This book was released on 2021 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing demand for sustainable energy production and safer electronics necessitates electrochemical energy storage devices with improved capacity and operating range. Ionic liquids (ILs) and deep eutectic solvents (DESs) are emerging electrolytes that remove the limitations of traditional solvents for energy storage. ILs have wide electrochemical windows, are often more thermally stable than organic electrolytes, and have negligible vapor pressure. DESs are easily synthesized from inexpensive components and are being considered for the next iteration of flow batteries. While both ILs and DESs fit into their own place amongst energy storage devices, they share a similar need in that the key interfaces governing electrochemical phenomena are poorly understood. We have begun determining the underlying interactions which govern the phenomena at both the solvent-solute and electrode-electrolyte interface in ILs and DESs. Electrochemical and spectroscopic investigations of an organic redox species in DES and DES analogues demonstrate faster diffusion of holes compared to diffusion of the solvation - complex. Less significant differences between hole and solvation-complex diffusion are observed for the systems where the Raman spectra of the organic species shift to lower energies. Determining differential capacitance of DESs indicates that strong hydrogen bonding hinders interfacial ion accumulation and extends the potential profile. For ILs we have shown that cations with ringed structures lead to larger overall capacitance while free alkyl chains allow for greater increases in ion density. Furthermore, it has become clear that ion density at the IL - electrode interface is strongly dependent upon local steric and repulsive forces and not bulk ion interaction strength. Complementing the trends in ion density, surface enhance Raman spectroscopy (SERS) captures potential induced rotations of the anion in and out of the electrode plane as well as buckling of large alkyl chains on the cation. Complementary to SERS, neutron reflectometry captures diffuse layers of ions where the composition between layers alternates from anion to cation rich.
Book Synopsis Electrolytes at Interfaces by : S. Durand-Vidal
Download or read book Electrolytes at Interfaces written by S. Durand-Vidal and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to provide the reader with a modern presentation of ionic solutions at interfaces, for physical chemists, chemists and theoretically oriented experimentalists in this field. The discussion is mainly on the structural and thermodynamic properties, in relation to presently available statistical mechanical models. Some dynamic properties are also presented, at a more phenomenological level. The initial chapters are devoted to the presentation of some basic concepts for bulk properties: hydrodynamic interactions, electrostatics, van der Waals forces and thermodynamics of ionic solutions in the framework of a particular model: the mean spherical approximation (MSA). Specific features of interfaces are then discussed: experimental techniques such as in-situ X-ray diffraction, STM and AFM microscopy are described. Ions at liquid/air, liquid/metal and liquid/liquid interfaces are considered from the experimental and theoretical viewpoint. Lastly some dynamic (transport) properties are included, namely the self-diffusion and conductance of small colloids (polyelectrolytes and micelles) and the kinetics of solute transfer at free liquid/liquid interfaces.
Book Synopsis Electrified Interfaces in Physics, Chemistry and Biology by : R Guidelli
Download or read book Electrified Interfaces in Physics, Chemistry and Biology written by R Guidelli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrified interfaces span from metaVsemiconductor and metaVelectrolyte interfaces to disperse systems and biological membranes, and are notably important in so many physical, chemical and biological systems that their study has been tackled by researchers with different scientific backgrounds using different methodological approaches. The various electrified interfaces have several common features. The equilibrium distribution of positive and negative ions in an electrolytic solution is governed by the same Poisson-Boltzmann equation independent of whether the solution comes into contact with a metal, a colloidal particle or a biomembrane, and the same is true for the equilibrium distribution of free electrons and holes of a semiconductor in contact with a different conducting phase. Evaluation of electric potential differences across biomembranes is based on the same identity of electrochemical potentials which holds for a glass electrode and which yields the Nernst equation when applied to a metal/solution interface. The theory of thermally activated electron tunneling, which was developed by Marcus, Levich, Dogonadze and others to account for electron transfer across metaVelectrolyte interfaces, is also applied to light induced charge separation and proton translocation reactions across intercellular membranes. From an experimental viewpoint, the same electrochemical and in situ spectroscopic techniques can equally well be employed for the study of apparently quite different electrified interfaces.
Book Synopsis Electrical Double Layer at a Metal-dilute Electrolyte Solution Interface by : G.A. Martynov
Download or read book Electrical Double Layer at a Metal-dilute Electrolyte Solution Interface written by G.A. Martynov and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the properties of a metal-electrolyte interface, even the spe cific nature of an electrode reaction, proneness of a metal to cor rosion, etc., are primarily determined by the electrical double layer (EDL) at this boundary. It is therefore no surprise that for the last, at least, one hundred years intent attention should have been centered on EDL. So much of material has been gathered to date that we are easi ly lost in this maze of information. A substantial part of the attempts to systematize these facts is made at present within the framework of thermodynamics. Such a confined approach is undoubtedly inadequate. The Gouy-Chapman theory and the Stern-Grahame model of the dense part of EDL developed 40-70 years ago, tailored appropriately to suit the occasion, inevitably underlie any description of EDL. This route is rather too narrow to explain all the facts at our disposal. A dire necessity has thus arisen for widening the principles of the micros copic theory. This is precisely the objective of our monograph. Fur thermore, we shall dwell at length on the comparison of the theory with experiment: without such a comparative analysis, any theory, however elegant it may be, is just an empty drum.

This book includes five high-quality papers that can lead to technological developments in electrochemical capacitors. The first paper describes the effect of the milling degree of activated carbon particles used in the electrodes on the supercapacitive performance of an electric double-layer capacitor. The second, fourth, and fifth papers describe novel electrode materials that have the potential to enhance the performance of next-generation electrochemical capacitors. Nickel molybdate/reduced graphene oxide nanocomposite, copper-decorated carbon nanotubes, and nickel hydroxide/activated carbon composite are tested, and are shown to be promising candidates for next-generation electrochemical capacitors. The third paper reports the hybrid utilization of electrochemical capacitors with other types of energy devices (photovoltaics, fuel cells, and batteries) in a DC microgrid, which ensures wider applications of electrochemical capacitors in the near future. The knowledge and experience in this book are beneficial in manufacturing and utilizing electrochemical capacitors. Cutting-edge knowledge related to novel electrode nano-materials is also helpful to design next-generation electrochemical capacitors. This book delivers useful information to specialists involved in energy storage technologies.
