Abstract: Lithium-ion battery heat dissipation difficulties seriously affect the efficient and stable operation of electronic devices and electric vehicles. Faced with the increasing heat dissipation demand, traditional liquid cooling systems cannot ensure the quality of heat dissipation and are seriously limited in the ability to provide uniform temperature adjustments. Combining microchannels with PCMs is beneficial. For the hybrid system here described, the maximum and average values of the temperature field were 10.35 K and 1 K, respectively, surpassing those of a liquid cooling system. By introducing suitable PCMs, the maximum value could be reduced by 5.6 K (under a 2C discharge rate) and by 16.2 K (under a 3C discharge rate). This article briefly introduces the development status and main problems of the technology combining microchannels and PCMs in BTMSs, then reviews the research progress for lithium-ion battery heat dissipation achieved by using the technology coupling microchannels and PCMs, analyzes its performance advantages, and finally prospects the future development direction of the microchannel–PCM coupling technology.
