Electrochemical Society To Study Inorganic Synthesis for Designing Better Li-Ion Battery Electrodes: On Monday, Sept. 17, the Detroit Section of the Electrochemical Society will hear a program on lithium ion battery electrode chemistry from Bart M. Bartlett of the University of Michigan Department of Chemistry. Maximizing the electrical energy stored in, and drawing high power from Li-ion batteries requires preparative methods that generate high purity nanomaterials. Although low temperature synthesis methods known to generate nanoscale materials have been adapted for promising candidates for Li-ion battery technology, their electrochemical performance is often plagued by point defects, particle aggregation, and impurity phases — all of which can be minimized if one has a thorough understanding of and appreciation for inorganic reaction chemistry. In the talk, Bartlett will highlight three classes of materials currently under investigation in my laboratory: 1) manganese-based spinel nanoparticles synthesized by hydrothermal methods; 2) lithium titanate spinel nanocrystals synthesized by a templated sol-gel method; 3) bronze-phase shrub-like titania synthesized by hydrothermal synthesis followed by aqueous work-up. Bartlett will provide details of the synthetic chemistry used to generate these materials along with guidelines that can be applied to many solid oxides. In addition, Batlett will show that electrodes composed of nanomaterials show similar energy density and stability compared to those composed of their micron-sized congeners. Most important, the rate capability is superior because of the small particle sizes obtained from the synthesis methods. The event will be held in Room 406 of the Taubman Welcome Center at Lawrence Technologial University, 21000 W. 10 Mile Road in Southfield. There will be a reception at 5:30 p.m., dinner at 6:30 and the speaker at 7:30. Use parking lots A, C or D at Lawrence Tech (lots C and D are accessed off Northwestern Highway). The cost is $20 for members, $22 for guests and $10 for students, payable by cash or check. More at www.electrochem.org/ecs/sections/detr/detr.htm.
