Title:
CURRENT SEPARATION METHOD FOR NON-AQUEOUS LITHIUM POWER STORAGE ELEMENT, DOPING METHOD, AND DOPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/105818
Kind Code:
A1
Abstract:
One purpose of the present disclosure is to provide a doping method with which it is possible to estimate the progress of a principal reaction in a lithium carbonate decomposition doping step in a non-aqueous lithium power storage element. A current separation method, doping method, and doping device according to the present disclosure involve calculating a capacitor current density iC and an electrode reaction current density iR on the basis of a voltage and a current in a cell measured cell during doping of the cell.
