This invention provides an ion-doped calcium oxalate thermochemical heat storage material and its preparation method, the chemical formula of which is Ca. 1‑ x M x C2O4·H2O, where M is a dopant ion and x is the mole fraction of the dopant ion; M includes Mg 2+ Co 2+ Zn 2+ 、Sr 2+ One or more of the following. This invention regulates the lattice parameters, local coordination environment, defect state, and microstructure of calcium oxalate by doping with ions. While maintaining the original reversibility and cycle stability of the calcium oxalate system, it further optimizes its dehydration thermal storage temperature range, thermal response boundary, structural evolution behavior, and application compatibility materials, thereby improving the thermochemical thermal storage performance of calcium oxalate from the internal structural level.

The application discloses a preparation method of a sulfide electrolyte layer, and specifically comprises the following steps: coating a mixed slurry including a sulfide electrolyte precursor, a lithium salt, a solvent and a binder on a pole piece to obtain a pole piece with a mixed slurry coating layer; the raw material A is a sulfide electrolyte or a sulfide electrolyte precursor; and the pole piece with the mixed slurry coating layer is dried to obtain a sulfide electrolyte layer attached to the pole piece. In the application, the preparation of the sulfide electrolyte and the coating process of the sulfide electrolyte are coupled, the preparation and modification of the sulfide solid electrolyte layer are simultaneously completed by using a pole piece drying process, the electrolyte is entirely in a liquid or slurry during the process, material preparation in a glove box is not needed, the material transmission and transfer are more favorable, the difficulty and cost of completely isolating water and oxygen from the powder material are greatly reduced, the production process is short, the process flexibility is strong, and the application is more favorable for industrialization.
