The invention discloses a process for preparing a V2O3 / ZnV2O3 total battery by simultaneously using vanadium oxide in a zinc ion battery as a positive electrode material and a negative electrode material, which comprises the following steps: reacting ammonium metavanadate with absolute ethyl alcohol by adopting a solvothermal synthesis method, washing, drying, and calcining in a tubular furnace to obtain V2O3; in the preparation process of the V2O3 positive electrode material, only V2O3, acetylene black serving as a conductive agent and PVDF serving as a binder are mixed in proportion and then are coated on graphite paper, other coating protection materials do not need to be introduced into a V2O3 / Zn negative electrode, and V2O3 is used as a protection layer to inhibit growth of zinc dendrites, relieve hydrogen evolution side reaction of the zinc negative electrode and reduce corrosion of zinc. Vanadium oxide V2O3 is directly used as a core positive electrode material, the zinc negative electrode coating is developed by utilizing the characteristics of the vanadium oxide V2O3, a material is formed, meanwhile, the performance optimization of the positive electrode and the negative electrode is realized, the used raw materials are simple and easy to obtain, the process is simple and easy to implement, and the preparation process is simple and easy to implement from V2O3 raw material synthesis to positive and negative electrode piece preparation to V2O3 / ZnV2O3 total battery assembly. And comprehensive improvement of positive and negative electrode performances of zinc ions is simultaneously realized by a single material.

The utility model discloses foamed ceramic pressing equipment, and belongs to the technical field of foamed ceramics. The mold mainly comprises a mold body, an opening is formed in the top of the mold body, and a containing cavity is formed in the mold body; the pressing plate is hinged to the interior of the containing cavity, and one end of the pressing plate is connected with a first air cylinder; the gate is arranged on one side of the accommodating cavity; the sweeping mechanism is arranged on the side, away from the gate, in the containing cavity, the sweeping mechanism comprises a second air cylinder, the second air cylinder is fixedly installed on one side of the mold, and the output end of the second air cylinder penetrates through and extends into the containing cavity; the push plate is fixedly mounted at the output end of the second air cylinder; and at least two groups of scraping strips. According to the foamed ceramic pressing equipment, the sweeping mechanism is arranged, so that materials on the inner wall of the containing cavity can be removed while pressed foamed ceramic is discharged through the push plate, and the whole operation process is cleaner and more efficient.
