Preparation device and preparation method of nickel-metal hydride battery solution

The invention discloses a preparation device and a preparation method of a nickel-metal hydride battery solution, and the preparation method comprises the following steps: 1, preparing an alkaline solution: weighing KOH, LiOH, potassium methoxide and water according to a ratio, and putting the materials into a preparation cylinder; 2, preparing an additive: weighing Na[Al(OH)4], zinc acetate and glycerol or ethylene glycol according to a proportion, and putting the mixture into a second accommodating cavity of the preparation cylinder 3, preparing electrolyte: mixing the alkaline solution and the additive, and preparing mixed liquor. According to the preparation device and method of the nickel-metal hydride battery liquor, the partition plate can be separated from the sealing groove, the effect that solutions in the first containing cavity and the second containing cavity circulate is achieved, and when circulation is synchronous, the electrolyte can be separated from the sealing groove; and under the driving
