Optimization of the Synthesis Procedure of LiMn2O4 Electrodes for Efficient Rechargeable Lithium Cells: Influence of the Crystallite Size and Surface Defects on the Electrochemical Performances of 3 V Li1+xMn2O4 and 4V Li1-xMn2O4 Electrodes
Electrochemical model Li batteries nanocrystalline materials
2010/12/10
Various LiMn2O4 electrode materials, having different crystallite sizes ranging from ∼50Å to ∼500Å, have been investigated either in 3V or in 4V Li batteries. In agreement with...
A New Method for the Preparation of Fine-Grained SnO2 and WO3 Powders: Influence of the Crystallite Size on the Electrochemical Insertion of Li+ in SnO2 and WO3 Electrodes
Fine-Grained SnO2 and WO3 Powders the Electrochemical Li+ SnO2 and WO3 Electrodes

We propose an unconventional method to obtain fine-grained SnO2 and WO3 powders. It uses as precursors, polymer complexes between polyethylene oxide (POE) and SnCl4 or WCl6 respectively. By pyrolysis ...
The Influence of Crystallite Size on the Apparent Basal Spacings of Kaolinite
Crystallite Size Apparent Basal Spacings Kaolinite
