1. A thermochemical energy storage material, comprising:
a magnesium-transition metal spinel oxide that comprises magnesium manganese oxide; and
a dopant metal doping the magnesium-transition metal spinel oxide to enhance thermochemical energy storage, the dopant metal comprising at least one of iron (Fe) or nickel (Ni), and the dopant metal being a substituting material for manganese (Mn) in the magnesium-transition metal spinel oxide;
wherein the thermochemical energy storage material has the formula (MgMn1-xYx)3O4, where Yx represents the dopant metal, and a ratio of magnesium (Mg) to manganese (Mn) is 1:1 within a 15% tolerance.
