abstract: Industri baterai lithium-ion mengalami pertumbuhan yang signifikan dalam beberapa tahun terakhir. Dalam konteks sistem penyimpanan energi, Lithium ion battery (LIB) adalah teknologi penyimpanan energi elektrokimia yang paling canggih, digunakan dalam berbagai aplikasi seperti perangkat seluler, otomotif, dan elektronik lainnya. Material anoda merupakan bagian penting dari baterai lithium, material anoda yang paling banyak dikomersialkan adalah grafit. Salah satu material yang dapat digunakan untuk aplikasi anoda pada baterai lithium-ion adalah timah oksida (SnO2). Penelitian ini bertujuan untuk membuat serbuk komposit SnO2@rGO yang dibuat dengan cara memanfaatkan limbah grafit elektroda EAF (Electric Arc Furnace). Kemudian dilakukan reaksi Hummers untuk menghasilkan serbuk Grafena Oksida (GO). Setelah serbuk GO didapatkan kemudian serbuk GO dengan berat 4, 5, dan 6 gram disintesis dengan serbuk timah dengan menggunakan H2SO4 dan H3PO4 sebagai pelarut dengan variasi konsentrasi 100%H2SO4, 50%H2SO4:50%H3PO4, dan 100%H3PO4. GO kemudian tereduksi menjadi rGO (reduced Graphene Oxide) dan timah akan teroksidasi menjadi timah oksida dan timah fosfat. Setelah itu serbuk komposit timah/rGO dilakukan pengujian SEM (Scanning Electron Microscopy), XRD (X-ray Diffraction), dan pengujian sifat elektrokimia. Pada analisis XRD menunjukkan identifikasi empat fasa senyawa pada serbuk yang dihasilkan yaitu SnO2, rGO, SnS, dan Tin (II) Pyrophosphate. Nilai Rs dan Rct dari pengujian EIS yang terbaik terdapat pada sampel Z dikarenakan nilai Rs dan Rct yang didapatkan terendah.
