简介：In this work, anti-sintering Y2O3 was doped into CaO to prepare a novel composite for energy storage. Benefited from the homodisperse of Y2O3 in active CaO, which was proved by both SEM and TEM analysis, the novel composite exhibited high energy storage density and excellent cyclic stability. 35 wt.% is considered as the optimal addition amount of Y2O3 because of its highest energy storage density of 1986 kJ/kg after 10 cycles. CaY35 not only showed outstanding extended cyclic performance, but also maintained a satisfactory energy storage density of about 1400 kJ/kg under harsh calcination conditions due to its increased BET specific surface area and enriched porosity through the N2 adsorption analysis. In addition, extrusion-spheronization method was employed to granulate CaY35 powders into spherical pellets.
