演 題：Electrical Characteristics of Sn-based Anode Materials and LTO for Lithium Ion Battery
講演内容： Tin is a promising material for the anode of lithium ion battery, but it has problems of volume expansion during the charge and discharge process. In order to reduce the volume expansion problems mixture oxides were prepared.
To make an SnO, sol-gel process was tried. The mechanical and electrochemical properties were tested.
Lithium titanium oxide is a candidate for the anode material because the cyclability is very stable. In order to increase the conductivity of the material, addition of metal was tried.
Sol-gel process was also tried for this material. The mechanical and electrochemical properties were also tested.
TGA, XRD, SEM, XPS was used to analyze crystal structures and surface properties. The material was pasted on the copper sheet and assembled to the coin cell. The charge/discharge properties and the cycle characteristics were analyzed by battery cycler.
