| titleOfInvention | A cell fabrication process based on dry film formation |
| abstract | The invention provides a battery cell preparation process based on dry film formation. The process firstly combines the self-supporting positive and negative electrode dry film obtained by the dry process preparation process with positive and negative electrode current collectors to obtain positive and negative electrode sheets; Then part of the dry film is scraped off to leave a blank area; finally, the positive and negative electrode sheets are combined with the separator and then Z-folded as a whole to obtain a finished battery cell. At the same time, the present invention also discloses a battery including the above-mentioned battery cell. Based on the battery cell preparation process provided by the invention, which is different from the traditional winding type battery core and laminated type battery core, the generation of burrs and kink portion stress on the die-cut edge during production can be effectively avoided, and the production of the battery core can be improved. Efficiency and safety performance, simple process leads to reduction of equipment structure and cost. The battery cell prepared based on the invention can be used in a battery to increase the electrochemical stability and safety of the cycle process. |
