Single crystalline α-manganese dioxide (α-MnO2) nanowires as anode materials for lithium-ion batteries

Here, we present the facile synthesis and characterizations of Alpha-Manganese dioxide nanowires (alpha-MnO2 NWs) and their effective use as potential anode materials to fabricate Li-ion batteries. The alpha-MnO2 NWs were synthesized by a simple hydrothermal method, and their structural, morphological, and compositional characteristics were studied using a variety of techniques. To fabricate Li-ion batteries, the prepared alpha-MnO2 NWs served as an effective anode material, which demonstrated a reversible capacity of about 372 mAhg(-1) at a current density of 100 mAg(-1) for the first cycle, and it exhibited a discharge capacity of about 330 mAhg(-1) for the 60 cycles, according to the electrochemical experiments. Furthermore, the Coulombic efficiency of 99% after 60 cycles supported the good reversible charge-discharge behavior.
