Our research goals center on new material and electrode concepts for high power, high energy density, extended life primary and secondary batteries. Our comprehensive research approach is necessitated by the complex nature of battery science and technology, and is facilitated by collaborations with the E. Takeuchi and K. Takeuchi research groups. Specifically, synthesis, characterization, and electrochemistry of solid state metal oxide and phosphate active materials is a focus area (Figure 1)1, with an emphasis on facile ion insertion and deinsertion via control of critical structural and physical materials properties.2 Further, in collaboration with Brookhaven National Laboratory, in-situ and in-operando measurements of some of our battery systems have yielded mechanistic insight into some of the complex chemical and physical processes associated with battery discharge (Figure 2).3 Complementing our the battery materials studies, we have developed new electrode design engineering which reduces passive components and minimizes interfacial resistance.
