Zusammenfassung:	The invention discloses a preparation method of a high-nickel ternary NCM622-nanowire material. The method comprises the following steps: weighing certain amounts of a lithium source, a nickel source, a cobalt source and a manganese source according to a certain element mole ratio, adding the weighed sources into ethanol in order to a uniform and transparent solution; weighing a certain amount of polyvinylpyrrolidone, adding the polyvinylpyrrolidone into the above solution, and magnetically stirring the polyvinylpyrrolidone and the solution to completely dissolve the polyvinylpyrrolidone; weighing a certain amount of organic sugar used as a water absorption inhibitor into the above solution, and continuously stirring the organic sugar and the solution to completely dissolve the organic sugar; transferring the obtained solution into a syringe, carrying out electrostatic spinning, and receiving nano-fibers by aluminum foil; sintering the above obtained product in air; and carrying out high temperature calcinati
