AI Technical Summary

Technical Problem

Existing lithium-ion battery electrode recovery devices easily cause material compaction during high-temperature calcination and decomposition, affecting the separation and recovery effect, and generating waste gas that pollutes the environment, making the working environment uncomfortable.

Method used

A waste electrode recycling device is designed, which includes a rewinding roller, a wiping box, a cleaning box and a drying box. The coating is physically removed by the wiping box, cleaned by the cleaning box and dried by the drying box, avoiding high-temperature treatment and realizing the recycling of copper and aluminum foil.

Benefits of technology

It achieves efficient recycling of copper and aluminum foil, avoids waste of resources, improves the comfort of the working environment, and reduces environmental pollution.

Abstract

The utility model discloses a waste pole piece recovery device which comprises an unwinding roller, a wiping box, a cleaning box, a drying box and a winding roller which are sequentially built, a pole piece is led out by the unwinding roller and sequentially passes through the wiping box, the cleaning box and the drying box, and at least two wiping rollers are carried in the wiping box and used for wiping the two sides of the pole piece respectively; a cleaning roller group settled in a cleaning solvent is carried in the cleaning box, so that the pole piece on the cleaning roller group is cleaned in the cleaning solvent; a drying roller set used for drying the pole piece is carried in the drying box, and the pole piece passes through the drying roller set and then is led out to the wind-up roller. According to the utility model, coating and metal separation is carried out on waste pole pieces or coated copper-aluminum foils, so that the copper-aluminum foils are recycled, and the recycling rate of the foils is improved; high-temperature pyrolysis is not needed, and the working comfort is effectively improved.
