摘要： PURPOSE:To realize electric charging and reduce self electric discharging by using sulfur or lithium sulfide as positive electrode substance, and using a lithium ion conductive solid electrolyte as an electrolytic layer. CONSTITUTION:A pot contains Li2S and SiS2 in a molar ratio of 3:2, which is molten and heated up to 950 deg.C in the algon atmosphere, followed by heating for two hours, to be rapidly cooled by liquefied nitrogen, thus obtaining a 0.6 Li2S-0.4 SiS2 lithium ion conductive amorphous solid electrolyte. A carbon material of a large surface area is soaked in a solution of sulfur solved in carbon disulfide, followed by filtration and drying under a reduced pressure at a room temperature, thus obtaining a conductive material. The conductive material and the electrolyte are mixed at a weight ratio of 1:1, thereby obtaining a positive electrode material 1. The material 1 and a metal lithium foil 2 serving as a negative electrode are pressure-molded into an integral column having a diameter of 10mm via an electrolytic layer 3. A positive electrode lead terminal 4 and a negative lead terminal 5 are bonded to each other via carbon pastes 6, 7, and the whole of a battery element is sealed with an epoxy resin layer. Consequently, self electric discharging is reduced and electric charging can be realized.

摘要： PURPOSE:To provide a high-reliability battery stable at a high temperature and high humidity by using a high-temperature hardening resin for the sealing material of the total solid lithium battery. CONSTITUTION:A lithium ion conducting glassy solid electrolyte 2 expressed by 0.5Li2S-0.5SiS2 is obtained. Titanium disulfide TiS2 and solid electrolyte powder are mixed, and the mixture is pressurized and molded to obtain a disk- like positive electrode 1. A disk-like lithium sheet is used for a negative electrode 3. For the electrolyte 2, solid electrolyte powder is pressurized and molded, it is clipped by the positive electrode 1 and the negative electrode 3, a carbon paste is stuck, and it is bonded to terminals of electrodes. This battery is sealed with a thermosetting epoxy resin, and the resin is hardened via a heat treatment to obtain a lithium battery.
