Abstract
The invention discloses a preparation method of amorphous mono-crystalline precursor oxide and belongs to the technical field of lithium ion batteries. Amorphous ternary precursor hydroxide is prepared through a co-precipitation method; then amorphous ternary precursor oxide with a mono-crystalline shape is obtained through high-temperature thermal decomposition and the amorphous mono-crystallineternary precursor oxide is used as a novel lithium ion battery positive electrode material; the high-temperature circulating performance and the high-temperature rate performance of the lithium ion batteries can be effectively improved and a charging/discharging voltage platform of an existing ternary material is improved; the high-temperature safety, circulating and large-power charging/discharging properties of an existing lithium ion battery system are effectively improved; the invention provides the lithium ion battery positive electrode material with low manufacturing cost and good electric performance and defects of an existing lithium ion battery positive electrode material are made up; the problem that the capacity of the lithium ion battery positive electrode material is low is effectively improved.
