dc.description.abstract | In this research, Li4Ti5O12 anode with doping Al2O3 and carbon coating was
made to determine the effect of doping Al2O3 and carbon coating on crystal
structure, morphology and electrochemical performance. Li4Ti5O12 anode material
consist of LiOH.H2O and TiO2 was made with various samples of LTO without
doping, LTO doped carbon, LTO doping Al2O3 and carbon using the solid state
reaction method. All raw materials are mixed and milled using a Planetary Ball
Miller for 2 hours so then crushed to become a precursor to Li4Ti5O12. The Li4Ti5O12
precursor was sintered at 850 ° C for 4 hours. The final product was characterized
using X-Ray Difraction (XRD) to determine the formation of Li4Ti5O12 phases,
Scanning Electron Microscopy (SEM) to analyze the morphology formed, and Cyclic
Voltammetry to determine electrochemical performance. The results of XRD
characterization were formed in the Lithium Titanium Oxide (Li4Ti5O12), Dilithium
Titanate (Li2TiO3), and Rutile (TiO2) phases. The SEM characterization results on
LTO doping carbon, LTO doping Al2O3 and carbon showed a coarser texture
compared to the LTO without doping which had a fine texture. The electrochemical
performance produced in LTO coating carbon has a slender redox peak in the first
cycle, this shows that LTO coating carbon has good electrochemical performance
compared to the Al2O3 and carbon doping LTO samples. | en_US |

Material anoda Li4Ti5O12 terdiri dari LiOH.H2O dan TiO2 dibuat dengan variasi
sampel LTO tanpa doping, LTO doping carbon, LTO doping Al2O3 dan carbon
menggunakan metode solid state reaction. Semua bahan baku dicampur dan digiling
dengan menggunakan alat Planetary Ball Miller selama 2 jam jadi kemudian digerus
untuk menjadi prekursor Li4Ti5O12. Prekursor Li4Ti5O12 disintering dengan suhu
850oC selama 4 jam. Produk akhir dikarakterisasi menggunakan alat X-Ray
Difraction (XRD) untuk mengetahui pembentukan fasa Li4Ti5O12, Scanning
Electron Microscopy (SEM) untuk menganalisa morfologi yang terbentuk, dan
Cyclic Voltammetry untuk mengetahui performa elektrokimia. Hasil karakterisasi
XRD terbentuk pada fasa Lithium Titanium Oxide (Li4Ti5O12), Dilithium Titanate
(Li2TiO3), dan Rutile (TiO2). Hasil karakterisasi SEM pada LTO doping carbon,
LTO doping Al2O3 dan carbon menunjukkan tekstur yang kasar dibandingkan pada
LTO tanpa doping yang memiliki tekstur halus. Performa elektrokimia yang
dihasilkan pada LTO coating carbon memiliki puncak redoks yang ramping pada
siklus pertama, hal ini menunjukkan bahwa LTO coating carbon memiliki performa
elektrokimia yang bagus dibandingkan pada sampel LTO doping Al2O3 dan carbon. | en_US |
