RECHARGEABLE NONAQUEOUS ELECTROLYTIC BATTERY

摘要

A rechargeable nonaqueous electrolytic battery comprises a positive plate containing a compound oxide of lithium and manganese, a negative plate capable of occluding and releasing lithium, and a nonaqueous electrolytic solution. The negative plate contains at least any of sodium (Na), potassium (K), calcium (Ca) and strontium (Sr), which decreases the deterioration of the negative plate and maintains battery performances if the battery is stored at high temperature and if it charges and discharges at high temperature.
