“…1,2 Therefore, the efficient use of low-grade waste heat can reduce energy consumption, which has been attracting much attention during recent decades. 3–5 Unfortunately, low-grade waste heat is difficult to recover and utilize due to its low exergy. 6 Thermal energy storage (TES) technologies are some of the most hopeful methods for realizing continuous and stable utilization of waste heat, 7 which is classified into three types: sensible, 8,9 latent 10,11 and thermochemical heat storage (TCS).…”
