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.

Surface modification on the electrode has a vital impact on lithium-ion batteries, and it is essential to probe the mechanism of the modified film on the surface of the electrode. In this study, a Li2O-2B2O3 film was coated on the surface of the cathode material by solution method. The cathode powders derived from co-precipitation method were calcined with various weight percent of the surface modified glass to form fine powder of single spinel phase with different particle size, size distribution and morphology. The thermogravimetry/differential thermal analysis was used to evaluate the appropriate heat treatment temperature. The structure was confirmed by the X-ray diffractometer along with the composition measured by the electron probe microanalyzer. From the field emission scanning electron microscope image and Laser Scattering measurements, the average particle size was in the range of 7-8µm. The electrochemical behavior of the cathode powder was examined by using two-electrode test cells consisted of a cathode, metallic lithium anode, and an electrolyte of 1M LiPF6. Cyclic charge/discharge testing of the coin cells, fabricated by both coated and un-coated cathode material, provided high discharge capacity. Furthermore, the coated cathode powder showed better cyclability than the un-coated one after the cyclic test. The introduction of the glass-coated cathode material revealed high discharge capacity and appreciably decreased the decay rate after cyclic test.
