Abstract

Hexagonal layered lithium nickel manganate nanowires (see Figure) are prepared in large amounts through a simple soft-chemical redox reaction of a LiMn0.5Ni0.5O2 precursor. The structure and chemical composition of the nanowires can be tailored by tuning the reaction conditions. The resultant multicomponent nanowires show promise as a cathode material for Li secondary batteries.
