When it comes to EVs, the mainstream press displays a curious mix of skepticism and credulousness (disasters and miracles generate clicks, but slow, steady progress does not). A recent announcement from Toyota concerning solid-state batteries got the world’s media all excited about a big boost for battery-electric cars. (A search for “EV Holy Grail” will… Read more »

Researchers recommend isostatic pressing for solid-state battery manufacture
After months of encouraging test findings, Oak Ridge National Laboratory (ORNL) battery researchers are suggesting that the solid-state battery industry focuses on isostatic pressing to commercialize next-generation batteries. Isostatic pressing employs fluids and gasses like water, oil, or argon within a machine to exert consistent pressure throughout a battery component, generating a homogeneous material. This… Read more »
Factorial earns UN 38.3 certification to ship 100 Ah solid-state batteries
Factorial Energy, a Massachusetts solid-state battery developer, has received UN 38.3 safety certification for its 100+ Ah automotive solid-state batteries. The UN 38.3 standard governs the safe transport of lithium-ion and lithium-metal batteries. It includes crush, thermal, vibration, shock, external short circuit, altitude simulation and forced discharge tests that are conducted by a third party…. Read more »
Umicore invests in Blue Current to scale up solid-state battery tech development
Belgian circular materials technology company Umicore has purchased a minority stake in California-based solid-state battery manufacturer Blue Current. This investment complements the companies’ joint development agreement (JDA) to integrate Umicore’s battery materials into Blue Current’s solid-state battery technology. By providing capital—in addition to supplying battery materials under the JDA—Umicore intends to drive market adoption of… Read more »
Ilika leads £8.2-million collaboration with industry experts to develop automotive solid-state battery
British solid-state battery manufacturer Ilika Technologies is leading a 24-month, £8.2-million Faraday Battery Challenge collaboration project. Code-named HISTORY, the project’s focus is on integrating high-silicon-content electrodes into the company’s Goliath solid-state battery in order to enable automotive-level performance. Ilika will receive a grant of £2.8 million from the project and will partner with the manufacturer… Read more »
Engineers find a novel way to control dendrite propagation in solid-state batteries
Solid-state batteries are a major focus for battery researchers, as they could offer weight and size reductions, as well as greater safety, compared to current Li-ion designs. However, they have a major drawback: dendrites, root-like structures that build up on the lithium surface and penetrate the solid electrolyte, eventually crossing from one electrode to the… Read more »
New electrode material preserves its volume, solving a major limitation of solid-state batteries
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 »
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 »
