A method for preparing a positive electrode for a non-aqueous electrolyte cell comprises applying a positive electrode-active material, an electrically conductive agent, a dispersion of polytetrafluoroethylene and a mixture of polyacrylic acid and water on one side or both sides of a supporting material, and then drying the coated supporting material at about 250.degree. C. for 5 to 10 hours.

Method for preparing positive electrode for non-aqueous electrolyte cell

Disclosed is a flat cell comprising a positive electrode metal plate, a negative electrode metal plate confronted with said positive electrode metal plate, and an adhesive sealing member for sealing the peripheral edge portions of said metal plates, characterized in that said sealing member has a three-layer structure in which ionomer resin pieces are disposed on the opposite sides of a polyethylene piece or an ethylene copolymer piece.
