Abstract
The present disclosure relates to a current separation method and the like of a nonaqueous lithium power storage element. In the current separation method, the nonaqueous lithium power storage element includes a cell including: a positive electrode precursor that includes a positive electrode active material layer containing lithium carbonate and activated carbon; a negative electrode that includes a negative electrode active material layer containing a negative electrode active material capable of occluding and releasing lithium; a separator arranged between the positive electrode precursor and the negative electrode; and an electrolyte solution. The current separation method includes the step of calculating a capacitor current Iand an electrode reaction current Iof the cell based on voltage and current of the cell that are measured during doping of the cell.
