Abstract: The all-solid-state battery is hailed as the next generation of energy storage. It has the potential to drastically improve the safety, energy density, and cost of the battery. Therefore, there have been many avenues developed to achieve a solid-state electrolyte (SSE). This project focuses on the two least investigated approaches of SSE advancement. The first approach utilizes a plastic crystal to improve the ionic conductivity of a solid polymer electrolyte (SPE), while the latter explores the possibility of employing a lithium-based metal-organic framework (MOF) as a solid-state electrolyte. Although there is much research performed on various plastic crystal electrolytes, their ion conduction mechanism remains a controversial topic. Similarly, MOFs are a novel class of materials, and their functionality within the lithium-ion battery needs to be further examined. This work studies the synthesis, thermal, electrochemical, and optical properties of the plastic crystal and MOF electrolytes, with an emphasis on their ion conduction mechanism.
