Abstract

The invention is applicable to the sintering field of lithium battery positive electrode material, A slurry dry, comminuted and sinter integrated device is provided. the stirred positive electrode material slurry can be dried in turn, grind and sinter, cooling, etc. operation, A slurry scrape drying chamber and a hot bellows are inclined, so that the hot bellows can be dried more quickly and uniformly, A slurry scrape drying chamber is provided with a scraping plate, the slurry can be spread on the inclined plate more quickly under the action of certain gravity, after the slurry is dried, theslurry is scraped up by a pushing block and pushed to a pulverizing device, the pulverized dry slurry falls into a sintering tray and then enters a sintering chamber for sintering, After the sinteringis finished, the hot gas of the sintering chamber and the hot gas of the cooling chamber can flow directly into the hot blast box for recycling, and the drying, crushing, sintering and cooling processes of the whole slurry can be carried out and completed in the same device, so that the continuous automatic production can be realized, the production efficiency is remarkably improved, and the manual operation intensity is reduced.

Description

technical field [0001] The invention belongs to the field of sintering of positive electrode materials of lithium batteries, and in particular relates to an integrated device for drying, pulverizing and sintering slurry. Background technique [0002] Due to the important advantages of high voltage and high capacity, long cycle life and good safety performance, lithium-ion batteries have broad application prospects in portable electronic equipment, electric vehicles, space technology, defense industry, etc. High-energy lithium-ion One of the key technologies of batteries is the development of high-performance cathode materials. In lithium-ion batteries, the performance of cathode materials largely affects the performance of lithium-ion batteries and directly determines the cost of batteries. When preparing surface-modified or surface-coated positive electrode materials, it is generally necessary to go through the processes of positive electrode material slurry preparation, sl...
