Abstract
Material anoda telah berhasil didaur ulang dari Baterai Ion Lithium (LIB) bekas menggunakan pemisahan mekanis. Limbah LIB bekas sebagian besar akan berakhir di tempat penimbunan sampah sehingga menyebabkan pencemaran tanah. Metode daur ulang secara mekanis dapat diterapkan untuk mengurangi limbah LIB bekas. Material anoda LIB bekas dikarakterisasi untuk mengetahui karakteristiknya dan dibandingkan dengan material anoda LIB baru. Penambahan grafit dilakukan untuk mengetahui pengaruhnya terhadap performa baterai. Hasil penelitian menunjukkan anoda LIB bekas memiliki struktur yang sama dengan anoda LIB baru serta cocok dengan JCPDS No. 96-901-1578 yang merupakan struktur grafit. Penambahan grafit menyebabkan arus puncak anodik semakin tinggi. Anoda LIB bekas dengan variasi penambahan grafit 0% memiliki efisiensi yang lebih baik dibanding variasi penambahan 5% grafit dari berat sampel dengan kapasitansi spesifik yang didapat sebesar 137,611 mAh/g.

The anode material has been successfully recycled from used Lithium Ion Battery (LIB) using mechanical separation. Most of the used LIB wastes will end up in landfills, causing soil contamination. Mechanical recycling methods can be applied to reduce used LIB waste. The used LIB anode material was characterized to determine its characteristics and compared to the new LIB anode material. The addition of graphite is done to determine the effect on battery performance. The results showed that used LIB anodes had the same structure as the new LIB anode and were compatible with JCPDS No. 96-901-1578 which is a graphite structure. Addition of graphite causes anodic peak flow to be higher. Used LIB anodes with variations in the addition of 0% graphite have better efficiency than the variation of adding 5% graphite with specific capacitance obtained at 137.611 mAh /g.
