New Perspectives of Energy Storage Materials

submitted by: RASEIBoulder
Summary: Energy storage in the electrochemical form is attractive because of its high efficiency and fast response time. New and improved materials for energy storage are urgently required to make more efficient use of our finite supply of fossil fuels, and to enable the effective use of renewable energy sources. In this seminar, I will discuss a few new perspectives for energy storage materials including new Li intercalation compounds, new Na intercalation compounds and new...

Batteries for Hybridization and Electrification of Vehicles

submitted by: RASEIBoulder
Summary: More than 30% of US energy and 90% of oil consumption are used for roadway transportation. Hybridization and electrification of vehicles on roadways are considered as major strategies for reducing dependence on oil and greenhouse gas and meeting the aggressive fuel economy standards. Hybridization of conventional internal combustion engine vehicles with motors run on electricity from batteries can significantly improve fuel efficiency while electrocution allows switch of the fuel to...

Investigating Structure Variation of Electrode Materials for Lithium Ion Batteries

submitted by: RASEIBoulder
Summary: Improving energy density, power density, cycle life and safety and decreasing cost of current Li-ion batteries are highly desirable for the applications of advanced portable electronic devices, electrical tools, electrical vehicles, storage batteries for renewable energy, and stationary batteries for smart grids. Understanding lithium storage mechanism and structure-property relationship across length scales are essential for rational design of new materials. Here we report our...
