Development of a Lab-Scale, Rechargeable, Aqueous Coin Cell and Methods for Measuring the Self-Discharge Rate of Zinc Electrodes
(2015)Zinc-air cells are promising as a cheap, safe and sustainable energy storage technology, but few publicly funded institutions currently research them. One reason for this is a lack of a simple, standardized cell design to ... -
Evaluating Degradation Mechanisms in Next-generation Electrode Chemistries
(2021-12-17)Electrode degradation is one of the major obstacles hindering the implementation of new electrode chemistries into practical batteries. In this thesis, studies regarding the electrode degradation of some next-generation ... -
Layered Oxide Phases for Sodium-ion Battery Electrodes
(2014-08-25)Sodium-ion batteries could offer an economical and environmentally friendly alternative to lithium-ion batteries, however many challenges must be overcome first. This project focused on the investigation of layered sodium ... -
Lithium-Rich Transition Metal Oxides as Positive Electrode Materials in Lithium-Ion Batteries
(2010-11-19)Lithium-rich transition metal oxides are candidates for the next-generation lithium-ion battery positive electrode materials. They have a much higher first charge and low-rate cycling capacity compared to non-lithium rich ... -
METAL OXIDE NEGATIVE ELECTRODES FOR SODIUM-ION BATTERIES
(2015)Sodium-ion battery technology is of interest for energy storage applications because it has the potential to be sustainable and cost effective. Currently, the lack of a suitable negative electrode material limits the ... -
Scientific Institution Notes
(2009-07-28)This notebook kept by James Dinwiddie between June 5 and June 29, 1809 contains notes on lectures that focus on a range of topics in chemistry including voltaic electricity, decomposition of salt and potash, and electrochemistry. ... -
Studies of Oxygen Reduction Electrocatalysts Enhanced by Dealloying
(2011-09-07)Dealloying refers to the partial, selective dissolution of the less noble component(s) of a binary or ternary alloy precursor, resulting in a noble-rich, porous structure that has high surface area. Such surface structure ... -
Synthesis and Characterization of Magnesium and Manganese Doped LiCoO2
(2017-07-17)LiCo1-2xMgxMnxO2 (0 ≤ x ≤ 0.05) positive electrode materials were prepared from Co1-2xMgxMnx(OH)2 (0 ≤ x ≤ 0.05) co-precipitated precursor materials by mixing precursor materials with Li2CO3 and heating. All precursor and ... -
UNDERSTANDING AND PREVENTING LIFETIME FAILURE IN LITHIUM-ION BATTERIES
(2021-08-24)Researchers are rushing to improve the lifetime, energy density, and cost of lithium-ion batteries as their production grows to match increasing demand. They can achieve these goals by finding new electrolyte additives ...
