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...

Electrochemical Evaluation of PbO Nanoparticles as Anode for Lithium Ion Batteries (Technical Note)

PbO nanoparticles were synthesized using hydrothermal process. Scanning electron microscopy (SEM) was used in order to investigate of PbO powders. X-ray diffraction (XRD) pattern confirmed β-PbO formation during this process. The crystallite size of the powders was calculated using Scherrer formula about 74.6 nm. Electrochemical evaluation of the PbO nanoparticles as anode for Li-ion batteries ...

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...

TiNb2O7 nanoparticles assembled into hierarchical microspheres as high-rate capability and long-cycle-life anode materials for lithium ion batteries.

As a competitor for Li4Ti5O12 with a higher capacity and extreme safety, monoclinic TiNb2O7 has been considered as a promising anode material for next-generation high power lithium ion batteries. However, TiNb2O7 suffers from low electronic conductivity and ionic conductivity, which restricts the electrochemical kinetics. Herein, a facile and advanced architecture design of hierarchical TiNb2O7...
