Title:
CURRENT SEPARATION METHOD FOR NONAQUEOUS LITHIUM POWER STORAGE ELEMENT, PREDICTION METHOD, SYSTEM AND LIKE
Document Type and Number:
WIPO Patent Application WO/2023/105817
Kind Code:
A1
Abstract:
The present disclosure relates to a current separation method for a nonaqueous lithium power storage element, and the like. With respect to a current separation method according to the present disclosure, the nonaqueous lithium power storage element contains a cell which comprises a positive electrode precursor having a positive electrode active material layer that contains lithium carbonate and activated carbon, a negative electrode having a negative electrode active material layer that contains a negative electrode active material that is capable of absorbing and desorbing lithium, a separator that is arranged between the positive electrode precursor and the negative electrode, and an electrolyte solution. The current separation method comprises a step for calculating the capacitor current IC and the electrode reaction current Id of the cell on the basis of the voltage and the current of the cell measured during doping of the cell.
