PURPOSE:To obtain a battery having small size and good charge discharge performance by using a composite oxide crystal having a composition formula of LiVO3 as a positive active material, lithium or lithium alloy as a negative active material, and a substance movable for electrochemical reaction as an electrolyte. CONSTITUTION:A positive mix pellet 6 is formed by pressing a mixture of LiVO3 powder and a binder such as polytetrafluoroethylene powder against a positive case 3 made of stainless steel. A metallic lithium negative electrode 4 pressed against a stainless steel sealing plate 1, then a gasket 2 is fitted. An electrolyte prepared by dissolving 1N LiClO4 in an equal volume mixture of propylene carbonate and 2-dimethoxyethane is impregnated in a propylene microporous separator 5. A positive case 3 is fitted to the sealing plate 1 through the gasket 2 and crimped to form a battery. A coin type battery having large capacity and good charge-discharge cycle performance is manufactured. |
