PROBLEM TO BE SOLVED: To suppress rise in resistance to electric charge motion and a diffusion resistance of a coin type secondary battery in that a positive plate, a separator, and a negative plate are laminated and contained in the battery, and then to improve charge/discharge characteristic. SOLUTION: The coin type secondary battery is constituted so that a thickness of the positive pole plate is 0.1 to 1.2 mm and an electric conduction agent to a positive pole mix is 8.2 to 14.0 weight %. |
