Journal ArticleDOI
Diffusion of water in Nafion 115 membranes
TL;DR: In this paper, experimental and simulated data for the diffusion of water across Nafion membranes as a function of the water activity gradient are presented, and the model predictions are very sensitive to the value of the Fickian diffusion coefficient of water.
Journal ArticleDOI
Mathematical modeling of lithium-ion and nickel battery systems
TL;DR: A review of mathematical models of lithium and nickel battery systems developed at the University of South Carolina is presented in this article, where the ability of these models to predict reality is demonstrated by frequent comparisons with experimental data.
Journal ArticleDOI
An Electrochemical Route for Making Porous Nickel Oxide Electrochemical Capacitors
TL;DR: In this paper, the authors demonstrate the versatility of fabricating a wide range of porous metal oxide films using this electrochemical route for use in capacitor applications, including porous cobalt oxide films.
Journal ArticleDOI
Capacitance studies of cobalt oxide films formed via electrochemical precipitation
TL;DR: In this paper, it was shown that the charge storage in cobalt oxide was similar to that of nickel oxide, although their capacitances were different, and the material was shown to be inferior to nickel hydroxide/oxide when used as a positive electrode, it was seen to be superior as a negative.
Journal ArticleDOI
Studies on the Capacitance of Nickel Oxide Films: Effect of Heating Temperature and Electrolyte Concentration
TL;DR: In this paper, the mechanism of charge storage was studied by measuring the capacitance and surface area as a function of heating temperature and capacitance in different electrolytes and potential windows.
