PROBLEM TO BE SOLVED: To provide a lithium battery manufacturing method capable of improving safety and productivity while achieving good long-term storage performance.SOLUTION: The method includes: a step of housing a negative electrode material 4 made of lithium and a lithium alloy, a positive electrode material 3, and an organic electrolyte in a battery can 2 on which one of positive and negative electrode terminal parts 11 is formed, and assembling a lithium battery 1 by sealing an opening 13 of the battery can by a sealing body 9 also serving as the other electrode terminal part 7; and a preliminary discharging step s12 of discharging a predetermined ratio of electric capacitance relative to a theoretical capacity to the assembled lithium battery. In the preliminary discharging step, a load of 20 &OHgr; or more and 50 &OHgr; or less is connected and discharged between one electrode terminal part and the other electrode terminal part. |
