Abstract

MnO/C core–shell nanorods were synthesized by an in situ reduction method using MnO₂ nanowires as precursor and block copolymer F127 as carbon source. Field emission scanning electron microscopy and transmission electron microscopy analysis indicated that a thin carbon layer was coated on the surfaces of the individual MnO nanorods. The electrochemical properties were evaluated by cyclic voltammetry and galvanostatic charge–discharge techniques. The as-prepared MnO/C core–shell nanorods exhibit a higher specific capacity than MnO microparticles as anode material for lithium ion batteries.
