Tesla’s prototype battery with 5 times more energy storage comes to life at Panasonic

The Japanese company revealed the prototype in an effort to fulfill Tesla’s future battery dreams.

By Sean Szymkowski

Tesla long promised big changes for its future batteries, and Panasonic hopes its latest prototype battery will deliver for the electric carmaker. On Monday, Automotive News reported on the Japanese company’s new prototype battery created specifically for Tesla. It promises fives times more energy storage, which may increase ranges significantly.

In addition to more energy, the battery will cost 50% less to produce and help boost battery production at Panasonic “100-fold,” by 2030, according to the report. These three elements could produce a game-changing battery pack for Tesla with a lower cost and more range at the core of EV adoption hurdles. Panasonic did not immediately return a request for comment and more information on the prototype battery. Tesla does not operate a public relations department to field requests for comment.

3D-printed solid-state batteries near production

Batteries that are lighter, cheaper and easier to produce could result from a convergence of modern approaches

By Freddie Holmes

A company that plans to produce 3D-printed solid-state batteries is readying to launch its first pilot line. California-based Sakuu is targeting not only electric vehicles (EVs) but also other sectors such as aerospace, consumer electronics and medical devices. The new battery line is expected to be operational by the end of 2021 and will have a capacity of up to 2.5 megawatt hours (MWh) per year.

Once up and running, the plan is to begin issuing batteries to strategic customers and ‘early access partners’ who can perform their own development and testing. One other solid-state battery start-up QuantumScape recently ran a similar initiative, where its pouch cells were issued to third parties. The results were presented in Decemberalongside its joint venture partner, Volkswagen Group.

BMW Proposes to Use Old Batteries in Off-Grid Solar Charging Stations

by Gustavo Henrique Ruffo

The three “Rs” for a more sustainable life are Reduce, Reuse, and Recycle. BMW created a project in Brazil that used the first two Rs to prevent the third one. After collecting used battery modules from some i3s it sold in that country, the company joined UFSC (Federal University of Santa Catarina), Grupo Solvi, and Energy Source to create an off-grid solar charging station. 9 photos

The solution comprises eight solar panels on the roof of the charging station. They feed a tower with six battery modules from the i3 which are no longer good enough for automotive use but are perfectly fine for storing the energy generated by these solar panels. An inverter manages these modules. It controls both the energy stored and charging electric vehicles that connect to the charging tower thanks to a BMW Wallbox charger.

Batteries made from trees could help transform the future of electric travel

Finnish sustainable material developers have opened a mill that turns powdered tree macromolecules into energy   



By Shannon McDonagh 

A material found in the wood of our plants is being trialled as a way to produce sustainable battery power.

Finnish designers Stora Enso have built a new production facility costing €10 million that will create renewable bio-based carbon by turning trees into batteries. This will be achieved by the use of a wood-based material called lignin.

The plant is based beside the company’s Sunila Mill in Kotka, southern Finland, which employs over 150 people and specialises in producing softwood pulp, and biofuels like tall oil and turpentine.

The company is responsible for developing a number of wood and biomaterial-based solutions for everyday problems that require eco-friendly solutions. Their innovative product offerings range from mouldable woods to formed fiber food packaging.

Hyundai and UL ally to give EV batteries a second life

The two agreed to advance safe deployment and use of second-life battery energy storage systems.

Underwriters Laboratories, a U.S. standards development organization, and Koren car manufacturer Hyundai Motor Co. signed a memorandum of understanding to help further the safe deployment and use of second-life battery energy storage systems (SLBESS). 

The two said they will collaborate on SLBESS initiatives, including safety testing and assessment, a North America product demonstration project, and evaluation process development. They said they intend to use their worldwide presence to further SLBESS market adoption.

Second-life batteries often consist of electric vehicle batteries that no longer meet the requirements of automotive applications, but are still worthwhile additions as grid-connected energy storage devices.

We may be on the brink of a new paradigm for nuclear power, a group of nuclear specialists suggested recently in The Bridge, the journal of the National Academy of Engineering. Much as large, expensive, and centralized computers gave way to the widely distributed PCs of today, a new generation of relatively tiny and inexpensive factory-built reactors, designed for autonomous plug-and-play operation similar to plugging in an oversized battery, is on the horizon, they say.

‘HOLY GRAIL’ BATTERY BREAKTHROUGH SEES SCIENTISTS SOLVE 40-YEAR PROBLEM

Lithium-metal batteries hold far more energy and charge in a fraction of the time compared to those used in smartphones and electric cars

By Anthony Cuthbertson

Researchers have demonstrated a solution to a 40-year problem regarding the creation of a “holy grail” battery that could radically transform the electric car industry.

The breakthrough involves harnessing the power of lithium-metal batteries, which are capable of holding substantially more energy and charge in a fraction of the time compared to lithium-ion batteries that are currently used in everything from smartphones to Tesla vehicles.

Until now, scientists have been unable to create a lithium-metal battery stable enough to be used in commercial applications.

The development, made by a team at Harvard University’s School of Engineering and Applied Science (SEAS), allows this next-generation batter to be charged and discharge at least 10,000 times, which would increase the lifetime of electric vehicles to that of of their gasoline counterparts – while simultaneously increasing their range and reducing their charge time.

“A lithium-metal battery is considered the holy grail for battery chemistry because of its high capacity and energy density,” said Xin Li, an associate professor at SEAS.

The Battery That Will Finally Unlock Massless Energy Storage

It could revolutionize electric vehicles and aircraft.

By Caroline Delbert 

  • Scientists have made a massless structural battery 10 times better than before.
  • The battery cell performs well in structural and energy tests, with planned further improvements.
  • Structural batteries reduce weight and could revolutionize electric cars and planes.

In groundbreaking new research, scientists have made a structural battery 10 times better than in any previous experiment. 

What’s a structural battery, and why is it such a big deal? The term refers to an energy storage device that can also bear weight as part of a structure—like if the studs in your home were all batteries, or if an electric fence also held up a wall.

In the new paper, researchers from Chalmers University of Technology and KTH Royal Institute of Technology in Sweden reveal how their “massless” structural battery works.RELATED STORYIs the World Ready for the EV Battery Boom?

The main use case is for electric cars, where a literally massive amount of batteries take up a ton of room and don’t contribute to the actual structure of the car. In fact, these cars must be specially designed to carry the mass of the batteries. But what if the frame of the car could hold energy? “Due to their multifunctionality, structural battery composites are often referred to as ‘massless energy storage’ and have the potential to revolutionize the future design of electric vehicles and devices,” the researchers explain.

NREL looks at barriers to lithium-ion battery recycling and sees opportunities

The analysts assessed the current state of reuse and recycling of large-format lithium-ion batteries used in EVs and battery energy storage and found there is plenty of room for improvement.

By  DAVID WAGMAN

Recycling lithium-ion batteries could create a new market for U.S. companies, an NREL report said.

Researchers at the National Renewable Energy Laboratory (NREL) released a report detailing the technological, market, and regulatory hurdles to creating a circular economy for lithium-ion batteries.

The battery technology is increasingly in demand for energy storage and use in electric vehicles (EVs). But its current lifecycle is almost entirely one-way, from manufacture to consumption to disposal, with little thought given to reuse or recycling. Only one U.S. lithium-ion battery recycling facility exists today, the analysts said.

To start to rethink the one-way lifecycle, the NREL team assessed the current state of reuse and recycling of large-format lithium-ion batteries used in EVs and battery energy storage. They found that reusing and recycling the batteries could create U.S. market opportunities, stabilize the supply chain, reduce environmental impacts, and ease resource constraints.

And they found that a circular economy would derive more value from battery energy storage systems. Materials would be reused, recycled, or refurbished for multiple lifetimes rather than one-and-done, which uses up finite resources and creates waste.

Lithium-Ion Battery Recycling Finally Takes Off in North America and Europe


Later this year, 
the Canadian firm Li-Cyclewill begin constructing a US $175 million plant in Rochester, N.Y., on the grounds of what used to be the  Eastman Kodak complex. When completed, it will be the largest lithium-ion battery-recycling plant in North America.

The plant will have an eventual capacity of 25 metric kilotons of input material, recovering 95 percent or more of the cobalt, nickel, lithium, and other valuable elements through the company’s zero-wastewater, zero-emissions process. “We’ll be one of the largest domestic sources of nickel and lithium, as well as the only source of cobalt in the United States,” says Ajay Kochhar, Li-Cycle’s cofounder and CEO.

Founded in late 2016, the company is part of a booming industry focused on preventing tens of thousands of tons of lithium-ion batteries from entering landfills. Of the 180,000 metric tons of Li-ion batteries available for recycling worldwide in 2019, just a little over half were recycled. As lithium-ion battery production soars, so does interest in recycling.

But some observers aren’t convinced that QuantumScape’s lithium-metal batteries will power cars and trucks on the road as soon as the company claims.

Scientists have long seen lithium-metal batteries as an ideal technology for energy storage, leveraging the lightest metal on the periodic table to deliver cells jam-packed with energy.

But researchers and companies have tried and failed for decades to produce affordable, rechargeable versions that didn’t have a nasty habit of catching on fire.

Then earlier this year Jagdeep Singh, the chief executive of QuantumScape, claimed in an interview with The Mobilist that the heavily funded, stealth Silicon Valley company had cracked the key technical challenges. He added that VW expects to have the batteries in its cars and trucks by 2025, promising to slash the cost and boost the range of its electric vehicles.
