Recent Progress of Phase Change Materials Towards Battery Thermal Management Applications

It is of great significance to design an advanced power battery thermal management system for power battery. Among various system Phase Change Materials (PCM) cooling system has attracted extensive attention attributing to it’s simple in structure but having excellent performance. However, the defect of core materials PCM tightly restricted the industrial promotion of this emerging technology. Therefore, a minireview was written to summarize the modification strategies improving PCM’s essential properties i.e. thermal conductivity, shape collapsing and leakage concerns, as well as highly inflammable. Profound conclusions concerning about the prospect and challenges of PCM for thermal management applications were given. It was expected to provide some innovative ideas for the advancement of such capable technology.
