THE EFFECT OF NANO SN ADDITION TO Li4Ti5O12 NANOROD ANODE PERFORMANCE IN LITHIUM ION BATTERY APPLICATION

Research has been conducted to study the synthesis of nanorod Li4Ti5O12 (LTO) and the effect of Sn nanopowder and activated carbon addition to the battery performances. Firstly, Sol-gel process was conducted to synthesize TiO2 powder which further subjected to hydrothermal process to obtain nanorod structure. Moreover, The Li4Ti5O12 was prepared through solid-state method. Activated carbon were prepared using NaOH 1M as activation agents while Sn nanopowder was added by 10 wt%, 15 wt%, and 20wt%. The powder then characterized by SEM-EDX, XRD, and BET, and the cell performance was tested using CV, CD, and EIS. The impurities such as Rutile TiO2, and Li2TiO3 present. The highest capacity was achieved by 20 wt% Sn addition which value is 192.1 mAh/g.
