In comparison to other PCMs types, organic materials, notably PA wax is the most commonly adopted to manage the battery thermal energy since it has high chemical stability, high latent heat, low cost, and corrosion resistance. Their drawbacks include the fact that they are not thermally conductive, prone to leaks, and are flammable.
Each battery thermal management system (BTMS) type has its own advantages and disadvantages in terms of both performance and cost. For instance, air cooling systems have good economic feasibility but may encounter challenges in efficiently dissipating heat during periods of elevated thermal stress.
