Abstract
The present application discloses a preparation method, apparatus, device and medium for a No. 5 lithium-ion battery. The method includes: preparing a battery cell; selecting a steel material and stamping it to obtain an upper steel shell of the battery; determining bending parameters of the spring sheet based on user requirements and attribute parameters of the spring sheet; assembling a PCB board and the upper steel shell based on the bending parameters, bending a negative spring sheet on a side of the PCB board downwards, and bending a positive spring sheet at a bottom of the PCB board downwards, thus obtaining a complete step-down charging terminal; fitting the complete step-down charging terminal onto the battery cell to obtain a semi-finished product; and fixing the semi-finished product by roller pressing, and covering an insulating film on an outside of the semi-finished product to obtain a finished product of the battery.
