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

Abstract

The invention relates to a battery pole piece photocatalytic degradation device and battery pole piece photocatalytic degradation equipment. The battery pole piece photocatalytic degradation device comprises a degradation container and a pole piece fixing frame, wherein the degradation container is used for containing a composite system containing a photocatalyst and water, and the pole piece fixing frame is used for being placed into the degradation container during degradation operation; and a fixing structure for fixing a battery pole piece is arranged on the pole piece fixing frame. The battery pole piece photocatalytic degradation device further comprises an oxygenating pipe for introducing oxygen-containing gas into the composite system, wherein the oxygenating pipe is provided witha gas inlet used for being connected with oxygenating equipment and a gas outlet used for being immersed into the composite system. The battery pole piece photocatalytic degradation device also comprises a light source used for illuminating the composite system so as to degrade organic matters in the pole piece. According to the technical scheme, the technical problems of high cost, low degradation efficiency and serious environmental pollution when the waste lithium battery is degraded in the prior art are solved.

Description

Technical field [0001] The invention belongs to the technical field of waste lithium ion battery recovery, and specifically relates to a battery pole piece photocatalytic degradation device and a battery pole piece photocatalytic degradation device. Background technique [0002] With the widespread application of lithium batteries, my country has become the world’s largest producer and consumer of lithium batteries. In particular, in recent years, the country has introduced a series of preferential policies such as purchase subsidies, tax reductions and exemptions, making the new energy vehicle market increasingly vigorous. 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 used power lithium batteries will exceed 12GWh, with a scrap volume of 170,000 tons. The electrolyte in a large number of waste lithium ba...
