NOVELTY - Coating lithium battery pole piece involves synchronously coating the conductive carbon layer slurry, lithium battery slurry and polyvinylidene fluoride glue slurry on the surface of the foil from the inside to the outside through the multi-layer slope coating process. USE - Method for coating lithium battery pole piece. ADVANTAGE - The method optimizes the pore distribution of the coating layer of the prepared positive/negative pole piece, and ensures good wettability and rate charge and discharge performance of the lithium battery cell.
