SK On teams up with Factorial to start push for mass production of 1,200-km solid-state batteries

Battery maker SK On is partnering with U.S. battery startup Factorial Energy to assess whether solid-state batteries can be mass-produced using SK On’s existing lithium-ion production lines. Under an MOU, the companies will review how SK On plants and equipment can support Factorial’s FEST solid-state technology. Factorial is conducting vehicle validation in North America with Stellantis, which has disclosed performance data for a 77Ah FEST cell. Factorial also works with other automakers and has signed similar non-binding agreements with materials companies.

China develops high-performance electrolyte for all-solid-state batteries, maintaining 84 percent capacity after 350 cycles

Chinese researchers have developed a new electrolyte system for all-solid-state batteries that maintained 84.15 percent of its initial capacity after 350 charge-discharge cycles. The team at the Chinese Academy of Sciences\' Dalian Institute of Chemical Physics applied a PVDF-based gel composite electrolyte and focused on reactions between lithium oxychloride and PVDF to improve bonding and ion conduction. The study did not provide figures for energy density, driving range or charging speed.

Stellantis, Factorial begin first solid-state battery road test in North America

Stellantis and solid-state battery developer Factorial Energy have begun the first on-road test of a solid-state electric vehicle battery in North America. The companies are using a Dodge Charger Daytona development vehicle equipped with Factorial\'s FEST cells. They said the test is the first to integrate a solid-state battery into a North American EV platform for validation in real road conditions. Factorial recently listed on Nasdaq under the symbol FAC.
