浅议锂离子电池辊压工艺对后续工艺及性能的影响

Effect of rolling process on subsequent process and performance of lithium ion battery

通过指导学生参加江西迪比科股份有限公司专业实习机会,分析了辊压工艺对锂离子电池的分条、制片、卷绕及注液等工序及电池容量、循环性能、内阻、安全性、电池一致性电性能的影响;提出优化辊压工艺、控制压实密度和极片反弹合理化建议。

By guiding students to participate in the professional practice opportunity of Jiangxi dibike Co.,Ltd.,the influence of rolling process on the slitting,production,winding and liquid injection of lithium-ion battery,as well as the battery capacity,cycle performance,internal resistance,safety,battery consistency and electrical performance is analyzed;The rationalization suggestions of optimizing rolling process,controlling compaction density and pole rebound are put forward.
