Özet:
In recent decades, ionic liquids (ILs) have received substantial interest for their application as viable electrolytes in energy storage devices due to their low flammability, adequate ionic conductivity, and wide electrochemical window. Room-temperature ionic liquids possess a melting point below room temperature and consist entirely of cations and anions. Here, traditional imidazolium/pyrrolidinium ILs and solvate lithium-based ILs are presented for their application in supercapacitors and lithium-ion batteries. Additionally, considerable demand exists for the fabrication of a flexible, robust, highly conductive solid-state electrolyte for applications in light-weight, flexible electronics. This thesis demonstrates the design of polymer-supported ionic liquid gel electrolytes, defined as ionogels, via in situ UV-initiated free-radical polymerization.
Solid-state electrolytes experience a hindrance in electrochemical properties due to the presence of a highly viscous polymeric network. This investigation seeks to define the chemical and physical interactions between a polymer-based scaffold and ionic liquid-based electrolytes in order to leverage these properties to enhance the electrochemical and mechanical properties of the solid-state composite. This proposal seeks to achieve this by the following methods: (1) chemically-tailored polymer scaffolds and (2) zwitterionic-based networks that possess an equal number of positive and negative moieties. Enhancement of properties such as the ionic conductivity, fraction of available free ions, lithium-ion mobility, lithium-ion transference number, and Li battery performance are the focus of this investigation in order to prepare commercially viable gel electrolytes for energy storage applications.
