Problems solved by technology

Although these preparation methods can adjust the structure of porous materials to a certain extent and solve the leakage problem of phase change materials, they ignore the function of the metal material itself and its adjustment and enhancement of the carbon structure, and the carbon material used has a single function. The preparation method is cumbersome, which limits its application
