ELECTRODE PLATE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

WIPO Patent Application WO/2010/134258

A1

Disclosed is an electrode plate for a nonaqueous electrolyte secondary battery, which is capable of preventing a short-circuit when the nonaqueous electrolyte secondary battery is broken by the application of pressure. Specifically disclosed is an electrode plate for a nonaqueous electrolyte secondary battery, which comprises a collector (10) that is formed of a strip-shaped metal foil, mixture layers (9) that contain an active material and are respectively formed on the both surfaces of the collector, and a lead-out line (11) that is connected to the collector (10). The collector (10) has an exposed portion (13) on both surfaces of which a mixture layer (9) is not present, and the exposed portion (13) extends perpendicular to the longitudinal direction of the collector (10). The lead-out line (11) is connected to one surface of the exposed portion (13), and the width of the surface where the mixture layer (9) is not present is larger than the width of the other surface where the mixture layer (9) is not present.
