Sepion Technologies, a US-based company specializing in nanoengineered separator coatings and liquid electrolytes for electric vehicle (EV) batteries, has recently obtained UN/DOT 38.3 safety certification for its lithium-metal pouch cells. This certification is crucial for manufacturers and suppliers involved in the transportation and distribution of lithium batteries by air, sea, and land to ensure the safety of passengers, crew, and cargo. With this certification in hand, Sepion is now able to ship lithium-metal cell samples to its customers globally.
In order to receive the UN/DOT 38.3 certification, Sepion had to demonstrate compliance with various environmental, mechanical, and electrical requirements. This included tests such as altitude simulation, thermal cycling under extreme temperatures, vibration tests, shock resistance assessments, external short circuit simulations, impact simulations, and forced discharge evaluations. Through these tests, Sepion showcased the safety and reliability of their lithium-battery technology, which comprises nanoporous separator coatings and non-flammable liquid electrolytes designed to address the safety challenges associated with traditional lithium-ion batteries while also offering enhanced energy density and faster charging capabilities at a competitive cost.
The company’s goal is to enable greater design flexibility for EV manufacturers by providing separators and electrolytes for commercial and next-gen active materials at a competitive cost. By offering a solution that prioritizes safety and sustainability, Sepion aims to help EV manufacturers deliver vehicles that meet the diverse needs of the growing market for electric vehicles. As Peter Frischmann, Sepion’s CEO, stated, “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.”
Sepion’s lithium-battery technology stands out for its innovative approach to addressing the safety concerns surrounding lithium batteries while also improving energy density and charging speeds. By developing nanoporous separator coatings and non-flammable liquid electrolytes, the company has created a solution that not only meets stringent safety requirements but also offers tangible benefits in terms of performance and cost-efficiency. With the UN/DOT 38.3 certification in hand, Sepion is well-positioned to expand its reach and provide its advanced battery technology to customers worldwide.
Overall, Sepion Technologies’ achievement of UN/DOT 38.3 safety certification for its lithium-metal pouch cells represents a significant milestone in the company’s mission to revolutionize battery technology for electric vehicles. By prioritizing safety, sustainability, and performance in their innovative solutions, Sepion is poised to make a lasting impact on the EV industry.
