PURPOSE:To provide a lithium secondary battery-positive electrode by which a thin type battery having a large area can be realized and which has an excellent capacity and cycle stability. CONSTITUTION:Vanadium pentoxide is used as a positive electrode active material, and acetylene black is used as an electric conductive agent, and polyvinyl butyral is used as a binder. These materials are dispersed by using alcoholic solution of the vanadium pentoxide so as to be formed in slurry, and after its slurry is casted on a SUS foil in a sheet shape by means of a doctor blade method, it is dried up, and is made into a porous body, so that a positive electrode having thickness of 100-200mum can be obtained. |
