Preparation method of barium sulfate for storage battery, barium sulfate based on barium sulfate and application of barium sulfate

The invention discloses a preparation method of barium sulfate for a storage battery, barium sulfate based on the barium sulfate and application, and belongs to the technical field of chemical material preparation. The water solution with the sulfate ion content of 1.8-2.0 mol/L is subjected to heat preservation under the condition that the temperature is larger than or equal to 80 DEG C, a sulfate ion solution is obtained, the water solution with the barium ion content of 0.9-1.0 mol/L is subjected to heat preservation under the condition that the temperature is larger than or equal to 80 DEG C, and a barium ion solution is obtained. And adding a barium ion solution into the sulfate ion solution in a stirring state, reacting and curing under the condition that the rotating speed is 20-40r/min, and washing and pickling precipitates to obtain barium sulfate. According to the method, the barium sulfate can be ensured to have good dispersity without adding a modifying agent or a dispersing agent. Impurities in b
