Solid electrolyte cell

Abstract

Abstract PURPOSE:To obtain the captioned cell having a small thickness and maintaining a stable open-circuit voltage for a long time at a low cost by allowing the specified amount of lithium-ion-conductive electrolyte to be contained in a thin film made of a variety of high polymeric resin, in a lithium solid electrolyte cell. CONSTITUTION:A negative electrode layer is made of metal lithium, and a solid electrolyte layer consists of the thin film made of high polymeric resin such as polyvinylidene fluoride etc. which contains the electrolyte such as lithium perchlorate in the amount of 1-50mol% for the molar amount of the high polymeric resin, and a positive elecrode contains the compounds such as titanium disulfide etc. as activating substance. The solid electrolyte layer consists of the solid thin film which is formed through the processes in which the viscous solution is obtained by dissolving high polymeric resin powder into an organic solvent such as dimethyl formaide etc., and the electrolyte powder is added and dissolved into said viscous solution, and the obtained solution is casted onto the smooth plate made of PTFE and dried, and a part of the organic solvent is dispersed.
