锂电池极片不平度研究与辊压机结构优化分析
Research on Unevenness of Lithium Battery Pole Piece and Analysis on Structural Optimization of Roller Press
摘要
Abstract
After measuring the thickness for normal pole piece of lithium battery after the process of rolling,the author has discovered that the thickness of pole piece is not uniform.By setting up mechanical mathematic model for the initiative roller of roller press,the non-uniformity mechanism of pole piece thickness has been figured out.To correct this disadvantage and promote the quality of the lithium battery,the proposal to improve the structure of traditional roller press has beendesigned,where the bearing seats and two sets of hydraulic cylinders with different forces will be installed at both sides of roller,a model and analysis for the optimized roller press via computer software Solidworkshave studied,from which we can work out the force applied on the hydraulic cylinder to ensure the minimun bending stress of the roller.Then set up design platform for pole piece of roller based on computer programming languages software to increase the speed to obtain related working parameters for optimized roller press.The experiment results have shown that the optimized roller press can make the thickness of lithium battery pole piece more uniform and greatly improve the automation level for the production of lithium battery.关键词
