Problems solved by technology

At present, the conventional discharge method is to soak in salt solution for a long time. This discharge method has a long discharge time, which affects the recovery and treatment efficiency of waste lithium batteries, and also produces a large amount of waste water and waste gas, polluting the environment. Soaking the salt solution of lithium batteries Safe discharge is required after secondary treatment, which is prone to secondary pollution

Abstract

The invention discloses a dry-type discharge method and device for a waste lithium battery.A lithium battery and conductive sand are mixed and put into a conductive barrel, the conductive barrel is driven to rotate, the mixture of the lithium battery and the conductive sand runs from a feed port to a discharge port in the conductive barrel, and in the running process, the positive electrode and the negative electrode of the lithium battery are connected through the conductive sand to form a discharging loop, and heat generated in the discharging process of the lithium battery is discharged by the heat dissipation device of the conductive cylinder; and in the process of discharging the lithium battery through the conductive sand, wastewater, waste gas and other substances which pollute the environment cannot be generated, the conductive sand can be recycled, heat generated in the discharging process is discharged through the heat dissipation device, and potential safety hazards do not exist.

Description

technical field [0001] The invention relates to the technical field of lithium battery discharge, in particular to a dry discharge method for waste lithium batteries, and also to a discharge device related to the discharge method. Background technique [0002] Lithium batteries have the advantages of high energy density, long cycle life, and no memory effect. Since their commercialization, their usage has increased year by year. The average lifespan of lithium ions is 2 to 3 years, and the number of retired lithium batteries is also huge, and is currently increasing year by year. At the same time, lithium batteries contain toxic lithium hexafluorophosphate and various valuable metals, such as copper, aluminum, nickel, cobalt, manganese, etc. If the recycling is not handled properly, it will cause great harm to the environment and personal safety, and it will also be a great waste of resources. Therefore, the harmless recycling of lithium batteries is a necessary condition ...
