An apparatus comprises a single axle shredder device, a double axle shredder device, a variable frequency furnace, a first rotary device, a second rotary device, a crushing device, a first filtering, a second filtering, a transporting device, a sorting equipment, an extruding device, a separation equipment and a black mass collector. A method for recycling electronic components bearing lithium battery, includes: inputting first gas to a single axle shredder device and a double axle shredder device selectively, and to a variable frequency furnace, inputting electronic components with lithium battery to the single axle shredder device and the double axle shredder device selectively, tearing the electronic components with lithium battery into a plurality of pieces by the single axle shredder device and the double axle shredder device selectively, supplying the pieces to the variable frequency furnace via a channel and heating the pieces within the variable frequency furnace.

A method for recycling and treating an electrolytic solution of a lithium ion battery includes S1: cooling a fully discharged lithium ion battery below a freezing point of the electrolytic solution, and then disassembling and crushing the lithium ion battery to obtain a crushed solid containing the electrolytic solution, S2: under a protection of an inert gas, placing the crushed solid in a supercritical CO.sub.2 extraction instrument in which an entrainer is added; S3: conducting extraction; and S4: collection an extraction product with a cryogenic device, and adsorbing water in the extraction product using a 4 type lithiated molecular sieve, adsorbing HF in the extraction product using weak-base anion-exchange resin and adsorbing organic acid and alcohol in the extraction product using a 5 type lithiated molecular sieve.

In a method for recycling all solid-state batteries, spent battery cells are dissolved in anhydrous ethanol. The resulting solution is separated into solids and supernatants which are separately processed to regenerate the solid electrolyte and the solid electrode materials. The supernatant is subjected to vacuum evaporation to precipitate an electrolyte powder, which is then annealed under flowing oxygen. The solid electrode material is regenerated by washing the solids with water, drying the washed solids, relithiating the washed solids, and annealing the relithiated solids. The resulting materials are suitable for use in fabrication of new all-solid state batteries.

The crushing and classifying device of the present disclosure includes a crushing chamber into which an electrode material is inserted, a rotating shaft, a striking body, and a screen. The rotating shaft is disposed in the crushing chamber and rotates under a driving force. The striking body has a rod shape or a chain shape, and is rotatably connected at one end to the rotating shaft, and rotates in the crushing chamber by receiving a centrifugal force associated with the rotating of the rotating shaft. The screen is provided on a wall surface of the crushing chamber, and classifies the crushed electrode material. The striking body includes, at least at its distal end, an edge portion rounded to have a radius of curvature greater than or equal to 1 mm and less than or equal to 9 mm. The screen has an opening that is equal to or less than 5 mm.
