Abstract

Systems and methods are provided for a reaction barrier between an electrode active material and a current collector. An electrode may comprise an active material, a metal foil, and a polymer. The polymer (such as polyamide-imide (PAI)) may be configured to provide a carbonized barrier between the active material and the metal foil after pyrolysis.
