| description | The invention discloses a preparation method of nano silver chromate in the field of lithium batteries. The method comprises the following steps: preparing 20-40ml of 0.05-0.10 mol/L K2CrO4 solution,pouring the solution into a beaker, sealing by using a preservative film, and stirring by using a magnetic stirrer; after stirring is finished, putting the obtained mixed solution into ultrasonic equipment for ultrasonic treatment for 5-10 minutes, keeping an ultrasonic state, uncovering the preservative film, adding an AgNO3 solution with the concentration of 0.05-0.10 mol/L into the solution, continuing ultrasonic treatment, covering the preservative film after ultrasonic treatment is finished, standing to obtain a product, centrifugally separating the product, washing the separated product,and drying the product in a vacuum drying box to obtain a final nanometer silver chromate sample. Compared with the prior art, the gram specific capacity of silver chromate is improved by more than 30% after nanocrystallizati |
