Research lithium batteries correctly

　　This article has a high reference value for further research on the temperature field of lithium-ion batteries and how to better control the thermal safety issues generated during the use of lithium-ion batteries.

　　The research on the temperature field distribution during the charging and discharging of lithium-ion batteries and how to better study and control the work of lithium-ion batteries mainly include the following aspects: 　　 1. Understand the development trend of lithium-ion batteries and some problems in their applications , In particular, has a clearer understanding of the heating problems and the safety risks caused by the abuse of lithium-ion batteries. 2. Through various ways, learn and research theoretical knowledge, understand the classification, characteristics, working principle and composition materials of lithium-ion batteries, understand the heating mechanism of lithium-ion batteries, and provide a theoretical basis for the temperature field analysis of lithium-ion batteries . 3. Combined with the knowledge of heat transfer, combined with the relevant knowledge of finite element, according to the actual application process, the working process of the physical lithium-ion battery and the heat problems encountered are abstracted, regularized, and formulated, and initially selected A general, of course, is the thermal mathematical model of the Li-ion battery after proper assumptions and simplified processing.　　4. Focused on the research and analysis of some related knowledge of finite element, and conducted a certain study of ANSYS through books, which provided a means for thermal analysis. 5. Using ANSYS to analyze the temperature field of a single lithium ion battery with two common shapes, and make a preliminary analysis of the defective lithium ion battery, and on the basis of the analysis, how to control the production process of the battery The issue of thermal safety put forward his own ideas.　　 In short, this article has a high reference value for further research on the temperature field of lithium-ion batteries and how to better control the thermal safety issues generated during the use of lithium-ion batteries.
