Harovel G. Wheat MANGANESE OXIDE CATHODES FOR RECHARGEABLE BATTERIES

Dedicated To my wife, Dohee Kwon v Acknowledgement First of all, I would like to express my deep gratitude to my advisor, Dr. Arumugam Manthiram, for having guided me to finish my research successfully and provided me precious support and constant encouragement. Without his support, it would have taken much longer to finish my work.

Li2MnSiO4 Nanostructured Cathodes for Rechargeable Lithium-Ion Batteries

Rechargeable lithium-ion battery technology dominates the portable electronics market following the rapid growth in demand since the introduction of the first, commercial lithium-ion battery by Sony in 1990 [1]. Motivated by concerns for global warming and environmental degradation, researchers have focused on extending the use of rechargeable lithium-ion batteries to large-scale applications. ...

A new ether-based electrolyte for dendrite-free lithium-metal based rechargeable batteries

A new ether-based electrolyte to match lithium metal electrode is prepared by introducing 1, 4-dioxane as co-solvent into lithium bis(fluorosulfonyl)imide/1,2-dimethoxyethane solution. Under the synergetic effect of solvents and salt, this simple liquid electrolyte presents stable Li cycling with dendrite-free Li deposition even at relatively high current rate, high coulombic efficiency of ca. ...

Rechargeable Batteries

Purpose: The goal of our battery research is to produce an all solid-state, high performance rechargeable cell. Moving to a liquid-free polymer electrolyte eliminates the need for heavy casing material, thus the energy density is increased significantly. In addition, the absence of solvent additives leads to better thermal and chemical stability, broadening the range of applications for which t...
