Nanostructured electrode materials negative electrodes

Mesoporous tin was deposited from LLC surfactant phases in order to provide a nanostructured negative electrode material for applications in lithium ion batteries. Whitehead et al. [67,68] electrodeposited tin films from lyotropi-cally liquid crystalline solutions of tin sulfate in the hexagonal phase of Brij 76 onto copper foil. The authors further employed n-heptane as an inert swelling agent in order to tailor the dimensions of the resulting electrode materials. 

Carbon Nanostructures as Active Materials in Negative Electrodes.71... 

The first two parts of the chapter are dedicated to positive and negative materials, respectively, with a broad overview of the status of the R D specially oriented on nanomaterials optimization and nanostructuration effect. Then we will switch to some examples of practical performances and behavior of Li-ion cells using these new materials or nanostructured electrodes. 

How can such problems be counterbalanced Since a large capacitance of a semiconductor/electrolyte junction will not negatively affect the PMC transient measurement, a large area electrode (nanostructured materials) should be selected to decrease the effective excess charge carrier concentration (excess carriers per surface area) in the interface. PMC transient measurements have been performed at a sensitized nanostructured Ti02 liquidjunction solar cell.40 With a 10-ns laser pulse excitation, only the slow decay processes can be studied. The very fast rise time cannot be resolved, but this should be the aim of picosecond studies. Such experiments are being prepared in our laboratory, but using nanostructured... 

Very recentty, improvement in rate capability, capacity, and cycling behavior has been observed in the case of nanostructured titania, strengthening the possibility to use this oxide as a negative material for Li-ion batteries. Bruce and Lindsay have reported that the crystallite size and shape play key roles for improving the performances of the electrodes [22, 23], It also has to be noted that their investigation concerned either hydrothermal synthesized Ti02 nanotubes or anodic oxide thin...
