ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, AND MANUFACTURING METHOD OF ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

This electrode for a non-aqueous electrolyte secondary battery is provided with a current collector metal foil (110) having multiple projections (111) on at least one surface, and with an active material layer (120) which is formed on the surface of the current collector metal foil so as to embed the current collector metal foil, wherein openings (112) are formed in the tips of the projections, and grooves (121) around the projections are formed in the active substance layer.
