报告内容:Processing and Microstructure of Cathode Materials for Lithium Ion Secondary Battery
报告摘要:
Rechargeable Li-ion secondary batteries are being developed for use in high power applications, such as fully electric vehicles and hybrid electric vehicles, because of their high energy density and high power density compared to other battery technologies. Future application of multilayer lithium ion secondary batteries requires a thorough understanding of the influence of microstructure on battery performance. In this study, cathode materials such as LiMn2O4 and LiCoPO4 thin film were deposited on various substrates by a chemical solution deposition method, systematically changing the processing parameters to obtain the oriented films. The microstructures of cathode thin films, the interface structures between the films and substrates were characterized using XRD, TEM and STEM to understanding the effects on the properties and the lithium interecalation-deintercalation behavior.
报告人简介:
Dr. Yumi H. Ikuhara received the B.S. degree in pharmaceutical sciences from the Gifu Pharmaceutical University, Gifu, Japan, in 1987, the M.S. degree in materials science and engineering from the Case Western Reserve University, Cleveland, OH, in 1994, and the Ph.D. degree from the Kyoto University, Kyoto, Japan, in 2004.
