Advanced non-precious metal catalyst for oxygen reduction reaction in polymer electrolyte membrane fuel cells
(University of Waterloo, 2017-09-20)To address the global energy and environmental challenges, the polymer electrolyte membrane fuel cell (PEMFC) is proposed and developed as one of the most promising power source candidates for various applications including ... -
Cyclic Biamperometry
(University of Waterloo, 2009-08-17)In this thesis, cyclic biamperometry (CB) as a new method in electrochemistry, has been introduced and investigated. The hallmark of this method is the absence of a reference electrode which potentially allows simplification ... -
Development of Co-Assembly Methods for Improved Graphene/Ionic Liquid Supercapacitors
(University of Waterloo, 2017-08-31)Supercapacitors, also known as electric double-layer capacitors or ultracapacitors, store energy by rapid and reversible rearrangement of ions/charges at the electrolyte/electrode interface. This physical process results ... -
Experimental and Modeling Study of Nickel, Cobalt and Nickel-Cobalt Alloy Electrodeposition in Borate-Buffered Sulphate Solutions
(University of Waterloo, 2011-04-29)Nowadays, the development of novel materials involves diverse branches of science as a consequence of the new requirements imposed by modern society. This includes aspects ranging from the optimization of the manufacturing ... -
Novel High Voltage Electrodes for Li-ion Batteries
(University of Waterloo, 2013-08-30)An alternate family of “high” voltage (where the equilibrium voltage lies between 3.6 V and 4.2 V) polyanion cathode materials is reported in this thesis with the objective of improving specific energy density (Wh/kg) and ... -
Silicon-based Materials as Negative Electrodes for Li-ion Batteries
(University of Waterloo, 2014-05-02)Silicon is a promising negative electrode material for lithium-ion (Li-ion) batteries, with volumetric and gravimetric capacities much higher than those in current commercial batteries. Implementation of Si as a negative ... -
Synthesis, Electrochemistry and Solid-Solution Behaviour of Energy Storage Materials Based on Natural Minerals
(University of Waterloo, 2013-04-15)Polyanionic compounds have been heavily investigated as possible electrode materials in lithium- and sodium-ion batteries. Chief among these is lithium iron phosphate (LiFePO4) which adopts the olivine structure and has ...
