PURPOSE:To improve applicative ratio of active material in such a way that the intensity of an electrode is strengthened by adding electroconductive fiber into active material agent in particle. CONSTITUTION:A positive electrode agent 5 is housed into a positive electrode canister 4 made of stainless steel, etc. whereupon is laded a separator 6 impregnated electrolyte, and a negative electrode active material, such as lithium housed in a negative electrode canister 1 made of stainless steel is provided. A button-shaped battery is formed by hermetically enclosing with interposition of a resin enclosing packing 3 between the both canisters 1, 4. With the positive electrode agent 5 of this battery, as a positive electrode active material for example with use of manganess dioxide, whereto are added carbon particle and bonding agent of fluororesin, it is formulated by adding electroconductive fiber thereupon. As the electroconductive fiber, for example, carbon fiber, nickel fiber or the like is used. |
