Overview
The development of high-performance solid-state batteries requires a fundamental understanding of how the composition, structure, and interfaces of electrode and electrolyte materials determine electrochemical behavior. Research is focused on the design and synthesis of new battery materials and on clarifying their reaction and degradation mechanisms through electrochemical, structural, and spectroscopic characterization. The aim is to establish materials design principles for high-performance and sustainable energy-storage systems.
Novelty and originality
• Design, synthesis and testing of new electrode and electrolyte materials for solid-state batteries
• Fundamental understanding and control of structure–property relationships governing electrochemical performance and stability
• Integration of materials synthesis, advanced characterization, and electrochemistry for high-performance and sustainable energy-storage systems
Details
The relationships between structure, electrochemical reaction, and battery performance are investigated to guide the development of electrode materials for solid-state batteries. In Li-rich cathode materials, in-situ X-ray diffraction is used to track structural changes during charge and discharge and to clarify their relationship with phenomena such as voltage hysteresis. Microstructural effects are also examined to understand particle fracture and improve cycling stability through control of grain size and grain boundaries. In parallel, new cathode materials are designed, synthesized, and evaluated in solid-state batteries, combining electrochemical testing with structural and spectroscopic characterization to clarify their redox mechanisms and identify factors governing capacity and long-term stability.
Summary
• Elucidation of structural, microstructural, and redox factors governing the electrochemical performance and stability of battery materials
• Development of new electrode and electrolyte materials through the integration of materials synthesis, electrochemical evaluation, and advanced characterization
• Application of these insights to the design of high-performance and sustainable materials for next-generation solid-state batteries
