What is the important method to solve the thermal runaway of power lithium-ion battery?

The improvement of cooling methods The thermal management system is mainly responsible for controlling the temperature to ensure that the battery is always at a reasonable operating temperature. Generally, the thermal management system is controlled by the vehicle controller. When the temperature of the battery pack is abnormal, the air-conditioning system will promptly dissipate heat or heat to ensure battery safety and life. Improvement of internal materials and structure. Internal improvement refers to the transformation of the internal material structure of the cell, so that the lithium-ion battery has better heat resistance and heat dissipation performance. In terms of current research hotspots, the development of solid electrolytes; structural transformation of the positive and negative electrodes; and introduction of safer separator materials are one of the mainstream methods to improve the thermal performance of batteries from within. With the development of lithium-ion batteries and the development of raw materials, the safety of lithium-ion batteries has made breakthroughs. Well-designed heat dissipation structure, battery protection circuit and management system are all conducive to improving the safety of lithium-ion batteries, so the safety problem of large-capacity power lithium-ion batteries is expected to be solved.
