Abstract
Single crystalline lithium nickel manganese oxide ( LiNi 0.5 Mn 1.5 O 4) nanotubes have been prepared by a facile self-templating method from β- MnO 2 nanotubes. The wall thickness and hollow part of the nanotubes are around 250 nm and 200 nm, respectively. The tubular LiNi 0.5 Mn 1.5 O 4 exhibits good rate capability and high-rate cycling stability. At 10 C, it can yield a high discharge capacity of 99 mAh g-1. After 550 cycles at 5 C, a discharge capacity of 85 mAh g-1 can be kept, indicating a promising application in high-power Li -ion batteries.
