- Nano-sized lithium manganese oxide (LMO) dispersed on carbon nanotubes (CNT) has been synthesized
successfully via a microwave-assisted hydrothermal reaction at 200 C for 30 min using MnO2-coated
CNT and an aqueous LiOH solution. The initial specific capacity is 99.4 mAh/g at a 1.6 C-rate, and is maintained
at 99.1 mAh/g even at a 16 C-rate. The initial specific capacity is also maintained up to the 50th
cycle to give 97% capacity retention. The LMO/CNT nanocomposite shows excellent power performance
and good structural reversibility as an electrode material in energy storage systems, such as lithium-ion
batteries and electrochemical capacitors. This synthetic strategy opens a new avenue for the effective and
facile synthesis of lithium transition metal oxide/CNT nanocomposite.
