| titleOfInvention | A method of comparing and judging the adhesive force of negative electrode sheet of lithium ion battery |
| abstract | The invention discloses a method for comparing and judging the adhesive force of a negative electrode sheet of a lithium ion battery. In the second step, each aluminum-plastic film bag is put into a negative electrode piece respectively; in the third step, an electrolyte solution containing a trace amount of water is added to each aluminum-plastic film bag respectively, and the electrolyte solution is sealed and sealed after the negative electrode plate is not passed; In the fourth step, put all the aluminum-plastic film bags into the oven at the same time and stand for a preset period of time, and then take out the negative electrode pieces respectively; According to the size of the bulging and peeling area on the surface of the pole piece, the adhesive force of multiple negative electrode pieces is compared and judged. The invention can accurately and reliably test the magnitude relationship of the bonding force between the active material powders of a plurality of negative electrode sheets and the negative electrode sheet current collector (ie foil), and find the abnormality of the electrode bonding force. |
