The invention discloses a conductive
solid heat storage material and a preparation method thereof, and relates to the technical field of
solid heat storage and
energy storage. Mixing the pretreated steel
slag with a conductive filler; and carrying out multi-particle-size grading on the mixed particles, uniformly mixing, sequentially carrying out
compression molding and high-temperature
sintering treatment on the compound steel
slag, and cooling to obtain the steel
slag-based
solid heat storage material. A small amount of conductive filler is added into the steel slag, the
conductivity of the steel slag is effectively improved, the steel slag serves as a resistance
heating element and a heat storage medium at the same time, heating and heat storage functions are integrated, and therefore the heat storage
system structure is simplified, the energy efficiency is improved, the cost is reduced, and high-value utilization of steel slag solid waste is achieved.
