Battery Materials Research

The fundamental theoretical limit in the energy density of intercalation-based Li-ion chemistry can be overcome by exploring non Li-ion batteries. This also serves to alleviate anxiety about the depletion of lithium by fast-growing trends in renewables, consumer electronics and electrification of transportation. We are interested to study and address the fundamental material problems in such next-generation battery chemistries. Our research is focused on Na-, Mg- and Al-ion batteries in a move away from the use of Li. Exploring fundamental concepts from materials chemistry and physics, we design novel battery materials (cathode, anode, electrolyte), understand structure-property relationships, and construct battery prototypes for portable electronics, electric vehicles, grid energy storage, etc.
