TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Compounds: The inorganic compound is barium titanate (BaTiO3) and/or titania (TiO2), and exhibits ferroelectricity and paraelectricity. The non-aqueous electrolyte and gelated electrolyte (as electrolytic salt) contain LiPF6, LiBF4, LiN(C2F5SO2)2, LiN(CF3SO2)2 and LiCF3SO3.The cathode contains a substance capable of doping and undoping lithium, as active material and the anode contains lithium oxide compound as active material.    TECHNOLOGY FOCUS - POLYMERS - Preferred Materials: The separator is formed of high molecular materials containing olefin and/or vinylidene fluoride, as repetitive unit. EXAMPLE - 90 weight parts (wt.pts) of pulverized graphite powder and 10 wt.pts of polyvinylidene fluoride (binder), were mixed to form a cathode mixture which was dispersed in N-methyl pyrrolidone to form a slurry. The slurry was then coated uniformly on a strip-shaped copper foil, dried and compression-molded in a roll press to form a layer of cathode active material.    Lithium carbonate and cobalt carbonate were mixed at a molar ratio of 0.5-1.0, and sintered in air at 900degreesC for 5 hours to form LiCoO2. 91 wt.pts of the LiCoO2, 6 wt.pts of graphite, and 3 wt.pts of polyvinylidene fluoride, were mixed to form an anode mixture which was dispersed in N-methyl pyrrolidone to form a slurry. The slurry was coated uniformly on a strip-shaped aluminum foil, dried and compression-molded in a roll press to form a layer of anode active material.    A gelated electrolyte was prepared, by mixing 12 wt.pts of ethylene carbonate (EC), 6 wt.pts of propylene carbonate (PC) and 6 wt.pts of LiPF6 (electrolytic salt), to form a plasticizer. To this plasticizer 10 wt.pts of block copolymer (vinylidene fluoride-co-hexafluoropropylene) having a molecular weight of 600000, 60 wt.pts of diethyl carbonate, were mixed and dissolved. The resulting solution was uniformly coated on one surface of each of the layers of the anode and cathode active materials for impregnation. The resulting product was allowed to stand at room temperature for 8 hours to vaporize diethyl carbonate off to form a gelated electrolyte. Finally, the layers of the anode and cathode active materials, coated with the gelated electrolyte was press-fitted to each other, with the surfaces carrying the gelated electrolyte facing each other, to fabricate a non-aqueous electrolyte cell 2.5 cm x 4.0 cm x 0.3 mm in size. The cell was found to have cyclic characteristics of 89%, load characteristics of 82% and low temperature characteristics of 83%.
