Problems solved by technology

However, once the button-type shells represented by CR2032, CR2025, and CR2016 are packaged, it is difficult to disassemble them. If they are dismantled violently with pliers, it will cause permanent damage such as electrode pads being torn and materials falling off. Accurately diagnose and explore its failure mechanism

Abstract

The invention relates to the field of disassembly of energy storage devices, in particular to a method and a device for disassembling a portable button type electrochemical energy storage device. The disassembling device comprises the [-shaped support, the movable module, the fixed module and the rotating handle, and the disassembling device can be conveniently transferred inside and outside the glove box only through a small transition bin of the glove box. During disassembly operation, the button type energy storage device is arranged between the liftable pressure applying column and the pressure bearing column, the transmission screw rod is rotated by twisting the rotating handle, and the liftable pressure applying column is driven to press the negative electrode of the button battery and the electrode plate, the gasket, the elastic sheet and the like in the negative electrode into the lower outer circular ring by pressing the negative electrode, the gasket, the elastic sheet and the like downwards; and the positive pole shell is clamped at the top of the lower outer circular ring, so that the disassembly of the button type energy storage device is realized. According to the invention, the disassembly operation can be conveniently completed at low cost, the disassembly accuracy is good, the whole disassembly process can realize lossless and efficient taking-out of the electrode slice, time and labor are saved, and the disassembly efficiency in the failure analysis process of the energy storage device is effectively improved.

Description

technical field [0001] The invention relates to the field of dismantling energy storage devices, in particular to a method and device for dismantling a portable button-type electrochemical energy storage device. Background technique [0002] Under the background of energy crisis and environmental pollution, electrochemical devices represented by lithium-ion batteries and supercapacitors have become the mainstream energy storage devices developed in the 21st century. However, electrochemical energy storage devices may fail during production, transportation, use, or long-term storage, which may affect the performance and reliability of the device, or may cause the overall energy storage component to stop working or cause safety problems. These failure phenomena include capacity decay (diving), poor consistency, easy self-discharge, high and low temperature performance degradation, short cycle life, large internal resistance, abnormal battery pack voltage, gas production, liqui...
