국문 초록

As the demand for safety and efficiency in lithium-ion batteries increases, research on solid electrolytes as promising alternatives to conventional liquid electrolytes has gained momentum. This study presents a systematic evaluation of compatibility between oxide-based solid electrolytes and cathode/anode materials, investigating their physical and electrochemical properties. A step-by-step assessment process is proposed, beginning with the structural, morphological, and conductivity evaluations of the solid electrolyte and extending to the interfacial stability and electrochemical performance assessments with cathode and lithium anode materials. For the cathode, compatibility was assessed through high-temperature stability, impedance measurements, and composite formation, with the goal of minimizing side reactions. For the lithium anode, evaluations included surface wettability, interfacial resistance, and lithium dendrite formation. These evaluations provide essential insights into the interactions at the electrode-electrolyte interfaces, enabling optimal material selection and processing methods to enhance battery performance and safety. The results from these compatibility evaluations offer valuable information for researchers and industry practitioners in the development of next-generation solid-state lithium-ion batteries. This research contributes to understanding key parameters for stable interfaces and long-lasting battery performance, advancing high-energy-density and safe lithium battery technologies.
