CTO at Sepion Technologies, a battery materials company focused on development of innovative polymer and electrolyte technologies to enable lithium batteries - both Li-ion and Li-metal! Sepion's patented polymer technology has interesting properties that permits free travel of lithium ions, but blocks nearly everything else. The polymer also has very consistent pore structure that we believe helps homogenize lithium concentration gradients during charge and discharge. The polymer layer is coated onto conventional base-layer separators, and intended to be cost-parity with a ceramic-coated separator. For Li-ion, Sepion's material blocks transition metals (making thermal events rarer), promotes electrolyte wetting, and reduces H2O content compared to ceramic-coated separators. For Li-metal, the material also facilitates safe use of liquid electrolyte, and brings Li-metal anodes to a world in which fast charge performance is paramount.Interested? Feel free to contact me!
