Conformal Graphene Encapsulation for Next Gen Li-ion Cathode Materials

Volexion is commercializing a drop-in pristine graphene encapsulation solution, stabilizing and enhancing Li-ion materials, specifically cathodes. By controlling the material/electrolyte interface thanks to a pinhole free conformal graphene composite, Volexion's end-to-end solution drives a multi-functional performance improvement in cycle life, gassing reduction & safety, rate capability, voltage range extension, reduction of inactive materials, and wide temperature range operability. Beyond improving current materials, Volexion is an enabling technology for next generation materials such as high-voltage spinel and Lithium and Manganese-rich chemistries. Developed jointly at Argonne National Laboratory and Northwestern University, Volexion's drop-in technology is immediately usable in existing manufacturing lines and is scaling-up its production capacity to serve industrial partners.
