Qp為止之電池。
A lithium ion secondary battery comprising a positive electrode, a negative electrode, a separator and a nonaqueous electrolyte is provided, wherein the separator consists essentially of a porous sheet. The positive electrode active material and the negative electrode active material can be reversibly doped and de-doped such that, when Qp (mAh) is an electric charge necessary for causing total lithium contained in the positive electrode to be de-doped and Qn (mAh) is an electric charge necessary for causing lithium to fully dope the negative electrode, Qp > Qn, and the battery is charged at a charging current Ic (mA) in a range of 0.2 Qn/h < Ic < 2 Qn/h for charging an electric charge Qc (mAh) in a range of 1 < Qc/Qn < Qp/Qn, the doping of the positive electrode by lithium is started through lithium particles produced on the negative electrode by charging the battery and is continued up to Qc > Qp.
