PURPOSE:To prevent gas generation and performance deterioration during preservation even if no preliminary discharge is performed, and simplify a production line by allowing metal hydrogen complex compound to react with positive electrode active material before electrolyte is poured on the positive electrode active material. CONSTITUTION:Positive electrode active material 2, formed into a flat disc shape, is pressure connected onto the inside bottom face of a positive can 1 via a metal net collector. The active material 2, produced by mixing manganese dioxide of 9, graphite of 1, and Teflon of 0.2, is formed into a disc shape. After dry processing, 100 microliter of lithium aluminum hydride 3 is poured against per 1 gram of the active material 2 in the can 1. A separator 4 is set on the active material 2 and electrolyte 5 is poured. Lithium perchlorate is dissolved in mixture liquid of the same amount of propylene carbonate and dimethoxyethane so as to form the electrolyte 5. Thereafter, a negative electrode terminal plate 7, to which negative electrode active material 6, made of metal lithium, is pressure connected, and a sealing gasket 8 are combined with the positive electrode can 1 so that a battery is assembled. |
