Solvay Ventures, the venture capital fund of Solvay, invested in Sepion, a California-based start-up that specializes in developing batteries with Li-metal anodes and liquid electrolytes. The $16 million round was led by Fine Structure Ventures, and also includes other climate tech investors. The company raised funds to accelerate commercialization of lithium metal batteries for long-range and low-cost electric vehicles.
Li-metal batteries enable high energy density and are strongly sought-after solutions for the electric vehicles market. However, the growth of dendrites can cause the batteries to fail and prevents them from having long life cycles. Sepion’s technology, which is based on an innovative polymeric membrane, prevents the growth of dendrites.
In addition to being a groundbreaking solution, Sepion’s technology can be readily adopted as it leverages the current Li-ion manufacturing infrastructure and liquid electrolytes. As a leader in Li-ion electrolyte additives, Solvay provides a complementary expertise to Sepion’s core technology.
