Determination of Li(+) diffusion coefficients in the LixV2O5 (x = 0 - 1) nanocrystals of composite film cathodes.

The Li(+) ion diffusion coefficients (DLi+) in V2O5 (2.12 × 10(-12) cm(2) s(-1)) and in the intermediate α-, ε-, and δ-LixV2O5 phases (1.6 × 10(-14), 8.

Effect of interfacial oxides on the electrochemical activity of lead dioxide film electrodes on a Ti substrate.

The electrochemical activities of PbO(2) thin-film electrodes were systematically studied with an oxygen-transfer reaction, i.e., the oxidation of thiourea.

Simultaneous multimode experiments for studies of electrochemical reaction mechanisms: demonstration of concept.

An instrumental setup has been configured for a simultaneous real time recording of electrochemical, spectroelectrochemical, and mass data on an electrode from a single measurement for studies of complex electrochemical reaction mechanisms. This was achieved by combining a few pieces of equipment: a potentiostat/galvanostat for electrochemical measurements, the near-normal incidence reflectance spectrometer for spectroelectrochemical measurements, and a quartz crystal analyzer (QCA) for mass changes on the electrode. The latter two were coupled through a bifurcated optical fiber on the reflective QCA electrode.
