Abstract
Fe2O3 merupakan salah satu kandidat terbaik yang dapat digunakan menjadi
anoda baterai lithium ion karena Kapasitas yang besar mencapai 1005mAh/g,
ketersediaan luas, ramah lingkungan, murah dan proses pengolahan mudah.
Dalam Penelitian ini telah berhasil disintesa Fe2O3 menggunakan metode
hidrothermal dengan melakukan penambahan glycine sebesar 3, 6, dan 9 mmol
pada temperatur hidrothermal 140, 160 dan 180 OC selama 10 jam. Morfologi
yang diperoleh berupa Fe2O3 nanoellipses dengan ukuran antara 90-200 nm.
Hasil yang diperoleh didapatkan kapasitas discharge awal tertinggi sebesar 634
mAh/g pada range antara 0.01 sampai 3 V untuk spesimen dengan penambahan
glycine sebesar 9 mmol pada temperatur hidrothermal 160 OC. Hal ini
menunjukan jika Fe2O3 berpotensial untuk digunakan sebagai anoda baterai
Lithium ion..

Abstract: Fe2O3 is one of the best candidates that can be applied as an anode for
lithium ion batteries because of a large theoretical capacity 1005 mAh/g, wide
availability, low production cost and environmentally friendly. In this study has
been successfully synthesized Fe2O3 using hydrothermal method by adding
glycine at 3, 6, and 9 mmol with variation of hydrothermal temperature of 140,
160 and 180 °C for 10 hrs. SEM images show that the morphology of Fe2O3 is
nano-ellipses with sizes between 90-200 nm. The highest specific discharge
capacity of 634 mAh/g is obtained for specimens with the addition of glycine by 9
mmol and hydrothermal temperature of 160 °C. This result demonstrates that
Fe2O3 has a high potential as anode material for lithium ion battery.
