Approaches to Evaluating and Improving Lithium-Ion Battery Safety

submitted by: RASEIBoulder
As lithium-ion battery technologies mature, the size and energy of these systems continues to increase for emerging applications in transportation, grid storage, military use and aerospace. In fact, broadening the application space for lithium-ion batteries from the consumer electronics industries to these emerging markets increases their size from 1-50 Wh batteries for smart phones and laptops to >50 kWh for electric vehicles (EVs) and MWh scale for utility storage systems. As these...

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...

GREEN REVOLUTION: ELECTRIC VEHICLES

submitted by: nsf
Host Lisa Van Pay visits the scientists and engineers working to make the electric car of the future a reality today. One of the toughest parts is storing enough potential energy to get you where you’re going, and in this case, it’s all about the battery. Graduate student Katharine Stroukoff from the University of Texas-Austin explains how her research may help build a better battery, while Mike Nawrot and Dan Lauber, members of the MIT electric vehicle team, describe the advantages of...
