Nanocomposite polymer gel electrolyte based on LiBOB–cellulose acetate for lithium–oxygen battery / Siti Zafirah Zainal Abidin

This thesis focuses on the preparation and characterization of liquid electrolytes (LEs), polymer gel electrolytes (PGEs) and nanocomposite polymer gel electrolytes (NCPGEs). In this work, lithium bis(oxalato) borate (LiBOB) salt was incorporated as the source of charge carriers. LEs were first prep...
