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

Abstract

Here, we present the facile synthesis and characterizations of Alpha-Manganese dioxide nanowires (α-MnO2 NWs) and their effective use as potential anode materials to fabricate Li-ion batteries. The α-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 α-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.
