ELECTRODE MATERIAL, ELECTRODE, SECONDARY CELL, AND METHOD FOR PRODUCING ELECTRODE MATERIAL

WIPO Patent Application WO/2013/061890

A1

Provided is an electrode material of excellent tab weldability, and capable of forming thin films of the electrode material, and with which low internal resistance of the cell may be achieved. The electrode material (1) is equipped with a base material (1a) including metal foil, and a conductive substance (1b). The surface of the base material (1a) is constituted by an exposed flat portion and a plurality of depressions (average depth: 0.3 µm-3.0 µm inclusive). The conductive substance (1b), which is disposed in the depressions, is disposed in a staggered pattern on the surface of the base material (1a), and the coverage of the base material (1a) surface by the conductive substance (1b) is 1-80%.
