Research on Unevenness of Lithium Battery Pole Piece and Analysis on Structural Optimization of Roller Press

  • 摘要: 根据测量常规锂电池极片辊压过程后的厚度发现,极片厚度往往并不均匀。通过建立辊压机主动滚的受力数学模型,得出极片厚度不均匀机理。为改善这种现象,提高锂电池质量,提出对传统辊压机的结构优化改进,即在压辊两端安装轴承座与两组施力不同的液压缸。对优化后的辊压机进行Solidworks建模并进行优化分析,得到使压辊弯曲应力最小时应对液压缸的施力。并通过二次开发软件建立辊压极片的设计平台,可极大提高获取机构优化后的辊压机相关工作参数的速度。实验结果表明,优化后的辊压机可使锂电池极片厚度更为均匀,锂电池生产自动化水平度大幅提高。
