Opportunity Description

Research on High-Energy Density and High Power Density Electrochemical Energy Storage Devices High-power density lithium-ion (Li-ion) batteries and electrochemical capacitors with high energy density are increasingly needed in applications such as power tools, robotics, unmanned aerial vehicles (UAV), and hybrid electric vehicles (HEV). The state-of-the-art Li-ion batteries have encountered substantial reduction in power performance at temperatures below -30oC and reduced cycle and storage life at temperatures above 60oC. Furthermore, under shorting and overcharge conditions, the current Li-ion batteries will undergo thermal runaway and become dangerous. The energy density of the current Li-ion chemistries has reached their limits, 200 to 250 Wh/kg, while higher energy density Li-ion batteries are still desirable. Research and development activities include investigation of factors limiting the low-temperature charge-transfer kinetics at the electrode/electrolyte interfaces, understanding solid-electrolyte interface (SEI) formation resulting from the electrolyte and electrode reactions for guiding materials development, synthesis and characterization of new solvents and salts for improved electrolytes and SEI properties, development of high voltage cathode for increased energy density, and development of compatible high voltage electrolytes.

About Us

Oak Ridge Associated Universities (ORAU) administers Science, Technology, Engineering and Mathematics (STEM) research participation programs for civilians such as:

The U.S. Army Research Laboratory (ARL) Research Associateship Program (RAP) allow Postdoctoral Fellows, Journeyman Fellows (undergraduate and graduates students and recent graduates), Senior Researchers, and Summer Faculty engage in research initiatives of their own choice, that are compatible with the interests of the government and will potentially contribute to the general effort of the ARL. Scientists and engineers at ARL help shape and execute the Army's program for meeting the challenge of developing technologies that will support Army forces in meeting future operational needs.

Research opportunities include, but are not limited to the following disciplines: Aerospace Engineering, Anthropology, Archeology, Biology, Biochemistry, Biological Engineering, Biomechanical Engineering, Biomedical Engineering, Chemical Engineering, Chemistry, Computer Science, Computer Engineering, Electrical Engineering, Environmental Health Risk Assessment, Environmental Science, Entomology, Epidemiology, Ergonomics, Geology, Health Education Mechanical Engineering, Materials Science, Mathematics, Nanotechnology, Photonics, Physics, Public Health Economics, Public Health Policy, and more.
