Beschreibung
Zusammenfassung:	Provided are a nickel-cobalt-manganese cathode electrode material and a recovery method for a waste nickel-cobalt-manganese cathode electrode material. The recovery method includes: the waste nickel-cobalt-manganese cathode electrode material is crushed, to obtain a granular material; the granular material is used as a crystal seed, and a precipitation reaction is performed in solution containing a nickel source, a cobalt source and a manganese source, to obtain a nickel-cobalt-manganese precursor; and the surface of the nickel-cobalt-manganese precursor is coated with a lithium source, to form a new nickel-cobalt-manganese ternary cathode electrode material. The above recovery method may not only shorten the recovery process of the waste nickel-cobalt-manganese cathode electrode material, reduce the cost, but also improve the electrical properties such as the discharge capacity and cycle performance of the new nickel-cobalt-manganese ternary cathode electrode material.
