Understanding And Controlling Failure Mechanisms Of The Zinc Anode For Rechargeable Alkaline Batteries, Michael J. D'Ambrose
Understanding And Controlling Failure Mechanisms Of The Zinc Anode For Rechargeable Alkaline Batteries, Michael J. D'Ambrose
Dissertations and Theses
In the coming years, the transformation of the electric grid will be in part enabled by safe, low-cost, and reliable large-scale rechargeable battery energy storage systems. Zinc (Zn) alkaline electrodes hold great importance and promise in the battery technology community as they satisfy the safety and cost requirements, yet their behavior in real world application is still poorly understood.
Two experimental studies were carried out, the first of which investigates failure mechanisms and material evolution during cycling of 27 zinc-manganese dioxide (Zn-MnO2) cells in 37 wt% potassium hydroxide (KOH) electrolyte wherein the percent utilization of the theoretical capacity …
Design, Product Development And Risk Assessment Of Tin (Sn) Ring Electrodes As A Substitute To Silver-Silver Chloride (Ag Agci) Ring Electrodes For High Definition Transcranial Direct Current Stimulation (Hd-Tdcs), Linford Leitch
Dissertations and Theses
The objective of this research thesis is to test the viability of Tin (Sn) ring electrodes as an inexpensive alternative to sintered Silver-Silver Chloride (Ag|AgCl) ring electrodes for High Definition – transcranial Direct Current Stimulation (HD-tDCS). Throughout our initial bench top testing of tin electrodes in combination with a ‘conductive electrode gel’, the passing of a 2mA direct current on agar block showed the formation of white cloud around the anode electrode and a cluster of air bubbles on the cathode. The analysis of pertinent literature indicates that the white milky substance produced during the stimulation at the anode is …
