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...

Electrochemical behavior of LiCoO2 as aqueous lithium-ion battery electrodes

Despite the large number of studies on the behavior of LiCoO2 in organic electrolytes and its recent application as a positive electrode in rechargeable water battery prototypes, a little information is available about the lithium intercalation reaction in this layered compound in aqueous electrolytes. This work shows that LiCoO2 electrodes can be reversibly cycled in LiNO3 aqueous electrolytes...

Electrochemical characterization of a polypyrrole/Co0.2CrOx composite as a cathode material for lithium ion batteries

Polypyrrole/Co0.2CrOx, (PPy/Co0.2CrOx) composites were synthesized by polymerizing pyrrole onto the surface of cobalt chromium oxide (CrOx) in acidic media. The PPy/Co0.2CrOx composites increase the reversible capacity of the electrochemically active material up to 20%. At C/10 rate, a reversible capacity of 215 mAh/g was obtained for PPy/Co0.2CrOx composite, compared to 178 mAh/g for the virgi...

A high performance lithium-ion battery using LiNa0.02K0.01FePO4/C as cathode material and anatase TiO2 nanotube arrays as anode material

In this paper we report on a lithium ion battery (LIB) based on improved olivine lithium iron phosphate/carbon (LiFePO4/C) as cathode material and LiNa0.02K0.01FePO4/C  synthesized by sol-gel method and TiO2 nanotube arrays (TNAs) with an anatase phasesynthesized through anodization of Ti foil as an anode electrode. Crystallographic structure and surface morphology of the cathode and anode mate...

Concentration-Dependent Chemical Expansion in Lithium-Ion Battery Cathode Particles

In this work, the effect of the concentration-dependent chemical-expansion coefficient, b, on the chemo-elastic field in lithium-ion cathode particles is examined. To accomplish this, an isotropic linear-elastic model is developed for a single idealistic particle subjected to potentiostatic-discharge and charge conditions. It is shown that b can be a key parameter in demarcating the chemo-stres...
