- 요약As the world transitions away from using fossil fuels as the primary source of energy, we must develop better energy storage technologies including batteries to enable global utilization of renewable energy. Lithium-ion batteries (LIBs) have been the dominant type of battery for several decades, and considerable research is ongoing to develop new battery technologies with higher energy density and lower cost. One leading new technology is the solid-state battery (SSB), where the liquid electrolyte and polymer separator of the LIB are replaced by a solid-state electrolyte (SSE) that can conduct Li+ ions. SSBs offer potentially higher volumetric and gravimetric energy density, greater safety, and equivalent or superior lifespan compared to LIBs. However, substantially more research is required before SSBs can be commercialized on a broad scale and successfully rival LIBs in the market. Although the operative principals of LIBs and SSBs are similar, SSBs pose a variety of unique issues owing to the absence of liquid electrolyte. First, the ionic conductivities of most SSEs are lower than liquid electrolytes, which limits fast charging capabilities. Second, solid-solid contact at interfaces within the battery is inherently worse than liquid-solid contact, making it difficult to fully utilize the active material stored in the battery; furthermore, the resistances associated with the solid-solid interfaces lower the efficiency and power output of the battery. Third, the manufacturing of uniform solid-state electrolytes is an important objective since it is critical to have highly uniform, high-performing SSEs within the battery. These are three of the major topics surrounding solid-state batteries that researchers in academia and industry are working to understand. Solving these practical issues is critical to making SSB technology truly commercially viable. In this thesis, I cover these three topics -- the structure-ionic conductivity relationship, SSB interfaces, and scalable manufacturing of uniform SSB materials -- across three SSE classes -- sulfides, oxides, and polymers. First, I discuss two different lithium thioborate solid electrolytes, and although the building blocks of these electrolytes are similar, the structures and factors affecting their ionic conductivity are different. The relationship of structure with ionic conductivity is thoroughly investigated, and the electrolytes are cycled in practical, high-capacity batteries. Second, I discuss the scalable manufacturing of thin-film solid-state batteries using amorphous Li7La3Zr2O12 as the SSE and crystalline LiCoO2 as the cathode. Third, I discuss polymer-inorganic composite electrolytes using inexpensive additives (Li3N and LiOH) and the impact of the additive choice on the SSE-anode interface and cyclability. The scope of my research is important because for SSBs to reach their potential, we must be able to synthesize SSEs with sufficiently high ionic conductivity and interfacial stability, and this is only possible by studying and truly understanding SSE's structure and ion conduction mechanisms. Research such as what I present in this thesis will be critical to finding the optimal SSE and battery configuration that can enable the commercialization of SSBs.
