Early studies have shown a 92% reduction in the degree of supercooling with a 62% reduction in ice crystal size. A rather counter intuitive outcome considering that a reduced degree of supercooling is often associated with larger ice crystals at − 20 °C with 700 W, 2.45 GHz, and 60% duty cycle (Fig. 9) [ 118, 119 ].
The storing of electricity typically occurs in chemical (e.g., lead acid batteries or lithium-ion batteries, to name just two of the best known) or mechanical means (e.g., pumped hydro storage). Thermal energy storage systems can be as simple as hot-water tanks, but more advanced technologies can store energy more densely (e.g., molten salts ...
Thermal Energy Storage Materials (TESMs) may be the missing link to the "carbon neutral future" of our dreams. TESMs already cater to many renewable heating, cooling and thermal management applications. However, many challenges remain in finding optimal TESMs for specific requirements. Here, we combine literature, a bibliometric …
Energy Storage is a new journal for innovative energy storage research, covering ranging storage methods and their integration with conventional & renewable systems.

Abstract. The demand for cooling, such as that of products, spaces, and processes, has increased with the development of urbanization. Cold storage can shift the valley time of electric power to cold energy. Compared to the fixed cold storage routine, mobile cold storage can eliminate site limitations. Ice slurry, as a new functional fluid, has …
Ice slurry is a type of cold storage medium with the advantages of high-energy storage density, good fluidity and fast cooling rate, which has the prospect of wide application.

Energy storage under high-rate compression of single crystal tantalum. When a material is plastically deformed the majority of mechanical work is dissipated as heat, and the fraction of plastic work converted into heat is known as the Taylor-Quinney coefficient (TQC). Large-scale molecular dynamics simulations were performed of high …
Featured with high energy density and long lifespan, lithium-ion batteries (LIBs) are emerging as a key role in the electrochemical energy storage market. However, the limited abundance of lithium and the high cost of LIBs retards the progress of their further application[ 2, 3 ].
Antiferroelectric (AFE) HfO2/ZrO2-based thin films have recently emerged as a potential candidate for high-performance energy storage capacitors in miniaturized power electronics.
