Infiltrative coating of LiNi0.5Co0.2Mn0.3O2 microspheres with layer-structured LiTiO2: towards superior cycling performances for Li-ion batteries

Layer-structured LiTiO2 as a coating layer is built on the surface of ternary layered LiNi0.5Co0.2Mn0.3O2 microspheres using a facile infiltrative pre-coating approach. The uniform, nanoscale LiTiO2 coating layer doped with Ni2+ and Mn4+ ions strongly adheres to the host materials, which endows LiNi0.5Co0.2Mn0.3O2 microspheres with superior high-voltage cycling and thermal stability when used as cathode material for Li-ion batteries.
