Solvay Ventures, the funding asset of Solvay, put resources into Sepion, a California-based beginning up that has some expertise in cutting edge layers for batteries with Li-metal anodes and fluid electrolytes. The $16-million financing round was driven by Fine Structure Ventures, and furthermore incorporates other environment tech financial backers.
Sepion raised assets to speed up commercialization of lithium metal batteries for long-reach and minimal expense electric vehicles.
Li-metal batteries empower high energy thickness and are unequivocally pursued answers for the electric vehicles market. Nonetheless, the development of dendrites can make the batteries fall flat and keeps them from having long life cycles. Sepion’s innovation, which depends on an imaginative polymeric film, forestalls the development of dendrites.
Sepion’s innovation can be promptly taken on as it use the current Li-particle fabricating framework and fluid electrolytes. As a forerunner in Li-particle electrolyte added substances, Solvay gives a reciprocal ability to Sepion’s center innovation.
This is exactly the mission of our battery platform and by investing in Sepion’s technology, we are progressing in our journey to enable safer, more performing and more sustainable batteries.

With the help of the ARPA-E IONICS (prior post) and CalSEED programs, Sepion has fostered a nano-permeable polymer film that works on the exhibition of lithium metal anodes, promising a 40% expansion in EV range, a 20% decrease in cost, and further developed security.
Sepion’s present item, a lithium-cathode sub-get together (LESA) comprising of the layer and lithium metal anode, is intended to coordinate with existing lithium-particle producing framework bringing the boundary down to advertise reception.
This coordination is refined with a crossover lithium metal cell plan in which a strong lithium metal anode, ensured by Sepion’s film, is combined with a customary metal oxide cathode and fluid electrolyte. This would empower a current Gigafactory to turn into a 1.4-overlap Gigafactory essentially by changing to Sepion’s LESA part and cell plan.
In March, the California Energy Commission granted Sepion a $1.4-million award to propel the improvement of its protected sans anode crossover lithium-metal cells from a lab-scale approval to a pre-model. This undertaking, which goes through March 2024, will upgrade two key parts—the electrolyte and current gatherer, that intensely impact the security, cycle life, quick charge abilities, and cost of completed lithium-metal batteries.
Cooperative energies between Sepion’s film and the upgraded electrolyte will additionally separate cross breed lithium-metal cells emerging from this program and hoist the full cell plan from innovation availability level (TRL) 4 to TRL 6.
Sepion will create and approve model lithium-metal cells with driving car producers.
