A Review on Thermal Management of Li-ion Battery:from Small-Scale Battery Module to Large-Scale Electrochemical Energy Storage Power Station

Li-ion battery is an essential component and energy storage unit for the evolution of electric vehicles and energy storage technology in the future.Therefore,in order to cope with the temperature sensitivity of Li-ion battery and maintain Li-ion battery safe operation,it is of great necessary to adopt an appropriate battery thermal management system(BTMS).In this paper,the current main BTM strategies and research hotspots were discussed from two aspects:small-scale battery module and large-scale electrochemical energy storage power station(EESPS).The practical application situation,advantages and disadvantages,and the future development trend of each heat dissipation method(air,liquid,PCM,heat pipe,hybrid cooling) were described in detail.Among them,the air cooling and liquid cooling were reviewed in-depth based on the engineering application.The PCM,heat pipe and hybrid cooling were reviewed extensively based on the latest explorations.The research provides a comprehensive understanding for the BTMS in all scales.
