本申请涉及一种锂电池回收再利用设备，涉及新能源电池回收的技术领域，其包括机架，放电装置，用于对待拆解的电池组进行放电 ；拆解装置，用于将放电完成后的电池组拆解为电池单体；检测装置，用于对电池单体的耗损程度进行检测；组装装置，用于对检测合格的电池单体进行拼接组装，重复利用。本申请通过利用检测装置对拆解装置拆解后的电池单体进行电容衰减测试，从而筛选出电容衰减较少符合再利用标准的电池单体，并使用组装装置将筛选出的电池单体进行重新的组装拼接，使之成为新的电池组，使得优良的电池单体得以直接进行再组装利用，改善性能优良的锂电池单体被直接粉碎回收造成资源浪费的问题。

This application relates to a lithium battery recycling and reuse equipment, which relates to the technical field of new energy battery recycling, including a rack, a discharge device, and a battery pack to be disassembled for discharge; Disassembly device for disassembling the discharged battery pack into individual battery cells; A detection device used to detect the degree of depletion of battery cells; Assembly device for splicing and assembling qualified battery cells for reuse. This application uses a detection device to conduct capacitance attenuation testing on the disassembled battery cells of the disassembly device, in order to select battery cells with less capacitance attenuation that meet the reuse standards. The selected battery cells are reassembled and spliced using the assembly device to form a new battery pack, allowing excellent battery cells to be directly reassembled and utilized, The problem of resource waste caused by the direct crushing and recycling of lithium battery monomers with excellent performance improvement.
