Composite of polypyrrole and crystalline V 2 O 5 powder was prepared by chemical oxidation of pyrrole with use of V 2 O 5 powder itself as an oxidizing agent. The V 2 O 5 content was changed from 0 to 94 wt% by changing the amount of V 2 O 5 dispersed in the preparation bath. The pellet electrodes could be prepared by pressing the composite powder alone even if amount of polypyrrole in the composite was only 6 wt%. The resulting pellet electrode exhibited good charge‐discharge performance as a positive electrode of Li rechargeable battery in an electrolyte solution as well as in a quasi‐solid cell fabricated by using a gel electrolyte sheet of poly(methyl methacrylate).
