张驰咨询:锂电池导入六西格玛咨询降低电池容量衰减
2022-07-01 15:16:00 【张驰课堂】

众所周知,电池的循环寿命是有限的。当一个电池进入了“老龄”阶段,科学家们会将其性能弱化的现象命名为“容量衰减”。“容量衰减”现象表示的是随着电池被充电次数增多,电池容量逐渐减少的现象。一台手机在刚开始用时电量可以持续一整天,过两年后却只能支撑几个小时了,导致这样现象发生的原因就是容量衰减。
电池容量随库存时长而衰减,如何根治?
概括起来,通过3条路线下手:
1、从极片制作、装配、检测、入库、包装全流程入手,识别出40多个个疑似原因;
2、综合运用多重筛选工具筛选出12个疑似因素;
3、试验设计出场,针对钢带、合金粉、隔膜、注液量、放置时间等因子进行筛选及优化,最终目标达成。
这即是通过六西格玛的系统工具和严谨的试验设计方法,分析和优化了看不见摸不着的锂电池制造过程,否则解决问题无从谈起。
张驰老师常说,有流程的影子就有六西格玛改善的空间。
在制造行业,人们总是聚焦于优化产品的质量;而在服务行业,人们则是聚焦于客户关系。六西格玛对企业的用途总结如下:(减少成本、提高生产率、增加市场份额、保留顾客、缩短周期时间、减少缺陷、改变企业文化、改进产品/服务、提升企业综合竞争力等)
