The UN 38.3 standard is a globally recognized requirement for the safe transportation of lithium-ion and lithium-metal batteries. It involves a series of rigorous tests, which are performed by a third-party agency, including crush, thermal, vibration, shock, external short circuit, altitude simulation, and forced discharge. These tests ensure the batteries can withstand various conditions without any hazardous risks and are mandatory for batteries that are transported by air, sea, or land. and was performed by a third-party agency.

“Receiving the UN 38.3 safety certification shortly after our CES preview of 100+Ah cell, is a huge accomplishment and signals that we are on the right track to building safer high energy density batteries,” said Siyu Huang, CEO of Factorial Energy. “This certification further demonstrates our focus on not only performance, but safety. We look forward to delivering 100+Ah batteries to our partners with the safety certification accomplished.”

Factorial is revolutionizing the battery industry with its proprietary FEST® (Factorial Electrolyte System Technology) solid-state battery, providing safer and up to 50% higher energy density batteries compared to lithium-ion batteries. This UN 38.3 certification enables Factorial to ship its 100+Ah cells globally to customers and partners, bringing the product another step closer toward achieving automotive qualification.
