Lithium ion power battery metal casing impurity removal method

一种锂离子动力电池金属外壳的除杂方法

Abstract

The invention relates to a lithium ion power battery metal casing impurity removal method. Before the casing assembling process of a lithium ion power battery, a metal casing of the battery is immersed in alkali liquor, the inner wall and the outer wall of the metal casing are fully immersed for a period of time, then the metal casing is taken out, and is washed by clear water and is dried, and the dried metal casing is applied to a subsequent production process of the lithium ion power battery. According to the invention, the metal casing of the lithium ion power battery is cleaned through alkali liquor, the fraction defective of lithium ion batteries can be greatly reduced, the lithium ion power battery metal casing impurity removal method can be operated easily, conveniently and quickly, and the lithium ion power battery metal casing impurity removal method can effectively adapt to large scale production processes of lithium ion power batteries.
本发明涉及一种锂离子动力电池金属外壳的除杂方法,在锂离子动力电池进行入壳装配工序前,将电池的金属外壳置于碱液中浸泡,使得该金属外壳的内壁和外壁充分浸润一段时间,然后拿出该金属壳用清水冲洗并干燥,将干燥好的该金属外壳应用于锂离子动力电池的后续生产工序中。本发明通过碱液对锂离子动力电池的金属外壳进行清洗,可以大大降低锂离子电池的不良率,该法操作简单易懂,方便快捷,可以有效的适应锂离子动力电池的大规模生产过程。
