Abstract
Meningkatnya peminat akan baterai ion Litium menyebabkan meningkatnya kebutuhan akan Litium sebagai sumber utama. Baterai sodium menjadi alternatif untuk digunakan sebagai penyimpanan energi karena biaya bahan yang murah dan mudah didapatkan di sekitar. Elektroda pada baterai karbon ganda terdiri dari bahan karbon. Tempurung kelapa mengandung karbon yang berasal dari alam yang memiliki sifat murah, dapat diperbaharui, dan menjadi bahan elektroda yang baik. Tempurung kelapa ini kemudian diubah menjadi berbasis Hard Carbon sebagai elektroda pada baterai karbon ganda. Dilakukan pengujian XRD, FTIR, SEM, dan XPS untuk mengetahui struktur dan komposisi tempurung kelapa. Hasil pengujian XRD menunjukkan jarak kisi pada Karbon A, Karbon B, dan Hard Carbon hampir mendekati yaitu sebesar 3,9 Å, 3,8 Å, dan 4,0 Å dan nilainya lebih besar dari jarak kisi milik grafit pada baterai Litium yang sebesar 3,4-3,6 Å. Pada uji FTIR, pola grafik puncak-puncak transmisi spektrum inframerah pada Karbon A, Karbon B, dan Hard Carbon memiliki kemiripan posisi bilangan gelombang. Pada uji SEM, rata-rata distribusi ukuran partikel pada masing-masing karbon A, karbon B, dan Hard Carbon adalah 13,5 µm, 22,2 µm, dan 8,0 µm. Ketiga sampel menunjukkan terdapat pori-pori pada sampel dan bentuk partikel yang tidak beraturan. Uji XPS menunjukkan Karbon B, spektrum XPS pada puncak 292,7 eV dikaitkan dengan ikatan

The increasing interest in Lithium ion batteries has led to an increasing need for Lithium as the primary source. Sodium batteries are an alternative to use as energy storage because the cost of materials is cheap and easy to get around. The electrode on a dual carbon battery is made up of carbon materials. Coconut shell contains carbon that comes from nature which is cheap, renewable, and makes a good electrode material. The coconut shell is then converted to Hard Carbon-based electrodes in the dual carbon battery. XRD, FTIR, SEM, and XPS tests were carried out to determine the structure and composition of the coconut shell. The results of the XRD test show that the lattice spacing on Carbon A, Carbon B, and Hard Carbon is almost close, namely 3,9 Å, 3,8 Å, and 4,0 Å and displays greater than the lattice spacing of graphite on Lithium batteries which is 3,4-3,6 Å. In the FTIR test, the graphic patterns of the transmission peaks of the infrared spectrum on Carbon A, Carbon B, and Hard Carbon have similar wave positions. In the SEM test, the average particle size distribution for each carbon A, carbon B, and Hard Carbon was 13,5 μm, 22,2 μm, and 8,0 μm. The three samples showed the presence of pores in the samples and irregular particle shapes. The XPS test shows Carbon B, XPS spectrum at 292,7 eV peak associated with π-π* bonds, ~287,1 eV peak associated with C=O bond, and C=C bond at ~284,5 eV peak. Whereas on Hard Carbon, the first peak of ~288,3 eV corresponds to the C=O bond, the peak of ~290,9 eV is associated with the π-π* bond and the C=C bond corresponds to the peak of 284,6 eV
