Abstract
Layered and cathodes belonging to the solid solution series between and have been synthesized and characterized by charge-discharge measurements in lithium cells before and after modifying their surface with . The surface-modified cathodes show significantly lower irreversible capacity loss (ICL) and higher discharge capacity with excellent cyclability compared to the unmodified counterparts. For example, surface modified shows a remarkably high capacity of with an ICL of and good rate capability. This capacity value is much higher than that achieved with the previously known after similar surface modification .Keywords
