Abstract

The invention discloses a rapid discharging device of waste square batteries and a discharging method and relates to the technical field of waste battery discharging. The rapid discharging device is composed of a heat exchange groove and a battery bracket arranged above the heat exchange groove; the heat exchange groove is internally filled with metal conducting particles; the battery bracket is composed of a plurality of battery placement frames which are used for reversing the batteries; reversed battery pole columns are in contact with the metal conducting particles. The discharging deviceis simple in structure and low in processing cost; discharging operation is simple and feasible; compared with a sodium chloride solution immersion method, the discharging environment is remarkably improved and the discharging safety is improved.

Description

Technical field: [0001] The invention relates to the technical field of waste battery discharge, in particular to a rapid discharge device and a discharge method for waste square batteries. Background technique: [0002] Compared with traditional lead-acid batteries, nickel-metal hydride batteries, nickel-cadmium batteries, etc., lithium-ion batteries have the characteristics of high voltage, high discharge capacity, no memory effect, and zero pollution to the environment. They have been widely used in life and industry. With the wide application of lithium-ion batteries, a large number of waste lithium-ion batteries are produced, making the disposal of waste lithium-ion batteries a very important task. Lithium-ion batteries are energy storage devices, and there will still be a certain amount of residual power after they are scrapped. If the positive and negative electrodes are short-circuited due to improper disassembly, accidents such as explosions and fires may occur. ...
