Fire Retardant Phase Change Materials-Recent Developments and Future Perspectives.The accumulation of thermal energy in the form of latent heat of phase transition using phase change materials (PCMs) is one of the most attractive and studied research areas with huge application potential in both passive and active technical systems.  In many applications such as building, battery thermal management, and protective insulations, the crucial task is to reduce the fire risk of flammable PCMs.  In the last decade, numerous research works have been performed to reduce the flammability of organic PCMs, without losing their thermal performance.
