement with the biggest producer of lithium in China, Ganfeng Lithium in order to secure lithium for the batteries used in its vehicles.

Ganfeng Lithium had rently signed a massive supply agreement with LG Chem, and announced that it has finalized a new deal to supply lithium-hydroxide to Tesla from this year up to 2020. There is also an option to extend the contract by another 3 years, according to a Bloomberg report.

It is expected that Tesla and Panasonic which manufactures the batteries used by Tesla would be using the lithium obtained from Ganfeng at its Gigafactory 1 in Nevada and not at its upcoming new Gigafactory 3 in China.

Tesla has ambitious plans of achieving 35 GWh of battery cell production at its Gigafactory 1 by the end of the year, and to reach this goal, it is estimated that it will need about 28,000 tons of lithium hydroxide on an annual basis.

Through the new deal with Ganfeng, Tesla will be able to fulfill about 20 per cent of its lithium requirements.

Tesla has been focusing more on its battery supply chain after embarking on its Gigafactory project with Panasonic and has been trying to secure its supply of raw materials from multiple sources. Initially, the emphasis was on sourcing resources locally from the United States, but recent contracts, including the Ganfeng deal have been with companies based overseas. Earlier in 2018, Tesla had finalized an agreement to source lithium from Australia.

Tesla has already signed a conditional supply agreement with Pure Energy Minerals, which has access to 9,500 acres of lithium brine in Clayton Valley. This site is only a four-hour drive from Tesla’s Gigafactory, but Pure Energy Minerals has not entered the production phase. This is why Tesla needs to secure lithium from other sources.

One main reason why it takes a long time for charging an electric car is that the batteries that are used in these vehicles need to be charged slowly. The chemicals used in these batteries are such that if they are charged too quickly too often, they would decay or become unstable very soon. Researchers at Pennsylvania State University in United States have come up with a possible solution to this problem.

When batteries are charged too fast, there is a phenomenon known as dendrite growth as part of which lithium ions are plated onto carbon anodes while charging. This problem is particularly prevalent at low temperatures and that is why it takes more time to charge an electric car at lower temperatures than at higher temperatures. The vehicles also need extra energy to heat the battery when they are being charged in cold weather.

Xiao-Guang Yang, a researcher at Pennsylvania State University has developed a new structure for the battery comprising nickel foils embedded in the cathode. These nickel foils preheat the anode during charging in order to prevent the lithium ions from plating.
Yang presented a research paper in which he stated that cells having his new structure charged for 4,500 cycles with less than 20 percent capacity loss. This is 90 times higher than what is seen in standard cells.

Using this new structure could make it possible to charge batteries in 15 minutes even at temperatures as low as minus-50 degrees Celsius while giving them a life of about 12 years, according to Yang. He said that nickel foils add only 0.5 percent in weight and 0.04 percent to the cost.
Generally, manufacturers compromise temperature for charging time and vice versa, but with Yang’s new breakthrough, such compromises are no longer needed.

A company that is part of the Freudenberg group, Freudenberg Sealing Technologies, has developed an innovative heat shield that can be used to make batteries safer and thus makes electrified vehicles more viable in the long run. This heat shield can be used in prismatic and pouch cells with negligible impact when it comes to the space needed for installation. It comprises a silicone based elastomer that has a high heat resistance. When this is combined with the high insulating properties of air, the heat from a damaged cell remains insulated until it can be drained away.

As an outcome of this innovation, Freudenberg is now working on the achievement of greater range without increasing the size or weight of the battery. Greater energy output calls for higher safety requirements, and the shield is highly useful for the protection of the battery pack, especially in the event of thermal runaway where the temperatures in a cell could soar to 600 degree Celsius. In case the battery’s cooling system does not drain the heat away, this could lead to increase in temperature of neighboring healthy cells and trigger a chain reaction, ultimately causing an explosion.

The heat shield has three main characteristics. The shield itself is made of a heat-resistant material, a silicone-based elastomer. It has a waffle-like structure that slows the heat transfer between the cellsand comprises tiny pockets of air for outstanding heat insulation. The shield is also very thin, with the maximum thickness being just 1 mm. The loss of the existing energy density due to the shield’s use is hardly noticeable.

Freudenberg conducted a series of tests which showed a considerable reduction in temperature on the surface of the battery where the heat shields were placed. Freudenberg expert Peter Kritzer said, “This will adequately protect a neighboring cell against the destruction of cathode material or the separator.”

Freudenberg has also given great thought to the mounting of the heat shield. As the air pockets adhere well to the smooth metallic surface of a prismatic cell due to their suction effect, an individual shield can be positioned precisely.

If these flexible formations were extended over the top of the cell, it could enclose and seal the rupture disc located there. In case of overpressure in the battery cell, the ruptured disc would ensure that the resulting partially toxic gases escape in a controlled way. “Even more than energy density, safety is the most important characteristic of future battery generations in terms of quality,” Kritzer said.

The company will work with Superdielectrics to work on development of batteries using the same material that the startup had initially developed for contact lenses. Rolls-Royce will be contributing its automotive engineering experience to the project while Superdielectric specializes in materials science and is producing new hydrophilic polymers.

The team of scientists at Superdielectrics includes researchers from the University of Bristol and the University of Surrey. Comemnting on the partnership, Dr. Dave Smith, Director of Central Technology at Rolls-Royce said that he believes electrification will play an iincreasingly prominent role in the automotive sector in the coming years and Rolls-Royce is trying to take advantage of new developments in the field by partnering with companies working on potential new technologies for energy storage.

The materials that Superdielectric has developed are similar to those used for contact lenses. These polymers can also be used to increase electricity storage in capacitors. The battery that Superdielectric created has the capability to store more electricity by creating electrostatic fields. Tests indicated that this capacitor can be between 1000 to 10,000 times more efficient than ones that are currently available in the market. Taking advantage of this innovation can make it possible for electric vehicles to charge much faster.

Rolls-Royce executive Warren East told, “Electrification is an inescapable trend in industrial markets today. And that includes in aerospace, in due course, but it’s actually present today in many of the markets that we serve through our power systems business.”
