| This paper summarizes the influencing factors and research status of aluminum-plastic film forming performance, and provides references for the research and technical personnel in the field of aluminum-plastic laminated film of soft encapsulated lithium-ion battery to conduct in-depth research and improve product performance. Firstly, the structure and function of the aluminum-plastic laminated film multi-layer composite material and the function of each layer is introduced. Then the influence of stamping die, stamping process and the selection of the base material on the forming performance of the aluminum-plastic laminated film is discussed. The effects of the alloy composition, microstructure and grain size of the aluminum foil base layer on the performance of the aluminum foil are reviewed in detail. To sum up, in order to accelerate the localization process of aluminum-plastic laminated film for lithium-ion battery, it is necessary to strengthen the durability of aluminum-plastic laminated film to electrolyte in the future. At the same time, further improve the forming performance of aluminum foil, strengthen the research on the influence mechanism of aluminum foil interface property on aluminum-plastic composite performance and aluminum plastic laminated film durability, provide theoretical support to enhance the downstream users' confidence in domestic aluminum-plastic laminated film. |
