Volume 2, Issue 8, 18 August 2021, 100540 Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.
The hybrid cooling lithium-ion battery system is an effective method. Phase change materials (PCMs) bring great hope for various applications, especially in Lithium-ion battery systems. In this paper, the modification methods of PCMs and their applications were reviewed in thermal management of Lithium-ion batteries.
Various modes of thermal energy storage are known. Sensible heat storage represents the thermal energy uptake owing to the heat capacity of the materials over the operational temperature range. In latent-heat mode, the energy is stored in a reversible phase transition of a phase change material (PCM).
The phase change composite material emerges great potential in thermal energy storage system. Lv et al. introduced CO 2 activated phoenix leaf biochar (CPL) into paraffin and SA to improve their thermal conductivity, and they measured the thermal conductivity of original PCM and composite PCMs by transient plane heat source method.
The heat absorbed and released during the phase transition is much larger than the sensible thermal energy storage. Generally, when a phase change material transforms from one phase state to another, a large amount of heat is absorbed or released in the environment. During phase change, the temperature remains basically constant.
Eutectic phase change materials with advanced encapsulation were promising options. Phase change materials for cooling lithium-ion batteries were mainly described. The hybrid cooling lithium-ion battery system is an effective method. Phase change materials (PCMs) bring great hope for various applications, especially in Lithium-ion battery systems.
