ICAMST 2018 Synthesis and Characterization of Al-Doped Li 4 Ti 5 O 12 with Sol Gel Method for Anode Material Lithium Ion Battery Ilma Nuroniah a , Slamet Priyono a, *, Achmad Subhan a , Bambang Prihandoko a , Andi Suhandi a , Ahmad Sohib a a Research Center for Physics - Indonesian Institute of Science, Kawasan PUSPITEK Gedung 442 Serpong, South of Tangerang 15314, Indonesia Abstract Spinel Li 4 Ti (5-x) O 12 Al x (x = 0, 0.05) was synthesized via sol gel method. The samples were sintered at 800 o C for 4 hours. The characterization of material and electrochemical performance was analyzed by X-ray diffraction, charge discharge test, cyclic voltammetry and EIS. The results show that the addition of doping Al 3+ ion does not changed the structure of Li 4 Ti 5 O 12 . The anodic and cathodic current peaks from cyclic voltammogram are higher and sharper as scan rate increases. The electrical conductivity Al-doped Li 4 Ti 5 O 12 has higher than Li 4 Ti 5 O 12 pristine. Charge discharge curve indicated that Li 4 Ti 5 O 12 pristine has good rate capability battery. © 2019 Elsevier Ltd. All rights reserved.

Introduction Li 4 Ti 5 O 12 is promising material to replace graphite as anode material for Lithium Ion Battery. It has a long life cycle, high power density with the high relatively theoretical capacity (175 mAh/g), stable structure during insertion or de-insertion lithium ion processes and thermodynamically flat discharge at 1.55 V Li/Li + , so the electrolyte * Corresponding author.
