Battery Lecture-Daniel Abraham of Argonne National Laboratory speaking April 22
March 30, 2010
Daniel Abraham, Materials Scientist and Team Leader, Advanced Battery Research for Transportation (ABRT) program, Argonne National Laboratory, will give lecture titled “Lithium-ion batteries: current chemistries, future opportunities” on Thursday, April 22, 2010 from 4:30 p.m. to 5:30 p.m. in Wetherill Hall (WTHR), room 104.
Lithium-ion Batteries: Current Chemistries, Future Opportunities The lithium-ion cell has become the front-runner in rechargeable battery technologies having found applications in industries as diverse as portable electronics, medical devices, and outer space technologies. Lithium-ion batteries are also expected to replace the nickel metal hydride battery packs used in currently available hybrid electric vehicles because of their higher energy storage and power densities. However, the mass commercialization of these batteries for transportation applications has been hampered by high cell costs, safety concerns, limited cell life, and poor performance at temperatures below 0°C. Research to overcome these limitations is being conducted on high-power and high-energy lithium ion cells at Argonne National Laboratory, as part of DOE’s Advanced Battery Research program. Various battery chemistries, including negative electrodes with various graphite morphologies, positive electrodes containing layered- and spinel- oxides, and electrolytes containing various salts and additives have been examined to identify material combinations that can meet the 15-year calendar life goal established by DOE’s FreedomCar initiative. This presentation will review some of the lithium-ion cell chemistries being considered for commercialization, highlight ongoing research strategies, and discuss challenges that remain regarding the synthesis, characterization, electrochemical performance, and safety of these systems.

Groups of high schoolers eagerly lined up Tuesday morning at Purdue University to test how well their handcrafted wind turbines would perform when stacked against the power of four fans. The kids were competing to create a turbine that would generate the most energy as a part of a challenge for the Duke Energy Academy at Purdue. The annual academy, now in its fifth year, brings in U.S. high school students to learn about renewable energy with hopes they'll be inspired to pursue careers in science, technology, engineering and mathematics fields and solve energy challenges. "We want these students to be the leaders of tomorrow," said Pankaj Sharma, managing director of the Purdue Energy Center and Global Sustainability Institute. The academy lasts throughout the week and is hosting 52 students and 27 teachers from mainly Indiana schools, though about 20 percent come from outside states, said Tolu Omotoso, a civil engineering graduate student and coordinator for the academy.Read Full Story
