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.

Carbon Coated

Carbon-coated, bismuth-doped, lithium iron phosphates, LiFe1xBixPO4(0x0.05), have been synthesized by a solid-state reaction method. From the optimization, the carbon-coated LiFe0.95Bi0.05PO4phase showed superior performances in terms of phase purity and high discharge capacity. The structural, morphological, and electrochemical properties were studied and compared to carbon-coated, LiFePO4. The Li/LiFe0.95Bi0.05PO4with carbon coating cell delivered an initial discharge capacity of 145 mAh/g and was 30 mAh/g higher than the Li/LiFePO4with carbon coating cell. Cyclic voltammetry revealed excellent reversibility of the LiFe0.95Bi0.05PO4with carbon coating material. High rate capability studies were also performed and showed a capacity retention over 93% during the cycling. It was concluded that substituted Bi ion play an important role in enhancing battery performance of the LiFePO4material through improving the kinetics of the lithium insertion/extraction reaction on the electrode.
