We work to elucidate basic structure-property correlation at atomic and nanometric scales for charge-storage materials. Such correlation guides us to design and synthesize advanced electrode materials to enable sustainable energy storage and conversion solutions. We integrate electrochemical principles with basic material chemistry to explore new charge storage mechanisms and device configurations.
