Synthetic process and equipment for calcium zincate as zinc-nickel battery negative electrode material

The invention relates to the technical field of calcium zincate synthesis and discloses a synthetic process for calcium zincate as a zinc-nickel battery negative electrode material. The synthetic process comprises the following steps of 1, mixing zinc oxide with organic acid, performing full reaction, performing filtering to remove impurities, then adding a certain quantity of strong alkaline solution, and performing mixing reaction to form a zincate solution; 2, (1) performing reaction on the organic acid and calcium hydroxide to produce an organic acid calcium solution, then dropwise addinga dispersant to form a mixed solution; or (2) adding the calcium hydroxide in a certain quantity of water, then dropwise adding the dispersant to form suspension liquid; 3, mixing products prepared instep 1 and step 2; 4, transferring reaction liquid obtained in step 3 into an ageing groove, performing still standing for 2-48 h, then performing centrifugal treatment, washing and drying filter residues, and performing crus
