MANUFACTURING METHOD FOR NON-AQUEOUS ELECTROLYTE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for realizing high discharging voltages or large discharging capacities matching the excellent characteristics of a non-aqueous electrolyte battery such as a lithium ion secondary battery. SOLUTION: A composition which is expected to vaporize when dripping and impregnating the composition into an electrode laminated body 7 in a reduced pressure or a vacuum is beforehand included in a non-aqueous electrolyte (not shown in Fig.) in a larger mix ratio with the volume expected to vaporize increased. By dripping the non-aqueous electrolyte into the electrode laminated body 7 for a predetermined period of time, the predetermined composition is impregnated into the electrode laminated body 7 in a prescribed mix ratio.
