A state-of-the-art battery system has an energy density in the order of 120 Wh/kg which is low compared to the energy density

An alternative approach having the potential to considerably increase energy densities is making use of several oxidation or reduction steps so that more than one electron can be transferred by an active electrode element. This is possible by solid-state conversion reactions in reactive nanocomposites based on metal nitrides, metal chalkogenides, or metal fluorides.

Debra R. Rolison is head of Advanced Electrochemical Materials at the Naval Research Laboratory (NRL). She received a B.S. in chemistry from Florida Atlantic University in 1975 and a Ph.D. in chemistry from the University of North Carolina at Chapel Hill in 1980 under the direction of Royce W. Murray. Dr. Rolison joined the Naval Research Laboratory as a research chemist in 1980. Her research at NRL focuses on the influence of nanoscale domains on electron- and charge-transfer reactions, with special emphasis on the surface and materials science of aerogels, electrocatalysts, and zeolites. Her program creates new nano structured materials and composites for catalytic chemistries, energy storage and conversion (fuel cells, supercapacitors, batteries, thermoelectric devices), and sensors.
