Lithium-ion conductive separator

Lithium-ion conductive separator

Solid Master Separator – Lithium-ion conductive supplied by Solid Energies Inc (SEI)

SEI's Li-ion conductive separator is a drop-in replacement for conventional separators that eliminates liquid electrolyte from the separator layer. By transporting Li-ions through a solid-state electrolyte coating layer, it mitigates thermal runaway, reduces cell resistance, and prevents irreversible capacity loss—delivering superior energy output and enhanced safety. Its cost-competitive design lowers bill of materials while enabling next-generation Li-metal, Li-oxygen, and Li-sulfur chemistries with higher energy density.
