| Abstract Scope |
Li-batteries are promising candidates for sustainable energy storage, although their use in high energy density applications is still a challenge. Key limitations of battery performance include the structural instability of battery materials with continuous usage, and high energy density requirements. The central aim of our research is to crystallographically engineer electrode microstructures, in order to enhance battery lifespan and energy storage capacity. We use martensite crystallographic theory and phase field methods to design a new generation of battery materials, which offer minimum volume changes and enhanced conductivity. In this talk, I will discuss crystallographic engineering of battery materials in two studies: First, I will present how repeated charging/discharging of battery affects electrode crystallographic texture making them brittle. Second, I will show how grain boundaries and edge-dislocations alter electrode's strength and Li-diffusion properties. Overall, our study provides a theoretical framework to crystallographically engineer battery materials with enhanced performance. |
