Description

technical field [0001] The present application belongs to the technical field of battery heat dissipation, and particularly relates to the application of spray-type phase change materials in batteries and batteries. Background technique [0002] With the rapid development of social economy and science and technology, people have gradually realized the seriousness of the crisis of energy shortage and environmental pollution, especially the problem of global warming caused by the massive emission of greenhouse gases. [0003] Among them, as the daily transportation of human beings, traditional fuel vehicles are not only an important component of fossil energy consumption, but also one of the main sources of greenhouse gas emissions. New energy vehicles are an effective way to reduce fossil energy consumption and alleviate environmental pollution. As the core of pure electric vehicles, the thermal safety of power batteries restricts the development of pure electric vehicles. T...
