Abstract

Disclosed is a positive electrode for secondary batteries, which comprises a collector and an electrode layer containing an active material, a conductive agent and a binder. The collector has a surface roughness Rzjis of not more than 5 μm, and the peel strength between the electrode layer and the collector is not less than 0.1 N/mm. Also disclosed is a nonaqueous electrolyte secondary battery using such a positive electrode for secondary batteries.
