The invention relates to a nickel cobalt manganese lithium oxide material used for an anode of a li-ion battery and a preparation method. The invention belongs to the li-ion battery technical field. The nickel cobalt manganese lithium oxide material used for the anode of the li-ion battery is a li-rich laminated structure with the chemical component of Li1+zM1-x-yNixCoyO2; wherein, z is less than or equal to 0.2 and more than or equal to 0.05, x is less than or equal to 0.8 and more than 0.1, and y is less than or equal to 0.5 and more than 0.1. The preparation method of the invention is that dissoluble salt of the nickel, cobalt and manganese is taken as the raw material; ammonia or ammonium salt is taken as complexing agent; sodium hydroxide is taken as precipitator; water-dissoluble dispersant and water-dissoluble antioxidant or inert gas are added for control and protection; in a cocurrent flow type the solution is added to a reaction vessel for reaction; after alkalescence disposal, aging procedure, solid-liquid separation and washing and drying, the nickel cobalt manganese oxide is uniformly mixed with the lithium raw material; the nickel cobalt manganese lithium oxide powder is obtained by sintering the mixed powder which is divided into three temperature areas. The invention has the advantages of high specific capacity, good circulation performance, ideal crystal texture, short production period, low power loss, and being suitable for industrial production, etc.
