Abstract
AbstractThe development of Lithium-ion (Li-ion) batteries has led to progress in the electronics, automobile and space applications sectors. At present lithium-ion battery is an essential part of Electric Vehicles (EVs) because of its inherent advantages such as high specific power, long battery life, low auto discharge rate, no memory effect and high nominal voltage. Most of the batteries generate large amount of heat during discharge phase and the operational temperatures significantly affects the efficiency and reliability of the batteries. Therefore, an efficient battery thermal management system (BTMS) is the need of the hour. The phase change material (PCM)-based BTMS is an effective and promising cooling strategy for better performance of Li-ion batteries. The PCM can absorb/release large amount of latent heat during the charge (fusion) /discharge (solidification) process, capable of maintaining relatively constant temperature of the battery system. Most PCMs have low thermal conductivity, leading to slow charging and discharge rates that can lead to rise in temperature of the system. Metal foam with high thermal conductivity can be used in conjunction with PCMs to amplify the thermal conductivity, thereby ensuring uniform temperature distribution across the cell and accelerate the melting processes. This comprehensive review paper mainly focusses on the research progresses, challenges and prospects of the PCM embedded metal foam-based BTMS. Major focus of this review is the study of PCMs used along with copper, aluminium and nickel metal foams for improving the thermal performance. Effects of porosity and pore density on heat transfer performance of various PCMs are elaborated. Finally, conclusions are drawn and recommendations highlighting the research gap in this area are presented.
