MANUFACTURE OF NONAQUEOUS SECONDARY BATTERY

摘要

PURPOSE:To stabilize discharge voltage and to suppress a rise of battery internal resistance at storage time by proposing a condition of chemical conversion treatment suited for a nonaqueous secondary battery providing a positive pole with rechargeable manganese oxide serving as the active material and a negative pole consisting of lithium-aluminum. CONSTITUTION:Preliminary discharge is performed of 10 to 30% positive pole capacity and 2 to 12% negative pole capacity of a nonaqueous secondary battery to set this current density to 5 to 20mA/cm<2>.
