Analysis of The Lithium-ion Battery Safety & Stability Test-Part 1
With the continuous advancement of energy technology, the use of electric vehicles has become a viable solution to environmental problems. Compared with other types of batteries, lithium-ion batteries have the advantages of high energy density, long cycle life, easy use and maintenance, etc., and have become the first choice for power batteries for electric vehicles. However, the potential accident hazard of lithium-ion batteries will endanger the safety of people’s lives and property, and the confidence of consumers in accepting electric vehicles will be discouraged. Lithium-ion batteries are generally safe under normal conditions of use, but in the case of individual defects in the production process, and misuse or abuse conditions such as high temperature, short circuit, overcharge and discharge, vibration, extrusion and impact, etc. In the use of the battery will occur a thermal reaction to produce a large amount of heat, if it can not be diffused in time will cau...
