Solid-state batteries (SSBs) offer several potential advantages over current lithium-ion batteries, including improved safety and faster charging. However, SSBs suffer from a problem that limits their durability. When lithium ions are inserted into or extracted from the electrodes, the crystalline structure of the material changes, making the electrode expand or shrink. These repeated changes in… Read more »

Delta Electronics demonstrates 400 kW solid-state transformer-based EV charger
Delta Electronics (Americas) demonstrated a next-generation SiC MOSFET solid-state transformer-based 400 kW EV charger at a recent event attended by representatives of project partners GM, DTE Energy and NextEnergy. Delta’s “extreme fast” EV charger uses a three-phase 13.8 kV medium-voltage SiC MOSFET SST topology. It provides 500 A of charging current, and the company claims… Read more »
Factorial Energy to open solid-state EV cell development and production facility
Factorial Energy, a Massachusetts-based solid-state battery developer, is building a solid-state cell development and manufacturing facility in Methuen, Massachusetts. “The existing 67,000-square-foot building on the site will undergo extensive buildout to house Factorial’s pilot production facility, which will manufacture automotive-sized solid-state batteries at pre-production speed and volume,” says the company. Factorial plans to invest $45… Read more »
Adden Energy receives exclusive tech license and seed funding for solid-state battery scale-up
Solid-state EV battery startup Adden Energy has received an exclusive technology license from Harvard University’s Office of Technology Development, and $5.15 million in seed financing from Primavera Capital Group, Rhapsody Venture Partners and MassVentures. Adden Energy plans to use the funding to scale up a solid-state coin-cell prototype developed by researchers in Xin Li’s Harvard laboratory…. Read more »
Toyota is the global leader in solid-state battery patents
It’s common for companies to espouse green policies in public, while privately pursuing opposite goals—but Toyota turns this familiar equation on its head. Other automakers tout their enthusiasm for EVs to the media, while pushing gas-guzzling SUVs to their customers. Toyota’s leaders speak against EVs in public, and the company actively lobbies against government support… Read more »
Solid-state battery developer Sakuu opens battery printing and engineering facility in Silicon Valley
Sakuu, developer of a 3D-printed solid-state battery, has opened an engineering hub for its battery platform printing initiatives in Silicon Valley. The company concluded a $62-million funding round earlier this year, and recently opened a pilot production line, which is currently producing batteries for clients. Sakuu’s new 79,000-square-foot facility is expected to house 115 employees… Read more »
