Hybrid cooling systems, which integrate two or more battery cooling systems, are currently of great interest among researchers to reduce the possibility of thermal runaway because of the high demand for more energy density and shorter recharge time in batteries [24], [25], [26], [27].
Solid–solid PCMs, as promising alternatives to solid–liquid PCMs, are gaining much attention toward practical thermal-energy storage (TES) owing to their inimitable advantages such as solid-state processing, negligible volume change during phase transition, no
However, as the energy density of battery packs increases, the cooling efficiency of air cooling is insufficient to meet the heat dissipation requirements [11]. PCM utilizes the physical property of phase change, absorbing and releasing heat during the solid–liquid phase transition, which expands the limitations of active heating/cooling [13].
Compact liquid cooling strategy with phase change materials for Li-ion batteries optimized using response surface methodology
The results show that the addition of CPCM improves the heat dissipation of the battery. Ye et al.

3.2: Energy of Phase Changes
Melting and solidification have been studied for centuries, forming the cornerstones of PCM thermal storage for peak load shifting and temperature stabilization. Figure 1 A shows a conceptual phase diagram of ice-water phase change. At the melting temperature T m, a large amount of thermal energy is stored by latent heat ΔH due to the …
Solid-state batteries are considered as a reasonable further development of lithium-ion batteries with liquid electrolytes. While expectations are high, there are still open questions concerning the choice of materials, and the resulting concepts for components and full ...
A review of thermal management for Li-ion batteries
The cooling structure of a battery pack and coupled liquid cooling and phase change material (PCM) were designed in a thermal management system to enhance the cooling performance and extend the service life of lithium-ion battery packs. Numerical simulations were conducted based on the finite volume method. This study focuses on …
In recent papers, the phase change points of solid-solid PCMs could be selected in a wide temperature range of −5 °C to 190 °C, which is suitable to be applied in …
