US-based Sepion Technologies, which develops nanoengineered separator coatings and liquid electrolytes for EV batteries, has received UN/DOT 38.3 safety certification for its lithium-metal pouch cells.

UN/DOT 38.3 is an essential certification required for manufacturers and suppliers involved in transporting and distributing lithium batteries by air, sea and land to ensure the safety of passengers, crew and cargo. Having received the certification, Sepion can commence shipping lithium-metal cell samples to its customers worldwide.

Sepion has demonstrated compliance with environmental, mechanical and electrical requirements, including altitude simulation, thermal cycling under extreme temperatures, vibration tests and shock resistance assessments, external short circuit simulations, impact simulations and forced discharge evaluations.

Sepion’s lithium-battery technology comprises nanoporous separator coatings and non-flammable liquid electrolytes designed to address the safety challenges posed by traditional lithium-ion batteries while offering enhanced energy density and faster charging at a competitive cost, according to the company.

“We aim to unlock greater design optionality for EV manufacturers to deliver safe and sustainable vehicles that meet the diverse needs of the next wave of EV customers. We do this by providing separators and electrolytes for commercial and next-gen active materials at a competitive cost,” said Peter Frischmann, Sepion’s CEO.
