Abrégé
(EN)
The invention provides a novel lithium pre-embedding method of a lithium ion capacitor. The method comprises the following steps that (1) a battery cell is assembled, and is soaked into an organic solution containing lithium salts; (2) a positive electrode and a negative electrode are respectively connected with a charging and discharging test instrument, and once discharging after once charging is used as a cycle, 1 to 1000 times of cycles are totally carried out, and the lithium pre-embedding on the negative electrode is completed; (3) the battery cell after the lithium pre-embedding completion is taken out and is put into a packaging case, the packaging case is filled with electrolyte and is assembled into a lithium ion capacitor single body. When the method is adopted, the problem of too high cost due to lithium metal, porous current collectors and the like can be effectively solved, the safety can be improved, the technical flow process can be simplified, and the method is applicable to industrial production.
