More Information
Summary:Provided is a method for producing a lithium secondary cell with which the concentrated precipitation of metal impurities at the negative electrode is inhibited and short circuiting is unlikely to occur. The production method includes, assembling together the positive electrode, the separator, and the negative electrode, and then impregnating the assembly with the nonaqueous electrolyte; charging the assembly within 1 min so that a maximum achieved potential of the positive electrode becomes 3.2 V or more with respect to the redox potential of lithium; allowing the assembly to stand for 10 min or less after the charging has ended; and discharging the assembly within 1 min after the standing step.
