Abstract
A positive electrode plate for a lithium ion secondary battery is made of aluminum and includes a positive current collecting foil made of aluminum, in which at least a main surface portion constituting a main surface is porous, a positive active material layer formed on the main surface portion of the positive current collecting foil, and a coating layer, having electrical conductivity and corrosion resistance, formed between the positive current collecting foil and the positive active material layer to directly coat the main surface of the positive current collecting foil.
