Abstract
Li4SnxTi5�xO12 was manufactured by high energy ball milling (HEBM) and used as an anode material for lithium ion battery. Various amount of SnO2 was added to Li4Ti5O12 and heated at different temperatures. The purpose of this research was to see the effect of SnO2 addition into Li4Ti5O12. Manufactured samples were analyzed by TGA, XRD, SEM, PSA. Battery cycler was used to test the charge/discharge properties of active materials. Heat treatment tem- perature of 800 o C was needed to make a stable structure of Li4SnxTi5�xO12 and the particle size distribution was 0.2~0.6 µm. Charge/discharge process was repeated for 50 cycles at room temperature. The initial capacity was 168 mAh/g and the voltage plateau was observed at 1.55 V(Li/Li + ).
