MnO/CNTs Composite as Anode Material for Lithium Ion Batteries

Article Preview

Abstract:

Transition metal oxaides especially manganese monoxide (MnO) are being intensively studied as candidate anode materials for next generation lithium ion batteries in high efficiency energy storage applications. In this paper, MnO/CNTs composite is prepared by hydrothermal reaction and subsequent annealing process. The results of XRD and SEM showed that MnO/CNTs composite is rod-like with good crystallinity, and its diameter is about 300 nm. It could deliver a reversible charge capacity of 689.6 mA h g-1 at the current density of 14.4 mA g-1, and the specific discharge capacity is 500.5 mA h g-1 after 185 cycles. All the above makes MnO a promising anode material for lithium ion batteries with high capacity, long life time, low cost and environmental benignity.
