Document Type and Number:
WIPO Patent Application WO/2019/146413
Kind Code:
A1
Abstract:
A positive electrode according to one embodiment of the present invention is provided with: a positive electrode collector; a positive electrode mixture layer which is formed on at least one surface of the positive electrode collector; and an intermediate layer which is interposed between the positive electrode collector and the positive electrode mixture layer. The intermediate layer is configured from: insulating inorganic particles that have a thermal conductivity of less than 50 W/mK; highly heat conductive particles that have a thermal conductivity of 50 W/mK or more; a thermoplastic resin; and a polyvinylidene fluoride. The content of the inorganic particles is 50% by mass or more relative to the mass of the intermediate layer.
