摘要	Phase change materials (PCMs) show substantial promise in regulating the supply and demand of renewable energy and in recovering and utilizing waste heat. However, existing PCMs face challenges with spontaneous thermal energy dissipation and lack the ability of long-term heat storage and controlled release of thermal energy. In this study, we successfully predicted a class of Ni-Ti-Zr-Cu PCMs with high performance by using machine learning method, which can effectively recover low-grade waste heat, and has the characteristics of longterm thermal energy storage and stress-driven controlled thermal energy release. The experimental results show that the inverse martensitic transformation entropy is as high as 51.8 J kg- 1 K- 1. Under the uniaxial stress, martensitic transformation can be induced and adiabatic temperature change of 20K, resulting in an isothermal entropy change greater than 44.7 J kg- 1 K- 1. In addition, it has a high thermal conductivity of 12.68 Wm-1 K- 1 and a figure of merit (FOM) greater than 1300 x 106 (J2 K- 1 s- 1 m-4), an order of magnitude improvement over conventional PCMs. This work provides a new idea for designing long-term storage, long distance transmission and controlled release of PCMs.
