Abstract

The present application discloses a method for preparing a high-nickel cathode material for lithium-ion batteries and the high-nickel cathode material for lithium-ion batteries prepared therefrom, and specifically relates to the technical field of cathode materials for lithium-ion batteries. The method includes the following steps: (1) mixing a high-nickel ternary cathode material precursor, a lithium salt, a phosphorus-containing additive and a metal oxide additive; (2) loading mixed materials into a saggar, placing the saggar into a high-temperature and high-pressure device to conduct sintering, and after sintering, conducting natural cooling; and (3) grinding and sieving cooled materials to obtain the high-nickel cathode material for lithium-ion batteries. The present application has the beneficial effects of obtaining a high-nickel cathode material with a low residual lithium content, a low pH value and a low specific surface area by mixing the high-nickel ternary cathode material precursor, the lithium salt, the phosphorus-containing additive and the metal oxide additive in a specific proportion and conducting low-temperature sintering first and high-temperature sintering second, greatly simplifying process flows and reducing manufacturing costs.
