Preparation method and use of high-performance modified lithium-nickel- manganese-cobalt oxide (lnmco) nickel 55 material

Abstract

The present disclosure discloses a preparation method and use of a high-performance modified lithium-nickel-manganese-cobalt oxide (LNMCO) nickel 55 material. In the preparation method of the present disclosure, a silica template-containing nano-precursor coated with a polymer is prepared by electrospinning, and then the nano-precursor is sintered in the air to effectively provide effective embedding and attachment sites for subsequent nickel plating; and after the nickel plating, the silica template is removed such that distributed mesopores are generated in situ on the precursor. The mesopores provide channels for the subsequent penetration of molten lithium into the interior of the precursor material. A final prepared material has a better ion and electron conduction structure compared with traditional granular materials. The present disclosure also discloses a material prepared by the method. The present disclosure also discloses an LIB including the high-performance modified LNMCO nickel 55 material.
