Summary: | The invention discloses a phase change energy storage low-melting-point alloy with high energy storage density and high conductivity and a preparation method thereof. The phase change energy storage low-melting-point alloy with high energy storage density and high conductivity comprises the following components in percentages by weight: 15.6-16.8% of Sn, 11.9-13.3% of In, 17.8-19.3% of Pb, 6.9-8.2% of Cd, 42.5-45.3% of Bi and 0.3-0.9% of graphene-plated copper powder. The preparation method comprises the following steps: vacuumizing; pressurizing, electrifying and smelting; and heating in a water bath and clamping a material. According to the low-melting-point alloy material obtained by the invention, the liquid phase heat conductivity reaches 58W/mK above which is over doubled compared with that of a liquid alloy phase change material and is far higher than that of a conventional phase change material.
