High efficiency separation of graphite and copper foil in the negative electrode of waste LITHIUM ion battery, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic iron removal recovery method. The separation and recovery method includes: providing a cleaning solution, which includes surfactants and water; Under the condition of ultrasonic application, cleaning solution is used to clean the separated lithium battery negative waste, so that the graphite in the lithium battery negative waste is separated from the copper foil, and the graphite is dispersed in the cleaning solution to form a mixed liquid, and the copper foil is separated from the mixed liquid. The graphite was extracted from the mixture.
Efficient separation of graphite and copper foil in the negative electrode of waste lithium-ion batteries PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC recovery method has high separation efficiency, up to 99%; No acid base and organic solvents are used, safe and environmentally friendly, graphite and copper foil can be separated efficiently under high liquid-solid ratio conditions, and the process is simple and the cost is low.
As a secondary negative electrode MATERIAL of LITHIUM ion PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC, the spherical fossil ink with excellent properties is output when removing iron. In the particle size distribution of spherical inks obtained by X-ray CT, the volume ratio of primary particles with equivalent sphere diameter below 0.8μm is below 40.0%, and that of primary particles with equivalent sphere diameter above 1.5μm and below 3.0μm is above 13.0%.
