PACKAGING MATERIAL FOR ELECTROCHEMICAL CELL

摘要

Provided is a packaging material for an electrochemical cell which prevents the occurrence of short circuits. A packaging material for an electrochemical cell configured by laminating a base material layer including: at least a resin film; a heat-adhesive layer including a heat-adhesive resin, the heat-adhesive layer being disposed on the innermost layer; and a barrier layer including a metal foil, the barrier layer being disposed between the base material layer and the heat-adhesive layer, wherein a chemical-conversion-treated layer including alumina particles and modified epoxy resin is formed on the surface of at least the heat adhesive layer side of the barrier layer.
