Abstract

Penelitian tentang anoda baterai ion lithium sebagai sistem penyimpanan energi berkembang begitu pesat. Pada penelitian ini anoda Fe2O3 yang akan digunakan dihasilkan dari sintesis Hidrotermal FeCl3.6H2O dengan penambahan Lisin sebagai Hydrolising Controlling Agent untuk menghasilkan anoda Fe2O3 microsphere. Penelitian ini bertujuan untuk menganalisa pengaruh perbedaan konsentrasi lisin sebagai pereaksi hidrolisis terhadap performa elektrokimia anoda Fe2O3 yang dihasilkan. Variasi Lisin yang digunakan adalah 0,5 mol, 1 mol, dan 2 mol. Dari hasil pengujian diperoleh sampel dengan penambahan lisin 2 mol menghasilkan performa terbaik. Hal ini didasarkan pada kristalinitas yang baik serta bentuk morfologi microsphere yang memiliki ukuran permukaan paling kecil. Hasil pengujian charge/discharge yang menunjukan kapasitas spesifik mencapai 121.89 mAH/gr pada siklus pertama dan hanya mengalami capacity fading sebesar 28% serta menghasilkan charge transfer resistance yang cukup rendah mencapai 109.31 Ω. ========== Research on the anodes of lithium ion batteries as the energy storage system has developed so fast. In this study Fe2O3 would be used as anode which was produced from FeCl3.6H2O Hydrothermal synthesis with the addition of lysine as Hydrolising Controlling Agent. The main aim of lysine addition was producing anode of Fe2O3 microspheres. This study aimed to analyze the effect of lysine addition in different concentrations. Lysine took an important role as hydrolysis reactants of the electrochemical performance of the anode Fe2O3 generated. Lysine variation used was 0.5 mol, 1 mol and 2 mol. From the test results of samples obtained by adding 2 mol lysine produces the best performance. It was based on a good crystallinity, and morphology of the surface of the microsphere has the smallest size. Moreover, the results of discharge testing, the specific capacity reached 121.89 mAh / g in the first cycle and only experienced a fading capacity by 28% and generate charge transfer resistance low enough reach 109.31 Ω.
