[0002] In recent years, lithium batteries have been widely used in various portable electronic devices and electric vehicles due to their advantages such as high voltage, high specific energy, long cycle life, and good safety performance. As the cycle life of lithium batteries reaches its limit, a large number of waste lithium batteries have emerged. To prevent the serious damage to the environment caused by the careless disposal of metal elements such as cobalt, lithium, manganese, and nickel, as well as the fluorine-containing electrolyte contained in waste lithium batteries, it is necessary to recycle and harmlessly treat waste lithium batteries.

[0003] Because used lithium batteries often retain some charge, deep discharge of the remaining power is necessary to avoid potential safety hazards such as combustion and explosion during the disassembly and crushing of these batteries. Currently, the primary methods for discharging used lithium batteries are physical load discharge, puncture discharge, and chemical solution discharge. However, existing physical load discharge devices for used lithium batteries are complex to operate, inconvenient for batch discharge, and result in slow processing speeds and low efficiency. Therefore, there is an urgent need to address these shortcomings of the existing technology and provide a used lithium battery discharge device with a faster discharge processing speed.

[0030] In this embodiment, the through slot 8 is provided to facilitate the connection between the discharge assembly 7 and the discharge load 4 .

[0031] As a preferred embodiment, on the basis of the above structure, the discharge assembly 7 further includes a conductive rail 71, a conductive bar 72 and an electrode clamp 73. The two conductive rails 71 are fixed on the support frame 6 at a distance and extend in the left and right directions. The left and right ends of each conductive rail 71 are respectively fixedly connected to two conductive bars 72. The two conductive bars 72 at the same end of the two conductive rails 71 are respectively electrically connected to the two electrodes of the discharge load 4 located at the corresponding end. The two conductive rails 71 are correspondingly provided with multiple pairs of electrode clamps 73 for connecting the electrodes of the lithium battery body 10.

[0032] In this embodiment, two conductive rails 71 are used to facilitate the orderly placement of multiple lithium battery bodies 10 at the same time, thereby facilitating rapid discharge.
