Embodiment

[0019] Embodiment: A kind of preparation method of charged state β-phase nickel oxyhydroxide adopts the following steps:

[0020] Weigh 5gNi(OH) 2 Dissolve in 5--10mol / L sodium hydroxide solution, the solution temperature is 40--100°C, then slowly add 100--500ml of sodium hypochlorite aqueous solution with a specific gravity of 1.19, and add 0.3--0.5g of oxidized Sub-cobalt, stir at a constant speed under the condition of 500--1500 revolutions per minute, use nickel plate or graphite (carbon) as the cathode and anode plate in the reaction tank, and perform electrolysis reaction at 0.05--0.5mA per square centimeter, and the reaction time is 2 --8 hours, then set aside to settle for 12--36 hours, filter, wash with 40--100°C deionized water, repeat several times until no alkali is tested, and finally, dry in vacuum at 50--90°C to prepare into a charged state β-phase nickel oxyhydroxide material.

[0021] The β-phase nickel oxyhydroxide prepared by the present invention is made ...

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 [0003] The pu...
