Abstract Scope |
Solid-state batteries (SSBs) are promising alternatives to conventional metal-ion batteries due to their potential to address safety concerns related to liquid electrolytes. This study focuses on improving SSBs' electrochemical performance by optimizing the multi-component solid electrolyte blends. Computational models were utilized to systematically obtain the optimized blend ratio by exploring binary and ternary blends. This systematic evaluation enhances Li-ion mobility and overall electrochemical performance, leading to improved battery characteristics. A novel diffuse-interface approach has been employed to analyze the impact of phase-separating blends on SSBs upon considering factors like electrode-electrolyte interfacial area and energy level differences among phases. The optimized blend ratio resulted in a significant improvement of 38.15% and 8.11% in the overall potential difference across the SSB for binary and ternary solid electrolyte blends, respectively. This research advances SSB technology by optimizing the solid electrolyte morphology, and facilitating the development of safer and more efficient energy storage systems. |
