This book was released on 1967 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zinc electrodes have been subjected to constant anodic potential polarization for different time periods in various KOH solutions. The voltage level was varied and the work was carried out at 25 and -3C. The voltage decay was followed immediately after polarizing current was removed. Above 325 mv a voltage arrest was observed in this voltage decay curve. This arrest may be due to a mixed potential tegether with a passivating film on the zinc electrode. (Author).

Download or read book Investigation of the Transport and Reaction Processes Occurring Within Silver Oxide zinc Batteries written by Thedford Preston Dirkse and published by . This book was released on 1966 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The decomposition of Ag2O dissolved in KOH solutions was studied; effects of temperature, light, KOH concentration, Ag2O concentration, and additives on this decomposition were measured. At least two mechanisms are involved but the precise nature of these mechanisms is still unknown. Overvoltages for anodic and cathodic zinc electrode processes were measured by different methods. The presence of additives in the electrolyte had little effect on these overvoltages but overvoltages were markedly affected by KOH concentration and temperature. Amalgamation improved performance of the Zn electrode but this effect decreased with decreasing temperature. Ag contamination adversely affected cathodic Zn electrode processes. It appears that the beneficial effects of additives to the electrolyte are related to the presence of carboxyl groups and that the beneficial effects of additives to the Zn electrode are related to their wetting ability.

Download or read book Silver Migration and Transport Mechanism Studies in Silver Oxide zinc Batteries written by T. P. Dirkse and published by . This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thirteen different materials were checked for their reaction towards silver oxide dissolved in potassium hydroxide solutions. Of these, the polyethylenes appear to have most promise as separator materials. Several attempts were made to trace the migration of silver in a silvercadmium cell by the use of radioactive silver. A method of counting the radioactivity is being developed. The main difficulty encountered in this study is the take-up of radioactive silver by the electrodes. This has obscured the interpretation of the results obtained to date. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The processes that control the useful life time and performance rates in non-flowing zinc electrodes for electrical storage batteries have been investigated. In particular, the chemical reaction rates, concentration, and electrical potential distributions have been predicted theoretically and measured experimentally as functions of position in the electrode and time for both charge, discharge, and multiple cycles. Changes in crystal structure and solid distributions have also been measured and examined theoretically. Similar rates and distributions have been measured and correlated for RAI P2291 ion exchange membrane separators used in zinc secondary batteries such as the nickle-zinc battery (An/KOH, H2O/NiOOH). Distributions in flow through electrodes were also observed experimentally and calculated theoretically, using the copper deposition reaction for experimental convenience. Work was begun on the theoretical description of the nickle oxide electrode. Experimental work is being planned to validate and revise our understanding of how the nickel electrode operates. Work is continuing on measurement of concentration profiles in zinc electrodes. (Author).

Download or read book The Zinc Bromine Flow Battery written by Gobinath Pillai Rajarathnam and published by Springer. This book was released on 2016-01-11 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a detailed technical overview of short- and long-term materials and design challenges to zinc/bromine flow battery advancement, the need for energy storage in the electrical grid and how these may be met with the Zn/Br system. Practical interdisciplinary pathways forward are identified via cross-comparison and comprehensive review of significant findings from more than 300 published works, with clear in-depth explanations spanning initial RFB development to state-of-the-art research in related systems. Promising strategies described include the use of modern electrochemical techniques to study and optimize physical processes occurring within the system during operation, improving zinc electroplating quality during the charge phase through the strategic use of organic additives, as well as identifying suitable catalysts to optimize the bromine/bromide redox couple. The primary focus is on research and development of novel materials in the areas of electrolyte formulation and multifunctional “smart” electrode surfaces to achieve a higher degree of control over processes at the electrode–electrolyte interface. The strategies suggested in this book are also highly adaptable for use in other similar flow battery systems, while the unique cross-comparative approach makes it a useful reference and source of new ideas for both new and established researchers in the field of energy storage and battery technology.
