THERMAL ENERGY STORAGE MATERIALS

摘要

A thermal energy storage material (TESM) system (and associated methods) that reproducibly stores and recovers latent heat comprising i) at least one first metal containing material including at least one first metal compound that includes a nitrate ion, a nitrite ion, or both; ii) at least one second metal containing material including at least one second metal compound; and iii) optionally including water, wherein the water concentration if any is present is less than about 10 wt.%; wherein the TESM has a liquidus temperature, TL, from about 1000°C to about 2500°C; and wherein the TESM exhibits a heat storage density from 3000°C to 800°C of at least about 1 MJ/I; so that upon being used in a system that generates heat, at least a portion of the heat is captured and stored by the TESM and subsequently released for use, and the system is generally resistant to corrosion at temperatures of about 300°C.
