Description

Technical Field

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. Their safety, specific capacity, self-discharge rate and performance-price ratio are all better than lithium ion batteries. When processing waste lithium batteries, it is usually necessary to discharge the remaining electricity in the lithium battery first. When discharging lithium batteries, they are usually poured directly into sodium chloride solution. After the treatment is complete, the lithium batteries need to be manually fished out of the solution.

[0003] Placing waste lithium batteries in sodium chloride solution is a chemical discharge method, which mainly uses the positive and negative metals of the battery as the cathode and anode to consume the residual power in the battery through an electrolysis process in the sodium chloride solution. This method is simple and feasible, and does not produce secondary pollutants, so it is widely used when discharging waste lithium-ion batteries.

[0004] Referring to CN216980673U, a waste lithium battery discharge device comprises a bottom plate, a support column is welded on the top of the bottom plate, a top plate is welded on the top of the support column, a transmission mechanism is arranged at the bottom of the top plate, a connecting frame is welded on the bottom of the transmission mechanism, and a loading box is connected to the surface of the connecting frame by bolts. The utility model has the advantages of convenient fishing and drying functions by setting a servo motor, a screw rod, a threaded block, a hydraulic rod, a connecting frame, a discharge battery, a magnetic field generator, an ultrasonic generator, a drying box, a jet plate, a connecting pipe, a heating wire and a fan. It solves the problem that when performing lithium battery discharge treatment, the lithium battery is usually directly poured into a sodium chloride solution. After the treatment is complete, the lithium battery in the solution needs to be fished out manually, which increases the workload of the staff. After the lithium battery is fished out, the surface is relatively wet, which is not convenient for subsequent treatment.

[0005] However, the following problem still exists: when the equipment is drying lithium batteries, the bottom layer of lithium batteries is not easy to dry, resulting in a longer drying time and inadequate drying. Utility Model Content
