(Summary description)The production and manufacture of lithium-ion batteries are closely linked by each process step. Generally speaking, the production of lithium batteries consists of three parts: the fabrication of the electrode, the fabrication of the cell and the assembly of the battery. There are several key processes in these three processes, and the performance of batteries produced by different production processes is very different. The addition of plasma cleaning in the three processes can greatly improve the level of battery manufacturing. PLASMA cleaning is used before PLASMA coating: The anode and cathode pieces of lithium battery are made by coating the anode and cathode materials of lithium battery on the metal thin strip. When coating the electrode material, the metal thin strip needs to be cleaned. The metal thin strip is usually aluminum thin or copper thin. Plasma dry cleaning machine effectively solve the above problems. Plasma cleaning before battery welding: Plasma cleaning is a dry cleaning, mainly depends on the active ion in the plasma "activation" to remove the object surface stains. This method can effectively remove the dirt and dust on the end face of the battery pole column, and make preparation for the battery welding in advance, so as to reduce the defective products of welding. PLASMA cleaning during battery assembly: In order to prevent lithium battery from safety accidents, it is generally necessary to glue the lithium battery cell to play the role of insulation, prevent the occurrence of short circuit, protect the circuit and prevent scratch. Clean the insulation board and end board, clean the dirty surface of the cell, roughen the surface of the cell, and improve the adhesion of adhesive or glue coating. Depending on the "five actions" of the active particles in the plasma, the bonding, bonding, welding, coating, bonding and removing adhesive effects can be enhanced. The pollutants may be organic matter, epoxy resin, photoresist, oxide, particulate pollutants, etc. Different cleaning processes should be adopted for different pollutants, and different process gases should be selected.
