Speech topic: Application of reliability data analysis in lithium battery product development
summary:
This report will describe the application of data analysis in the development of lithium battery products, including the application in product design, development, production and maintenance. As a typical example of reliability data analysis, the quantitative analysis of the reliability of lithium battery products will be introduced: the product reliability assessment method based on failure physics. In practical applications, the failure state of a product can be encountered in the following situations. How to quantify and analyze to guide the design: 1) the degree of product performance degradation; 2) performance degradation or failure physics interpretation; 2) due to the limitations of fault diagnosis capabilities, the actual fault symptoms cannot be fully reproduced through analysis. JMP software will be used to illustrate the data collection, fault classification, fractional failure judgment, life distribution parameter estimation, reliability quantification and product field risk prediction for products at various stages, and demonstrate how to use JMP's reliability and survival modules to fit, model and predict the performance degradation caused by the main failure modes in the lithium battery market. For example, reliability modeling and failure rate prediction were carried out for the easy attenuation leading to insufficient battery life and the battery cell bulging leading to bulging.
