Lithium-ion batteries (LIBs) are a core component in electric vehicles (EVs). They provide energy to run EVs by converting the stored chemical energy into electrical energy. The quality of the battery system determines the cost of EVs' and single charge driving range. Hence, it is required to develop advanced LIBs and/or alternative battery systems with higher energy and power densities. Recently, solid-state lithium-ion batteries (SS-LIBs) are in-focus as they provide additional benefits in-terms of safety and feasibility for high energy-density EVs. Since, the LIB technology is solely concentrated on electrochemistry, the degradation mechanisms can be figured out by understanding the interface between electrode/electrolyte (both liquid- and solid-electrolyte), which helps in improving cell design for advanced batteries. However, understanding the interfacial degradation mechanisms of LIBs and SS-LIBs still remains the biggest challenge owing to its difficulty to treat micro-scale. This dissertation focuses on understanding battery degradation mechanisms, improving cell designs by surface modification, suggesting novel electrode materials, and showing the optimized interface between electrode/electrolyte for solid-state LIBs. In order to investigate the interfacial studies, a variety of materials characterization techniques were conducted, and diverse electrochemical evaluations were performed. This study will widen the insight into advanced lithium-ion batteries.
