COLLECTOR FOR BIPOLAR LITHIUM ION SECONDARY BATTERIES

摘要

A collector (3) for bipolar lithium ion secondary batteries of the present invention comprises: a first conductive layer (3A) that is obtained by adding a conductive filler to a base that contains an imide group-containing resin; and a second conductive layer (3B) that has a function of blocking lithium ions. The second conductive layer (3B) comprises: a blocking resin layer (3a) that is obtained by adding a conductive filler to a base that contains a resin which contains no imide group; and a metal layer (3b). This collector (3) for bipolar lithium ion secondary batteries is used in such a manner that the first conductive layer (3A) is on the positive electrode active material layer side with respect to the second conductive layer (3B).
