Our research focuses exclusively on the development of next-generation, lithium ion battery, and beyond-lithium-ion batteries. Such batteries could allow inexpensive electric cars to drive long time on a single charge, rivaling the 400-mile range of conventional gasoline cars. They would also make storing and releasing electricity on the grid just as cheap as generating it with natural gas turbines.

Rechargeable Batteries

Development of new electrode chemistries and novel electrodes for lithium ion batteries, including theoretical and experimental studies of electrode structure and phase transformation and electrode/electrolyte interfaces.

New batteries are required for transport applications and for storage and load-leveling on the electrical grid. These batteries should be capable of being charged and discharged faster, and should store much more power, than the batteries currently available. This requires the development of new electrode chemistries and an understanding of how these systems function. To this end, we study a variety of different rechargeable batteries including lithium, sodium and zinc ion batteries (LIBs, NIBs, and ZIBs).

Electrochemical devices, such as batteries and capacitors, are the best known and perhaps the most promising energy storage systems. Electric double layer capacitors (EDLCs), also known as supercapacitors, have received a significant experimental attention because they can achieve a higher energy density than conventional capacitors and offer a better power performance than batteries. A wide variety of different electrode materials and electrolytes are currently being scrutinized to improve on efficiency and practicality of EDLCs.

We are currently developing and characterizing the performance of new materials for high-density energy storage and economically  viable photovoltaics.
