Receiving method.The concrete technical scheme of the present invention is as follows：
A kind of recovery method of ternary battery anode slice, the program of recovery is carried out in accordance with the following steps：
The first step, tertiary cathode piece is mixed with organic solvent, heating stirring, and control solution temperature is at 50 degrees Celsius to 60
Between degree Celsius.
Second step, by the solution by 10-100 mesh screen packs, and removes the aluminium film on filter screen.
3rd step, the filter cake containing tertiary cathode material is obtained by the filtrate of filter screen lower floor by filter press.
4th step, by above-mentioned filter cake in 600-900 DEG C of sintering.
Filter cake is taken out after 5th step, burn-up PVDF, conductive agent, you can obtain high-purity tertiary cathode material.
Preferably, the positive plate refers to that Surface mulch has the aluminium foil of nickle cobalt lithium manganate.
Preferably, the organic solvent is 1-METHYLPYRROLIDONE, acetone, or the solvent mixed of the two.
Beneficial effects of the present invention：Pass through the recovery to ternary battery anode slice so that the higher nickel cobalt mangaic acid of value ratio
Lithium is reused, and this method simple flow, with efficiently and energy-conservation the characteristics of.
