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.
