Battery pole piece photocatalytic degradation device and battery pole piece photocatalytic degradation equipment

Abstract

The invention relates to a photocatalytic degradation device for a battery pole piece and photocatalytic degradation equipment for a battery pole piece. The battery pole piece photocatalytic degradation device includes a degradation container for holding a composite system containing photocatalyst and water and a pole piece holder for putting into the degradation container during the degradation operation. The pole piece holder is provided with a The fixed structure of the battery pole piece is fixed, and the photocatalytic degradation device for the battery pole piece also includes an oxygenation tube for introducing oxygen-containing gas into the composite system. The oxygenation tube is provided with an air inlet for connecting with the oxygenation equipment and The gas outlet for sinking into the composite system, the battery pole piece photocatalytic degradation device also includes a light source for illuminating the composite system to degrade the organic matter in the pole piece. The above technical solution solves the technical problems of high cost, low degradation efficiency and serious environmental pollution in the prior art when degrading waste lithium batteries.

Description

technical field [0001] The invention belongs to the technical field of recycling waste lithium ion batteries, and in particular relates to a photocatalytic degradation device for battery pole pieces and photocatalytic degradation equipment for battery pole pieces. Background technique [0002] With the widespread application of lithium batteries, my country has become the largest producer and consumer of lithium batteries in the world. Especially in recent years, the country has introduced a series of preferential policies such as purchase subsidies and tax reductions, which have made the new energy vehicle market increasingly vigorous. As a new The "heart" of energy vehicles, the power lithium battery industry is also developing rapidly, followed by a large number of scrapped power lithium batteries. It is estimated that by the end of 2018, my country's accumulated waste power lithium batteries will exceed 12GWh, and the amount of scrapped power lithium batteries will reach 1...
