Sakuu develops the first battery in its new solid-state product line
Additive manufacturing specialist Sakuu has developed a lithium metal battery that achieved an energy density of 800 Wh/l in recent testing. The company says its battery achieves an energy density of 500-700 Wh/l, or greater. It demonstrates an energy retention rate of 97% after 200 cycles, and Sakuu expects it to reach an 80% retention… Read more »
Mercedes-Benz teams up with ProLogium on solid-state batteries
Mercedes-Benz and battery firm ProLogium are teaming up to develop solid-state batteries. The automaker will make an unspecified investment in ProLogium, and will take a seat on the company’s board of directors. The first test vehicles using the new batteries are not expected to appear for several years. “We believe that range and efficiency are… Read more »
Factorial Energy raises $200 million for solid-state battery tech
Massachusetts-based solid-state battery developer Factorial Energy raised $200 million in a Series D funding round from Mercedes-Benz and Stellantis. It will use the funding for research and development, commercial production and the deployment of batteries with its Factorial Electrolyte System Technology (FEST) electrolyte. While Stellantis announced 2026 as its goal for introducing the first competitive… Read more »
Factorial Energy and Hyundai partner to test solid-state battery technology
Factorial Energy and Hyundai are partnering to test Factorial’s solid-state battery technology and its implementation in Hyundai EVs. The companies will integrate Factorial’s technology at the cell, module and system levels, perform vehicle-level integration, and co-develop specifications for manufacturing Factorial’s batteries. Factorial’s FEST (Factorial Electrolyte System Technology) platform leverages a proprietary solid electrolyte material that… Read more »
Stellantis and Factorial Energy team up to develop solid-state batteries
Stellantis and Massachusetts-based solid-state battery developer Factorial Energy have signed a joint development agreement to advance Factorial’s high-voltage solid-state battery technology. The agreement also includes a strategic investment from Stellantis. Factorial says its solid-state batteries offer 20 to 50 percent more range and increased safety, at the same cost as conventional lithium-ion batteries. The company’s… Read more »
Nissan announces $18 billion in new e-mobility investment, including solid-state batteries and 15 new EVs
Nissan, an early EV pioneer that later seemed to lose interest, has become the latest automaker to announce a new electrification plan. The company’s Nissan Ambition 2030 strategy calls for investments of 2 trillion yen (around $17.6 billion) over the next five years. “With Nissan Ambition 2030, we will drive the new age of electrification,… Read more »

Solid-state battery firm LiNa secures £3.5 million in seed funding
LiNa Energy has closed a £3.5-million ($4.78-million) late seed funding round. LiNa is commercializing a cobalt- and lithium-free solid-state sodium battery. The company claims its design has the potential to exceed the performance of both lithium-ion and sodium-ion technologies at a cost of less than $50/kWh. The funding, along with recently obtained grant money, enables… Read more »
Solid Power says safety tests show its solid-state battery tech is safer than current chemistries
Colorado-based Solid Power, a solid-state battery specialist that has backing from Ford and BMW, says recent third-party safety tests demonstrate that its battery cells, which use a sulfide-based solid electrolyte, are safer than current lithium-ion cells, which use a liquid or gel electrolyte. The tests aimed to simulate abuse and damage to Solid Power’s prototype… Read more »
