TREATMENT FOR IMPROVED CONDUCTIVITY OF COLLECTOR-ELECTRODE INTERFACE IN LAMINATED LITHIUM-ION RECHARGEABLE BATTERIES

摘要

A coating of a vinylidene fluoride polymer on a metal foil is heated at about 350 DEG C to 450 DEG C in a non-oxidizing atmosphere of inert gas to provide a rechargeable battery current collector having an exceptional bonding surface which maintains a long-lasting and highly-conductive laminate interface with an associated polymeric battery electrode composition.
