Micrometric Growth of V2O5Hexagonal Nano-plates as an Active Material for Lithium Ion Battery Cathode Electrode

This manuscript reports the synthesis of V2O5 nanostructures using reflux method, without using additives such as surface reactants. The influence of reaction parameters like temperature and concentration on the growth of nanostructures have been investigated. It has been observed that the nanostructures are formed with a hexagonal nano-plate morphology, grown from a common core. The diameter o...

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...

Polarization Analysis Based on Realistic Lithium Ion Battery Electrode Microstructure Using Numerical Simulation

The performance of lithium ion battery (LIB) is limited by the inner polarization and it is important to understand the factors that affect the polarization. This study focuses on the polarization analysis based on realistic 3D electrode microstructures. A c++ software was developed to rebuild and mesh the microstructure of cathode and anode electrodes through Nano-CT and Micro-CT scanned image...
