Factorial Energy, a solid-state battery developer, has received the United Nations (UN) 38.3 safety certification for its large-format automotive solid-state batteries. This makes Factorial the first Li-metal solid-state battery maker to receive certification for 100+Amp-Hour (Ah) cells.

The UN 38.3 certification is a globally recognized safety requirement to transport lithium-ion and lithium-metal batteries by air, land, or sea. It is achieved through a series of tests, including crush, thermal, vibration, shock, external short circuit, altitude simulation, and forced discharge, to ensure that the batteries can withstand a range of conditions without hazardous risks. As such, the certification now enables Factorial to ship its 100+Ah cells globally to customers and partners.

Analyst QuickTake: This certification follows the company unveiling its first 100Ah battery cell at CES in January 2023 . The product was developed as part of the joint development agreement formed between Factorial and Stellantis in November 2021. Furthermore, in August 2022 , the company announced that it will be investing USD 45 million to establish a new advanced manufacturing facility in Boston, Massachusetts. This will house Factorial’s pilot production to manufacture automotive-sized solid-state batteries at pre-production speed and volume. Operations were expected to begin in early 2023.
