The stacking battery process refers to dividing the coated cathode and anode mixture layers into predetermined sizes. Subsequently, the cathode electrode mixture layer, separator, and anode mixture layer are laminated in sequence, and then multiple “sandwich” structure layers are laminated in parallel to form an electrode core that can be packaged.
In particular, the separation can be better designed based on the requirements of the stacking process. This makes possible to reduce tolerances and save costs. In addition, an increase in overall battery pack power density is possible as tolerances can be designed in a more targeted manner.
