Proton conductor electrolyte of solid oxide battery and preparation method of proton conductor electrolyte
The invention discloses a proton conductor electrolyte of a solid oxide battery and a preparation method thereof, and belongs to the technical field of solid oxide batteries, and the preparation method comprises the following steps: carrying out ball milling treatment on barium zirconate-based powder and an inorganic auxiliary agent, carrying out granulation treatment, adding an organic solvent, a plasticizer and a dispersing agent, adding an organic solution in which a binder is dissolved, and uniformly stirring; and carrying out tape casting, stamping and sintering treatment to obtain the finished electrolyte sheet. According to the preparation method, the organic tape casting process is expanded and applied to preparation of the barium zirconate-based proton conductor electrolyte membrane, and the mechanical strength gt can be obtained by accurately controlling the drying and sintering processes of the biscuit; the proton conductivity is gt under the conditions of 550 Mpa and 800 DEG C; the thickness of the proton conductor electrolyte thin film is accurately controllable between 30 microns and 1000 microns; the thickness of the proton conductor electrolyte thin film is 0.01 S/cm; meanwhile, the hot pressing process breaks through the limitation that the casting thickness is limited by the particle size of powder, and the casting thickness is successfully expanded to 1000 microns.
