    Abstract：In order to prepare the cement-based energy storage materials with excellent performance，study the effect of three kinds of energy storage phases，such asgraphite，carbon black and iron oxide black on the mechanical properties，thermal properties and endothermic properties of the samples. Finally，the mechanism of the mechanical properties of the samples affected by energy storage was explained. Considering that the contents of graphite，carbon black and iron oxide were 25%，8% and 25% respectively，the samples had excellent mechanical properties，thermal properties and endothermic properties. The factors that affect the mechanical properties are：carbon black>graphite>iron oxide black，and the factors that affect the endothermic performance are：graphite>carbon black>iron oxide black.
