Linking redox chemistry, ion transport, and structural evolution to design cathodes with high capacity and durable cycling. Our group studies Li-rich layered oxides, high-Ni layered cathodes, and disordered-rocksalt materials. We resolve how high-valent transition-metal and oxygen redox, cation migration, oxygen dimerization, and phase evolution control capacity, voltage hysteresis or decay, and long-term stability. By integrating atomistic computation, synthesis, electrochemistry, and multiscale characterization, we translate degradation mechanisms into practical design rules. We integrate first-principles computation, high-throughput screening, synthesis, and multiscale characterization to discover advanced energy materials. Reveal the origins of electrochemical behavior and degradation. Design and validate materials for next-generation batteries. Using first-principles calculations, high-throughput screening, and machine learning to explore chemical space systematically. Establishing chemistry-specific design rules for affordable sodium-ion electrodes with high energy and long cycle life. An emerging direction connecting superionic-conductor design with stable solid-solid interfaces.
