| titleOfInvention | Preparation method of layered positive electrode material hybrid surface of lithium ion battery |
| abstract | The invention discloses a lithiumThe preparation method of the layered cathode material with the hybrid surface for the ion battery comprises the following steps: first, the precursor is placed in polyanion (XO) 4 ) nā In the (X ā P or Si) solution, since the polyanion and the transition metal ion solubility product constant Ksp are lower and the chemical reaction preferentially occurs on the surface of the precursor, a transition reaction from the hydroxide phase or the carbonate phase on the surface of the precursor to the polyanion phase occurs, and a precursor coated with the polyanion phase on the surface is obtained; then adding a lithium source with a metering ratio to ensure that the molar ratio of lithium to the transition metal Li/Ni-Co-Mn is (1+ z)/(1-z) - (1+ z)/(1-z) +0.05, and calcining at high temperature, wherein only 1.5 mol% of polyanion can be doped into the main body structure of the layered material due to the larger ionic radius of the polyanion, and the rest polyanion and lithium ions can form a fast lithium ion conductor phase Li on the surface of the layered material 3 PO 4 Or Li 2 SiO 3 Finally, surface polyanion (XO) is formed 4 ) nā The doped and fast lithium ion conductor coexists to form a layered cathode material for a lithium ion battery having a hybrid surface. |
