Resumen de: WO2026045548A1

The present invention relates to the technical field of lithium-ion batteries, in particular to a lithium-ion supercapacitor cell and a formation method therefor. The negative/positive ratio of a lithium-ion supercapacitor is (1.1-2.2):1. The calculation formula for the negative/positive ratio is (AC×Ad×AL)/(Cc×Cd×CL). In the present invention, by means of a stepped low-current formation charging process, a uniform and stable SEI film is formed on a surface of an amorphous carbon negative electrode, and by means of increasing a formation cut-off voltage, the minimal potential of an anode reaches approximately 0.06 V at the end of the initial charging of a battery, thereby consuming some of irreversible active sites. Furthermore, due to the over-capacity design of the anode, the phenomenon of lithium plating on a surface of the anode can also be prevented when a battery cell is at a high cut-off voltage, thereby greatly improving the safety performance of the battery. In addition, the over-capacity anode also ensures the cycle life of the lithium-ion supercapacitor under high-rate charging and discharging.
