Title: Comments on the structural complexity of lithium-rich Li{sub 1+x}M{sub 1-x}O{sub 2} electrodes (M=Mn, Ni, Co) for lithium batteries.

Abstract

Structural features of lithium-rich Li{sub 1+x}[Mn{sub 0.5}Ni{sub 0.5}]{sub 1-x}O{sub 2} and Li{sub 1+x}[Mn{sub 0.333}Ni{sub 0.333}Co{sub 0.333}]{sub 1-X}O{sub 2} electrode samples (0 {le} x {le} 0.15), prepared in-house and by an industrial company, have been determined by powder X-ray diffraction, high-resolution transmission electron microscopy imaging, convergent beam electron diffraction and nuclear magnetic resonance. The results are discussed broadly in terms of the complexity of intergrown and disordered xLi{sub 2}MnO{sub 3} {center_dot} (1-x)LiMO{sub 2} systems, particularly when cobalt is combined with manganese and nickel in the transition metal layers of the LiMO{sub 2} component. It is proposed that the addition of trivalent cobalt to the transition metal layers in the Li{sub 1+x}[Mn{sub 0.333}Ni{sub 0.333}Co{sub 0.333}]{sub 1-x}O{sub 2} compounds at the expense of tetravalent manganese and divalent nickel reduces the amount and size of the Li{sub 2}MnO{sub 3}-like regions, rendering them essentially amorphous to X-ray diffraction.
