Enhancements in energy storage induced by latent heat have been demonstrated by using phase-change materials. However, these enhancements occur only at the melting points of the materials. In this study, we demonstrated the controllability of latent heat absorption/release in a certain temperature range. A wide endothermic plateau from 370 to 407 ¢XC for the Hitec salt was obtained by releasing the latent heat of alloy particles embedded in the salt. The alloy particle-doped salt was applied to a Stirling engine to demonstrate its effectiveness in enhancing the energy and power outputs of the engine. Compared to pure salt, the alloy particle-doped salt can enhance the engine's energy output by 21%. With the advantages of scalable synthesis and superior thermal properties, the alloy particles have potential applications in energy storage enhancement in various thermal energy systems. ? 2016.Latent heatSnxZn1-x/SiOx core-shell alloy particlesThermal energy storageTunable endothermic plateau[SDGs]SDG7journal article10.1016/j.nanoen.2016.02.0582-s2.0-84973163226https://www.scopus.com/inward/record.uri?eid=2-s2.0-84973163226&doi=10.1016%2fj.nanoen.2016.02.058&partnerID=40&md5=77d5c488ed82cb039b00d1b3f9deb92c
