SOLID CELL AND ITS MANUFACTURE

摘要

PURPOSE:To obtain a simple and economical solid secondary cell by using a high molecular film electrolyzed and oxidized with a high molecular monomer film in a solid phase as a positive electrode active material. CONSTITUTION:A high molecular film obtained by electrolyzing and oxidizing a high molecular monomer film in a solid phase is used as a positive electrode active material. The high molecular film with oxidation-reduction property is obtained by polymerizing the monomer film with little projections and recesses as it is, the monomer is suppressed from being eluted into a solution or a solid electrolyte during the electrolyzation reaction, and the quantity of a negative electrode active material and the film thickness or the like can be set in advance. A solid secondary cell with no dispersion in quality and performance is thereby obtained, and a delicate film with little projections and recesses is electrolyzed and oxidized for use in a solid phase, thus the solid cell with large charging and discharging capacities and the high voltage is obtained.
