文摘
- •
The prepared Li[Ni0.5Co0.2Mn0.3]O2 cathode material is modified via direct reaction with NH4VO3.
- •
Residual lithium impurities on the surface of the material are reduced.
- •
A lithium ion conductive Li3VO4 coating layer is formed on the surface.
- •
Trace amount of vanadium is doped into the structure lattice.
- •
Excellent performance of the modified material was proved by us.
