MANUFACTURE OF NONAQUEOUS SOLVENT BATTERY

摘要

PURPOSE:To obtain a battery whose voltage drop in an initial stage of high rate discharge is small and recovery time of voltage is short by performing a specified capacity of discharge as post-treatment after assembly of a nonaqueous solvent battery. CONSTITUTION:A negative electrode 2 such as lithium and a positive electrode 3 are accommodated into a can 1 with separators 41 and 42 interposed between them, then electrolyte 13 which also serves as positive active material mainly comprising sulfur oxyhalide is put therein to fabricate a nonaqueous solvent battery. After the battery was assembled, preferably within 10 days, the battery is discharged by 0.5-10% of the total discharge capacity by constant current discharge procedure. By this post-treatment, a battery having good discharge performance whose voltage or current is steady is obtained.
