Abstract
Baterai sebagai perangkat penyimpanan energi semakin banyak dikembangkan pada saat ini. Sodium Ion Battery (SIB) adalah salah satu kandidat yang dapat menggantikan baterai ion litium yang merupakan baterai isi ulang yang paling populer untuk peralatan elektronik portabel. Beberapa keunggulan baterai ion natrium dibanding baterai ion litium adalah harganya lebih murah, ketersediaan yang luas serta memiliki potensi untuk memenuhi kebutuhan penyimpanan energi jaringan skala besar. Pada penelitian ini Co(NO3)2, Fe(NO3)2 dan NaNO3 digunakan sebagai prekursor dalam proses sintesis Na0,628Fe0,03Co0,97O2 dengan menggunakan metode sol-gel serta variasi temperatur kalsinasi untuk mengetahui pengaruhnya terhadap struktur kristal, morfologi dan performa elektrokimia dari baterai. Variasi temperatur yang digunakan pada penelitian ini adalah 700, 750 dan 800oC. Berdasarkan hasil uji karakterisasi didapatkan bahwa pengaruh temperatur kalsinasi pada ketiga variasi telah membentuk struktur hexagonal dengan semakin meningkatnya temperatur kalsinasi ukuran kristal yang dihasilkan semakin besar. Berdasarkan hasil uji performa elektrokimia didapatkan hasil bahwa baterai ion natrium dengan katoda Na0,628Fe0,03Co0,97O2 dengan variasi temperatur 700oC memiliki performa paling baik diantara yang lainnya yaitu kapasitas spesifik 0,5219 mAh/g, coulumbic efficiency yang lebih baik sebesar 35,96% dan nilai charge transfer resistance (Rct) terkecil dengan nilai 1,676x108 Ohm.

Batteries as energy storage devices are increasingly being developed at this time. Sodium Ion Battery (SIB) is one candidate that can replace lithium ion battery which is the most popular rechargeable battery for portable electronic equipment. Some of the advantages of sodium ion batteries over lithium ion batteries are their lower cost, wide availability and potential to meet the energy storage needs of large-scale grids. In this study, Co(NO3)2, Fe(NO3)2 and NaNO3 were used as precursors in the Na0,628Fe0,03Co0,97O2 synthesis process using the sol-gel method and variations in calcination temperature to determine their effect on the crystal structure, morphology and electrochemical performance of the battery. The temperature variations used in this study were 700, 750 and 800oC. Based on the results of the characterization test, it was found that the influence of the calcination temperature on the three variations had formed a hexagonal structure with increasing calcination temperature the resulting larger crystal size. Based on the results of the electrochemical performance test, it was found that the sodium ion battery with a Na0.628Fe0.03Co0.97O2 cathode with a temperature variation of 700oC had the best performance among the others, namely a specific capacity of 0.5219 mAh/g, a better coulumbic efficiency of 35.96 % and the smallest charge transfer resistance (Rct) value of 1.676x108 Ohm.
