Sepion Technologies has received UN/DOT 38.3 safety certification for its next-generation lithium-metal pouch cells. The company is a developer of nanoengineered separator coatings and liquid electrolytes that enable the adoption of faster charging, lower-cost, and energy-dense lithium-ion and lithium-metal batteries for e-mobility applications.
UN/DOT 38.3 certification is required for transporting lithium batteries by air, sea, and land to ensure the safety of passengers, crew, and cargo. It’s an essential certification for manufacturers and suppliers involved in transporting and distributing lithium batteries.
This safety certification empowers Sepion to commence shipping lithium-metal cell samples to its customers worldwide, effectively addressing a substantial backlog of demand.
“Through rigorous internal and external testing, our patented lithium-metal technology has consistently proven exceptional abuse tolerance, increased energy density, and fast re-chargeability,” said Sepion’s CTO, Brian Sisk.
Sepion’s lithium-battery technology comprises of nanoporous separator coatings and non-flammable liquid electrolytes which not only address the safety challenges posed by traditional lithium-ion batteries, but also offer enhanced energy density and faster charging at a competitive cost.
“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,” said Peter Frischmann, CEO at Sepion. “We do this by providing separators and electrolytes that bring out the best in all commercial and next-gen active materials at a competitive cost.”
With extensive testing led by an independent battery evaluation and certification lab based in the United States, Sepion has demonstrated compliance with demanding environmental, mechanical, and electrical requirements, including:
- Altitude simulation
- Thermal cycling under extreme temperatures
- Vibration tests
- Shock resistance assessments
- External short circuit simulations
- Crush/impact simulations
- Forced discharge evaluations
Sepion is actively developing separator coatings and liquid electrolytes in conjunction with Fortune 100 automotive OEMs, major battery suppliers, and raw material providers. The company is targeting the commercial introduction of a suite of products for lithium-ion and lithium-metal technologies, ushering in the next generation of batteries delivering greater safety, longer range, and a faster charging experience at lower cost for EV manufacturers and consumers.
