Battery

Abstract

Abstract PURPOSE:To make steady electrical contact possible for a long time by fixing a conductive organic polymer electrode to an outer can directly or through a current collector. CONSTITUTION:A coin type battery is formed in such a way that a positive electrode 3, a negative electrode 4, and a separator 5 impregnated with electrolyte containing dopant are accommodating in outer cans 1a, 1b, then cans 1a and 1b are sealed via a gasket 2. A current collector 6 uses stainless steel mesh as it is which was used as an electrode in electrolytical polymerization of the positive electrode (polyaniline) 3 to keep close contact with the positive electrode 3. The current collector 6 is fixed to the outer can 1a by spotwelding 7. A negative current collector 8 made of stainless steel mesh is fixed to a negative electrode (Al-Li alloy) 4 by spot-welding, then fixed to the outer can 1b by spot-welding 9. Thereby, a battery having steady electrical contact can be obtained.
