摘要： A thermal energy storage device (100) is provided. The thermal energy storage device comprises a chamber (101) including storage material (102), which is configured to store thermal energy, and two or more ports (103, 104) configured to pass a flow (105) of heat transfer medium. The storage material is configured to exchange thermal energy with the heat transfer medium. The thermal energy storage device further comprises a cage structure (106) comprising one or more cages (107) that provide a boundary (110) between one of the ports and at least part of the storage material, wherein the cage structure comprises a filling material (108). Further, the cage structure is configured to be passable by the heat transfer medium.
