Abstract
A positive electrode is composed of a film-shaped active material, which is composed of a conducting polymer serving as a first active material, and an electrochemical active material serving as a second active material which is uniformly dispersed in the shape of particles in the conducting polymer, with the parts-by-weight ratio of the second active material to the first active material being 3 to 9 parts of the second active material to 7 to 1 part of the first active material, when the total of the first active material and the second active material is 10 parts. A secondary battery is fabricated using the above positive electrode.
