Preparation method of ternary cathode material for aluminum battery

Abstract

The invention discloses a preparation method of a ternary cathode material for an aluminum battery. A first motor is driven, so that the first motor drives a stirring rotating rod to rotate; the stirring rotating rod drives a first clamping frame and a second clamping frame; the first clamping frame and the second clamping frame are driven to rotate in a mixing barrel; nickel salt, cobalt salt andmanganese salt are mixed and stirred with deionized liquid in the mixing barrel; meanwhile, when the stirring rotating rod rotates, a second fluted disc at the bottom of the stirring rotating rod isused for driving a first fluted disc, so that the first fluted disc drives a rotating sleeve rod, the rotating sleeve rod drives a rotating bottom plate, the rotating bottom plate rotates at the bottom of the mixing barrel, and meanwhile, the rotating sleeve rod drives a middle rotating plate. The mixing operation of the ternary cathode material preparation method is more uniform, the working efficiency is improved, meanwhile, the operation stability of the ternary cathode material preparation method is improved, and the blockage phenomenon is avoided.

Description

technical field [0001] The invention belongs to the technical field of preparation of ternary collection materials, and in particular relates to a preparation method of ternary collection materials for aluminum batteries. Background technique [0002] "Ternary material" refers to the whole material composed of three chemical components (elements), components (elements and compounds) or parts (parts), including alloys, inorganic non-metallic materials, organic materials, polymer composite materials, etc. Widely used in mineral extraction, metal smelting, material processing, new energy and other industries. [0003] The comparative document CN110492075A discloses a ternary material and a preparation method thereof, which relate to the field of electrode materials. The preparation method of the ternary material comprises the following steps: mixing manganese carbonate, cobalt hydroxide, nickel hydroxide and water in a weight ratio of 130 to 145 : 110~120: 350~365: 1700~1950 t...

Problems solved by technology

[0005] In order to overcome that when the user mixes and prepares the ternary collection materials through the traditional method, it is impossible to perform multiple mixing operations on the ternary collection materials, so that the ternary collection materials are prone to uneven mixing during the raw material mixing operation, which affects The processing quality of the ternary collection material; secondly, the traditional ternary collection material is prone to blockage during the discharge process, thereby interrupting the production of the ternary collection material and reducing the stability of the preparation method of the ternary collection material.
