  • Process for producing a positive electrode for a non-aqueous electrolytic cell
    Patent number: 4297231
    Abstract: Disclosed is a process for producing a positive electrode for a non-aqueous electrolytic cell. Manganese dioxide is heat-treated at a temperature between 250.degree. and 400.degree. C. The heat-treated manganese dioxide is next mixed with a conducting agent and binder. The binder is suspended in water by means of non-ionic surface active agent, and the mixture is heat-treated at a temperature between 180.degree. and 350.degree. C. and then pressured molded into a positive electrode. This production process allows the provision of a positive electrode for a non-aqueous electrolytic cell of excellent discharge characteristics.
