Free QuoteVolume 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.
By controlling the temperature of phase transition, thermal energy can be stored in or released from the PCM efficiently. Figure 1 B is a schematic of a PCM storing heat from a heat source and transferring heat to a heat sink.
Systems-level thermal control strategies using PCM thermal storage should consider more realistic heat inputs. The majority of prior work on PCM thermal storage focused on canonical thermal loads (step functions, constant ramp functions, steady heating).
Although device designs are application dependent, general design principles for improved thermal storage do exist. First, the charging or discharging rate for thermal energy storage or release should be maximized to enhance efficiency and avoid superheat.
The use of phase change materials as a TES system could be a practical solution due to high latent heat value, the constant temperature during the phase change, small volume variations, and low cost compared to other TES . Austria was reported to be the first country to use the foundation piles as underground heat exchangers (HEX) in 1984 .
PCMs have extensive application potential, including the passive thermal management of electronics, battery protection, short- and long-term energy storage, and energy conversion. In this work, we presented a comprehensive overview of PCM thermal storage at the multi-physics fundamental level, materials level, device level, and systems level.
