Abstract

Current energy technologies for future vehicles primarily focus on the development of energy conversion and storage systems with higher power and energy densities, longer cycle lives, and more competitive costs. However, despite extensive efforts, there have been few significant scientific breakthroughs capable of replacing the far more economical fossil fuel engines. Enhancing durability and continuously exploring alternative materials are essential steps toward accelerating the commercialization of advanced energy systems for electric vehicles by extending their operational lifespans and reducing costs. Energy conversion and storage systems, such as batteries and fuel cells, operate based on electrochemical processes, and their degradation is largely attributed to electrochemically induced phenomena occurring during operation. Therefore, a clear and comprehensive understanding of the underlying electrochemical mechanisms is crucial for improving the stability of these systems. This understanding must inform the development of advanced materials and effective mitigation strategies. In this presentation, I will introduce the work conducted by my research group in the field of materials electrochemistry, with a particular emphasis on enhancing the stability and performance of next-generation battery and fuel cell systems for future electric vehicles and aeromobility applications.
