Abstract
The present application discloses a lithium-manganese-nickel-containing composite oxide and a preparation method therefor, a positive electrode plate, a battery, and a power consuming device. The lithium-manganese-nickel composite oxide is in a spinel crystal form, and the ratio of the peak intensity I111 of the (111) peak to the peak intensity I400 of the (400) peak in an X-ray diffraction pattern of the lithium-manganese-nickel composite oxide is 2.1≤I111/I400≤3.3, wherein the diffraction angle of the (111) peak is 2θ=18°-19.5°, and the diffraction angle of the (400) peak is 2θ=43.5°-45°. In the above manner, the technical solution of the present application can improve the stability of the positive electrode active material, thereby improving the overall performance of the battery.
