Equipment for separating current collector of lithium ion battery from active material on current collector

Abstract

The invention relates to equipment for separating a current collector of a lithium ion battery from an active material on the current collector. The equipment for separating the current collector of the lithium ion battery from the active material on the current collector comprises a processing tank, wherein a scraper type conveyer belt is arranged at the lower part of the processing tank; an active material peeling device is arranged at the upper part of the processing tank; the scraper type conveyer belt comprises a horizontal conveying section and an inclined discharge section which is arranged in an inclined manner; the horizontal conveying section corresponds to the active material peeling device vertically; meshes through which the current collector cannot passing but the peeled active material can pass are formed in the body of the scraper type conveyer belt; a collecting cabin for collecting the active material which passes through the meshes is arranged below the scraper type conveyer belt; a partitioning structure is arranged between the collecting cabin and the space above the scraper type conveyer belt; a discharge hole is formed in the lower part of the collecting cabin. By adopting the equipment, separation of the current collector of the lithium ion battery from the active material and the separated collection of the current collector and the active material are conveniently achieved, so that large-scale industrial production is achieved, and environment-friendly effect is achieved.

Description

Technical field [0001] The present invention relates to a device for separating a current collector of a lithium ion battery and an active material thereon. Background technique [0002] With the large-scale application of lithium-ion batteries, more and more lithium-ion batteries are scrapped. The main part of the lithium ion battery is the cell, and the main part of the cell is the pole piece, and the positive and negative poles of the pole piece mainly include the current collector and the active material coated on the current collector. Cost occupies a large proportion of the overall cost of lithium-ion batteries. Therefore, the separation and recovery of current collectors and active materials have considerable economic and social benefits. The current recycling process generally integrates the active material and the current collector through pole piece crushing and high-temperature melting, and then purifies the various metals in it; or through the battery pole piece crus...

Problems solved by technology

However, the above-mentioned equipment needs to be equipped with a separate recovery tank, and the recovery tank needs to be frequently transferred during operation, which is inconvenient to operate, low in efficiency, poor in safety, and high in cost, and the discharge of rare earth slag is realized by blowing the gas blowing pipe at the bottom of the treatment tank , the structure is complex, so it is not conducive to the realization of industrialized large-scale production, and cannot adapt to the increasing demand for recycling
