摘要
动力锂离子电池注液封装生产过程中,人工操作引起的二次污染是影响电池性能的主要因素,在满足电池生产环境的要求下对电池生产工艺进行了分析,引入了过渡仓的结构设计,提出一套全自动真空连续注液封装系统。根据设计要求和该系统的组成建立了系统工作原理图,论述了系统的工艺实现过程。过渡仓的设计实现了干燥、注液和封装等工序的连续性,对封装系统的研究显著改善生产条件和工艺过程,提高了设备的自动化水平,解决了电池生产过程中的二次污染问题。
Here, we addressed the problem of secondary pollution in liquid injection and packaging of power lithium ion battery on industrial scale. A novel automatic production line was developed, which is capable of contin- uously and automatically drying, injecting liquid and packaging the battery in low vacuum without exposure to the ambient environment. The vacuum production line mainly included the pumping units, vacuum chambers, workpiece conveyor belt, automatic control units and power supplies, etc. The three transition chambers, resembling the air-lock and pumped separately, were design to load/unload workpieces and to maintain continuous production in vacuum environment. The technical subjects involved in design optimization of the newly developed vacuum production line were tentatively discussed. We suggest that the continuous liquid injection and packaging of power Li-ion battery in low vacuum be a total solution to the secondary pollution.
