Description

Technical Field

[0001] The utility model relates to the technical field of soft-pack lithium batteries, in particular to an equipment for disassembling and recycling battery cores. Background Art

[0002] During the production process of soft-pack batteries, the stacked battery cores will be subjected to a short-circuit test, and some battery cores will short-circuit. The reasons for short-circuit are as follows: the current collectors of the positive and negative electrodes of the battery core are in contact with each other; the separator of the battery core is damaged, resulting in contact between the positive and negative electrode materials; the insulation performance of the separator of the battery core is poor, and short-circuit breakdown occurs during the test; there are micro-breakdowns of particulate dust in the battery core, etc. The positive and negative electrodes of these short-circuited battery cores can be recycled. The short-circuited battery cores will be disassembled by employees, the positive and negative electrode plates will be separated, and then put back into the electrode plate material box and returned to the laminator for lamination.

[0003] In automated equipment, after the short-circuited battery cores are picked out, employees will manually disassemble the battery cores and pick out the positive and negative electrode plates. Since the foil material of the positive electrode is aluminum foil and is relatively hard, it is basically not damaged when picked out. However, the foil material of the negative electrode is copper foil and is relatively soft, and it will be damaged when picked out. Therefore, basically the negative electrode cannot be used and can only be scrapped, and only the positive electrode can be recycled, which leads to a large amount of waste.
