Abstract
A production method for a lithium-ion secondary battery includes configuring an electrode group provided with a positive electrode and a negative electrode, storing the electrode group, electrolytic solution, and a third electrode in a housing, charging the negative electrode by performing charging between the third electrode and the negative electrode inside the housing, and discharging the charged negative electrode by performing discharging between the third electrode and the negative electrode, thereby producing the lithium-ion secondary battery.
