Analysis of the primary method to solve the thermal runaway of power lithium battery

Advances in cooling methods The thermal management system is primarily responsible for controlling the temperature to ensure that the battery is always at a reasonable operating temperature. Usually, the heat management system is controlled by the vehicle controller. When the temperature of the battery pack is abnormal, the air-conditioning system performs timely heat dissipation or heating to ensure the safety and life of the battery. Improvement of internal data and structure. Internal improvement is to transform the internal data structure of the battery cell, and then make the lithium battery have better heat and heat dissipation functions. In terms of current research hotspots, the development of solid electrolytes; structural transformation of the positive and negative electrodes; and the introduction of safer barrier materials are one of the main methods to improve the thermal function of the battery from the inside. Following the development of lithium batteries and the development of original materials, the safety of lithium batteries has developed breakthroughs. Well-planned heat dissipation structure and battery maintenance circuit and management system are all conducive to improving the safety of lithium batteries, so the safety problem of large-capacity power lithium batteries is expected to be solved.
