Electrolytic preparing method for high-energy alkaline primary cell anode material

Abstract

The invention related to method for preparing hydroxy-nickel oxide includes following steps: dissolving nickel chloride in deionized water and preparing electrolyte; adding the said electrolyte into electrobath with inert material being as electrode; adjusting pH value and carrying out electroanalysis step; taking hydroxy-nickel oxide on anodic plate off, through cleaning, drying, milling and sieving steps to obtain hydroxy-nickel oxide. Comparing with procedure of using nickel hydroxide, the invented method possesses advantages as follows: low cost, high efficiency, with no wastewater treatment, carrying out reaction system in closed cycle, and availability of equipment for producing manganese dioxide.

Description

technical field

[0001] The invention relates to a chemical power source material, in particular to a method for preparing a high-energy alkaline primary battery cathode material nickel oxyhydroxide. Background technique

[0002] The continuous development of portable electronic products has put forward new requirements for the batteries used in them, especially the ever-emerging popular digital products have put forward higher requirements for batteries. When digital cameras first came out, most models used alkaline manganese batteries, but when alkaline manganese batteries were used in digital cameras that required high-power discharge, the discharge voltage would drop sharply, and it would be impossible to use only about 10% of the capacity. Work. As a result, the batteries used in digital cameras are transferred from alkaline manganese batteries to nickel-metal hydride rechargeable batteries and lithium-ion rechargeable batteries. However, Ni-MH rechargeable batteries a...
