A lithium transition metal oxide material coated with a fast ion conductor and a preparation method therefor. The chemical formula of said material is (1-x)Li 1+a (Ni (1-m-n) Co n Mn m ) 1-b M b O 2 ·xLi c Al d Ti e M' f M" g (PO 4 ) 3 . A lithium transition metal oxide coated with a fast ion conductor has a low impedance, good cyclic performance, and good safety performance at a high voltage, especially when the charging voltage is greater than 4.62 V, 4.65 V, or a higher voltage. The lithium transition metal oxide can be obtained by sintering one time, and the lithium transition metal oxide material coated with a fast ion conductor can be obtained by sintering a second time. |
