Abstract

Abstract: The structure design of the NMP recovery system in the lithium battery pole piece coating process has many technology difficulties, including the vacuum and infrared radiation heating technology. For vacuum system, after the analysis of its impact on the coating process, and the drying needs of the NMP recovery system, through the analytic hierarchy process, the most suitable infrared radiation heater type can be determined. The process of recovering gaseous NMP is numerically simulated, and the simulation results of the system flow performance are obtained. The parameters of the drying time, arrangement mode and other parameters are determined by the multi group experiments of infrared radiation heater and the data chart. It has a great influence on the recovery of NMP solvent, stability and efficiency, drying effect and the conductive property of the pole piece.

Key words: Lithium battery pole piece, NMP recovery system, vacuum system, infrared radiation, analytic hierarchy process
