Preparation method of charged state beta-phase nickel oxyhydroxide

Abstract

This invention discloses a method for preparing charging beta phase hydroxyl nickel oxide, applying NiOH after oxidation to prepare with uniform liquid phase method and select chloros as the main oxidant, attching electric field action the same time as the chemical oxidation to deeply oxidate the beta phase hydroxyl nickel oxide particles quickly in the electric field to form charging beta phase hydroxyl nickel oxide to be used as the nickel / zinc battery positive material with high discharging platform voltage.

Description

technical field

[0001] The invention relates to a method for preparing a positive electrode material of a zinc-nickel primary battery-charged state beta-phase nickel oxyhydroxide. Background technique

[0002] As we all know, the battery is an indispensable consumer product in our country's national economy and people's daily life. It provides portable energy for various electronics, communications, information and other products. However, with the continuous emergence of some new electrical appliances, the demand for high-current and heavy-duty batteries is becoming more and more urgent. Although the materials and structure of alkaline manganese batteries are constantly improving, their performance has also improved. However, in new digital cameras and smart toys In use, it can no longer meet the requirements. For this reason, a kind of zinc-nickel primary battery suitable for high-current work has been brought up on the agenda. Contents of the invention
