A process for producing a VO2-based heat-storage material, characterized by comprising a step (a) in which V2O5 is mixed with a carbon material and a step (b) in which the resultant mixture is heated in an inert gas atmosphere, the mixing proportion of the V2O5 to the carbon material in the mixing step (a) being in the range of 1:(0.41-0.54) in terms of the molar ratio of V2O5:(carbon atoms in the carbon material), and the heating temperature in the heating step (b) being above 900ºC but lower than 1,542ºC. Due to this, a process is provided by which a VO2-based heat-storage material having sufficient heat storage properties is easily mass-produced at low cost. |
