This STTR Phase I research proposal will develop novel Nanocomposite Cathode Materials (NCM) that will significantly improve the performance of Lithium-Sulfur (Li/S) batteries in terms of cycle life. The superior properties of the proposed NCMs will be achieved via formation of stabilized sulfur… More

Current state-of-the-art Lithium (Li) or Li-ion systems are unable to meet the performance goals of space-rated rechargeable batteries for many NASA's future robotic and human exploration missions. They either cannot provide sufficient energy and power or have poor cycle or calendar life. TH Chem,… More

Lithium (Li) metal-based rechargeable batteries have many advantages over Li-ion systems including significantly higher energy density, lower cost, and the option of using positive electrode materials that do not have to be pre-lithiated. Unfortunately, Li metal electrodes form metal dendrites upon… More

ABSTRACT: Hydrogen powered fuel cells are promising next generation power source technologies for automobiles and many other portable and mobile electronics. However, application of the technology is greatly hindered by current hydrogen storage technology due to low storage capacity and… More
