Abstract: Disclosed is an apparatus for efficiently pretreating and recycling a waste battery, which includes a bottom plate, a recycling device, a conveying device and a treatment device, and one end of a top portion of the bottom plate is fixedly mounted with a bottom portion of the conveying device. According to the invention, by arranging a fixing assembly and the recycling device, a suction pump can suck a slurry and an electrolyte in a battery downwardly for dropping, and a driving assembly can rapidly convey the slurry and the electrolyte in the battery to the treatment device for treatment at the same time.

Abstract: 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 CO2 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.

Abstract: Disclosed is a method for preparing a graphene-based sodium ion battery negative electrode material, including adding graphene oxide into ethanol absolute, carrying out ultrasonic treatment at a certain temperature to obtain a graphene oxide alcohol dispersion, then preparing a sodium hexanitritocobaltate solution, adding the graphene oxide alcohol dispersion into the sodium hexanitritocobaltate solution, carrying out solid-liquid separation to obtain a solid, isolating the solid from oxygen for calcination, and washing and drying to obtain a graphene-based sodium ion battery negative electrode material.
