Abstract

The extensive application of renewable and non-renewable energy storage devices in commercial products and services and the global warming have created significant motivations to accelerate research in battery technology. In addition, the risk factors generated by the high heat generation and flammability of the batteries are being addressed by inventing new renewable or non-renewable energy resources that do not release greenhouse gases into the atmosphere. This thesis discusses the applications of Nuclear Magnetic Resonance (NMR) Spectroscopy in characterizing and understanding novel battery materials as potential battery electrolytes. Works discussed include: the variable temperature characterization of water-based solid polymer electrolyte for lithium-ion batteries (LIB), an investigation of a novel deep eutectic solvent (DES) electrolyte for batteries, the structural and electrochemical characterization of nanofiber added ionic liquid-based gel polymer electrolytes as a self-healing material for LIB applications and investigation of ion diffusion of nanoparticle organic hybrid materials (NOHMs) based polymer electrolyte with doping salts of different concentration and valences.
