Preparation of Porous MnO@C Core-Shell Nanowires as Anodes for Lithium-Ion Batteries

Abstract

Porous MnO@C core-shell nanowires were prepared via a simple and facile method. The morphologies, the phase purity, the mass contents, and the BET surface area of the composite were characterized by SEM, XRD, TGA, and N2adsorption test, respectively. When the composite served as an anode for lithium-ion batteries, it showed superior electrochemical performances. The MnO@C composite presented a reversible capacity of 448.1 mAh g−1after 100 cycles at the current rate of 200 mA g−1.
