Review of Phase-Change Cooling Technology Research on Automotive Lithium-ion Batteries

From the perspective of phase change materials,the influence of the selection and preparation of phase change materials,the design of new cooling structure of phase change materials and the cooling system formed by phase change materials and other cooling methods on heat dissipation of lithium-ion batteries is reviewed,and the advantages and shortcomings of fin assisted phase change cooling,foam metal-assisted phase change cooling,and the heat dissipation system coupled with phase change materials and heat pipes are summarized.The analysis results show that optimizing the composition ratio of composite phase change materials,adding fins or foam metals to phase change materials can help dissipate heat.The heat dissipation system coupled with phase change materials and other cooling methods can not only achieve good heat dissipation effect,but also have a wide application potential through continuous optimization and improvement.
