Synthesis of Hard Carbon- Silicon Nanocomposite as Anode Active Material for Lithium-Ion Batteries

In this research, using phenolic resin as the precursor of carbon and various amounts of ethylene glycol as a pore former, porous samples of hard carbon were synthesized. Samples were characterized by x-ray diffraction (XRD) and N2 adsorption-desorption methods. Broad diffraction peaks represent the amorphous structure of samples. Moreover, the gas adsorption-desorption curves showed that the a...

A unique hollow Li3VO4/carbon nanotube composite anode for high rate long-life lithium-ion batteries.

A unique hollow Li3VO4/CNT composite is synthesized via a facile method as an anode material in lithium batteries. Our work opens up the way for a promising material with high rate capability and good cycling stability due to its efficient Li(+) diffusion and relatively high structure stability.

Initial Discharge Capacity of Manganese Cobaltite as Anode Material for Lithium Ion Batteries

Nanostructured manganese cobalt oxide spinel (MnCo2O4) are prepared by co-precipitation method and calcined at 650 and 750°C. Morphological studies show that by increasing the calcination temperature from 650 to 750°C, morphology of the particles changes from quasi-plate to polyhedral. The MnCo2O4 calcined at 650°C could deliver an initial discharge capacity of 1438 mAh g-1 under current densit...

Hollow carbon nanospheres/silicon/alumina core-shell film as an anode for lithium-ion batteries

Hollow carbon nanospheres/silicon/alumina (CNS/Si/Al₂O₃) core-shell films obtained by the deposition of Si and Al₂O₃ on hollow CNS interconnected films are used as the anode materials for lithium-ion batteries. The hollow CNS film acts as a three dimensional conductive substrate and provides void space for silicon volume expansion during electrochemical cycling. The Al2O3 thin layer is benefici...
