Disassembling and recycling device and method for waste lithium battery

The embodiment of the invention discloses a disassembling and recycling device and method for a waste lithium battery. The disassembling and recycling device comprises a material bin provided with a containing cavity used for containing the waste lithium battery, and a gas storage bin communicated with one end of the material bin through a gas pipeline. The recycling mechanism is communicated with the other end of the material bin through an unloading mechanism which can be opened or closed, and the gas supply mechanism is used for supplying high-pressure gas to the material bin and the gas storage bin. A piston used for sealing and separating the containing cavity and the gas storage bin is arranged at the end, close to the gas storage bin, in the containing cavity, and the piston is movably arranged in the material bin. According to the method, the holes are formed in the waste lithium batteries in advance, then the holes are filled with the high-pressure gas for permeation, and further based on high-speed
