Zhang Chi Consulting: lead lithium battery into six sigma consulting to reduce battery capacity attenuation

as everyone knows , The cycle life of the battery is limited . When a battery enters “ ageing ” Stage , Scientists will name the phenomenon of weakening its performance “ Capacity attenuation ”.“ Capacity attenuation ” The phenomenon indicates that as the battery is charged more times , The gradual reduction of battery capacity . A mobile phone can last a whole day when it is first used , After two years, it can only last for a few hours , The reason for this phenomenon is capacity decay .

The battery capacity decays with the length of inventory , How to cure ？

Sum up , adopt 3 Take this route ：

1、 Made from pole pieces 、 assembly 、 testing 、 Put in storage 、 Start with the whole process of packaging , Identify 40 Many suspected reasons ;

2、 Comprehensively use multiple screening tools to screen 12 Two suspected factors ;

3、 The test design goes out , For steel strip 、 Alloy powder 、 The diaphragm 、 Liquid injection volume 、 Filter and optimize factors such as placement time , The final goal is achieved .

This is through six sigma system tools and rigorous experimental design methods , Analyzed and optimized the invisible and untouchable lithium battery manufacturing process , Otherwise, there is no way to solve the problem .

Teacher Zhang Chi often says , With the shadow of process, there is room for six sigma improvement .

In the manufacturing industry , People always focus on optimizing the quality of products ; In the service industry , People focus on customer relationships . The use of Six Sigma for enterprises is summarized as follows ：（ Cost reduction 、 Increase productivity 、 Increase market share 、 Retain customers 、 Shorten cycle time 、 Reduce defects 、 Change the corporate culture 、 Improve the product / service 、 Enhance the comprehensive competitiveness of enterprises ）
