Previous work reported from JPL has included characterization of eleetrode kinetics and alkali atom transport from electrodes including MO) W, WRhX, WPtX(Mn), in sodium AMTEC cells and vapor exposure cells; and Mo in potassium vapor exposure cells. [Williams, cl al., 1990a, 1991, 1992] These studies were generally performed in cells with small area electrodes (about 1 to 5 cm2), and device geom...

Capacitive desalination is a promising desalination technique. A novel fl ow-through electrode architecture utilizes a newly developed porous carbon material to achieve dramatic improvements in desalination rate and salt concentration reduction. Image depicts a capacitive desalination cell with a fl ow-through architecture. Capacitive desalination (CD) is a promising desalination technique as, ...

• Adsorbed-enzyme-mediated electrochemical processes are investigated via simulations. Potential dependent Michaelis constants explained. Four classes of voltammograms introduced to help understand current responses. Porous electrodes can create enhanced effective surface coverage and sensing ability. We present theory for electrolysis at electrode surfaces modified by a layer electroactive enz...

Title of Document: Ionics and Electrochemical Reactions in 1D and 3D Crosslinked Porous Electrodes Eleanor Idonia Gillette, Doctor of Philosophy, 2015 Directed By: Dr. Sang Bok Lee, Department of Chemistry and Biochemistry Lithium ion batteries are a critical component enabling many modern technologies, including portable electronics, hybrid electric vehicles and more. While interest in nanomat...

A three-dimensional model of a single-layer lithium-ion pouch cell is presented which couples conventional porous electrode theory describing electrochemical behavior with an energy balance de...

In this study, the internal resistance with the increasing of electrode thickness in a typical nanoporous carbon-based supercapacitor and their corresponding electrochemical performances were designed and investigated in detail. As for the carbon-based double electrode layer electrochemical system, electrochemical experiments greatly support the fact of nonlinear dependence and indicate that th...

Lithium-ion batteries (LIBs) are generally constructed by lithium-including positive electrode materials, such as LiCoO2, and lithium-free negative electrode materials, such as graphite. Recently, lithium-free positive electrode materials, such as sulfur, are gathering great attention from their very high capacities, thereby significantly increasing the energy density of LIBs. Though the lithiu...

In this article, three-dimensional (3D) microstuctured poly(3,4-ethylenedioxythiophene) (PEDOT)/reticulated vitreous carbon (RVC) composite electrodes with varying amount of PEDOT loadings were successfully prepared by electrochemical deposition method. The composites were characterized by Raman spectroscopy, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and cyclic volta...

The streaming potentials generated by the flow of both liquid and gas through either a Pyrex capillary tube or else an unconsolidated Pyrex porous medium were investigated. This mixture of distilled water plus nitrogen gas simulated wet steam but allowed experiments to be run at room temperature. Single-phase flow of distilled water alone resulted in a constant voltage-to-pressure drop ratio, W...
