Abstract

PURPOSE:To increase the energy density and obtain an excellent charge/ discharge cycle characteristic by using a vanadium composite oxide with which 5-10 mole% of an oxide of the group VIII of the periodic table is mixed as a positive electrode active material. CONSTITUTION:As a positive electrode active material, a composite oxide obtained by adding and mixing 5-10mum of an oxide of the group VIII of the periodic table, for example, any of iron sesquioxide, tricobalt tetraoxide, or nickel oxide, with vanadium pentaoxide followed by heat treatment is used. A negative electrode is lithium or lithium alloy, and an electrolyte is obtained by dissolving a lithium salt such as lithium perchlorate, arsenic lithium hexafluoride, lithium trifluoromethane sulfonate in an aprotic organic solvent such as ethylene carbonate, propylene carbonate, 1,2-dimethoxyethane, and 2-methyltetrahydrofuran. Hence, the crystal structure fracturing of vanadium pentaoxide resulting from the insertion or elimination of lithium ion into the vanadium pentaoxide crystal lattice in the charge/discharge cycle is relieved, and the charge/discharge cycle characteristic is improved.
