Process for preventing lithium ion battery pole piece from powder shedding during processing

The invention discloses a process for preventing a lithium ion battery pole piece from powder shedding during processing. The process is characterized in that a layer of glue or ceramic coating is applied on a surface of the lithium ion battery pole piece, the glue layer or the ceramic coating completely covers a coating area of the lithium ion battery pole piece, wherein the glue layer is formedby dissolving CMC in the deionized water or dissolving PVDF in NMP to prepare glue solution coated on the coating of the lithium ion battery pole piece and drying the coated lithium ion battery pole piece, and the ceramic coating is prepared by mixing and stirring the ceramic powder and the PVDF glue solution, coating the mixture on the coating of the lithium ion battery pole piece and drying thecoated lithium ion battery pole piece. The process is advantaged in that the powder material can be prevented from shedding from the pole piece, adhesion between the pole piece and a diaphragm is improved, hot pressing and sha
