Document Type and Number:
WIPO Patent Application WO/2023/007962
Kind Code:
A1
Abstract:
An electrode according to one embodiment of the present invention is provided with a conductive intermediate layer that is arranged between a core material and a mixture layer. The mixture layer contains an active material and a first binder; and the intermediate layer contains a conductive material and a second binder. The conductive material has a particle size distribution which has a first peak that is within the particle diameter range from 0.005 µm to 0.07 µm and a second peak that is within the particle diameter range from 0.5 µm to 10 µm. The content of the particles that constitute the first peak is 1% by mass to 40% by mass of the mass of the conductive material. The second binder is mainly composed of a thermoplastic resin that has a melting point of 100°C to 200°C, and has a composition that is different from the composition of the first binder.
