Can thermal energy storage materials revolutionize the energy storage industry?

Thermal energy storage materials 1, 2 in combination with a Carnot battery 3, 4, 5 could revolutionize the energy storage sector. However, a lack of stable, inexpensive and energy-dense thermal energy storage materials impedes the advancement of this technology.

What is a thermal energy storage material?

During discharge, the thermal energy storage material transfers thermal energy to drive the heat pump in reverse mode to generate power, as well as lower-grade heat that can be used in various other applications.

What are the different modes of thermal energy storage?

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).

Is Pei-BNNS a high-temperature energy storage material?

The results show that the obtained PEI-BNNS/PP- y wt % HfO 2 /PEI-BNNS composite (abbreviated as BHB- y) is a promising high-temperature energy storage material. BHB-3 achieves the highest Ud of 12.01 J/cm 3 and η of 91.05% at a high temperature (150°C).

Does nanocomposite have high-temperature energy storage capacity?

The nanocomposite’s high-temperature energy storage ability was greatly enhanced by precisely regulating the ratio of BT to BNNS. The Ud of the nanocomposite reached 2.92 J/cm³, and the BDS was 547 MV/m at 150°C. Compared with pure PEI, they were increased by 83% and 25% respectively.

What are the energy storage parameters of the BHB composite?

In addition, the whole energy storage parameters of the BHB composite—which was created by concurrently loading the BNNSs onto PEI and HfO 2 nanoparticles onto the PP layer in the PPP composite—were further enhanced to a great extent. In particular, its Ud value increased by two times compared with PEI, and the η value remained above 90%.
