Abstract
The lithium-ion battery industry is rapidly evolving, with tin oxide (SnO2) emerging as a potential material for anodes. This research aims to develop an anode composite for lithium-ion batteries based on tin oxide (SnO2) and graphene oxide (GO). The SnO2@GO composite powder was produced using graphite electrode waste from an EAF that was milled for 5, 10, and 15 hours, then processed through the Hummers reaction to produce GO. Subsequently, the GO powder was synthesized with tin powder using H2SO4 as the solvent, with varying GO concentrations of 1 mg/ml, 2 mg/ml, and 3 mg/ml. The GO was reduced to rGO (reduced Graphene Oxide), and the tin was oxidized to tin oxide. SEM tests showed that particles with longer milling times tend to have a more rounded shape and smaller size. At 5 hours of milling, the average particle sizes were 1.41 µm, 1.163 µm, and 1.189 µm. After 10 hours of milling, the particle sizes were 1.118 µm, 1.032 µm, and 0.959 µm, while at 15 hours, the particles became more rounded with sizes of 0.929 µm, 1.01 µm, and 0.836 µm. The conductivity of the composite showed the highest values at a GO concentration of 3 mg/ml, with results of 1.26 S/m, 2.339 S/m, and 0.447 S/m. XRD analysis identified two dominant compound phases: SnO2 with a tetragonal crystal structure and peak positions at 27.10894°, 39.20363°, 26.27141° and rGO with a monoclinic crystal structure and peak positions at 25.31639°, 24.38903°, 23.86739°.

| Additional Information: | Industri baterai lithium-ion berkembang pesat, dengan timah oksida (SnO2) sebagai salah satu material potensial untuk anoda. Penelitian ini bertujuan mengembangkan komposit anoda untuk baterai lithium-ion berbasis timah oksida (SnO2) dan grafena oksida (GO). Serbuk komposit SnO2@GO dibuat menggunakan limbah grafit elektroda EAF yang dimilling selama 5, 10, dan 15 jam, kemudian diolah melalui reaksi Hummers untuk menghasilkan GO. Setelah itu, serbuk GO disintesis dengan serbuk timah menggunakan H2SO4 sebagai pelarut, dengan variasi konsentrasi GO 1 mg/ml, 2 mg/ml, dan 3 mg/ml. GO tereduksi menjadi rGO (reduced Graphene Oxide) dan timah teroksidasi menjadi timah oksida. Hasil uji SEM menunjukkan bahwa partikel dengan waktu milling yang lebih lama akan menghasilkan bentuk partikel yang cenderung berbentuk rounded dan memiliki ukuran yang lebih kecil. Pada waktu milling 5 jam dengan ukuran rata-rata 1,41 µm, 1,163 µm, dan 1,189 µm. Pada waktu milling 10 jam, ukuran partikel adalah 1,118 µm, 1,032 µm, dan 0,959 µm, sementara pada 15 jam partikel menjadi rounded dengan ukuran 0,929 µm, 1,01 µm, dan 0,836 µm. Konduktivitas komposit menunjukkan nilai tertinggi pada konsentrasi GO 3 mg/ml, dengan hasil 1,26 S/m, 2,339 S/m, dan 0,447 S/m. Analisis XRD mengidentifikasi dua fasa senyawa dominan, yaitu SnO2 dengan struktur kristal tetragonal dan posisi peak pada 27,10894°, 39,20363°, 26,27141° dan rGO dengan struktur kristal monoklinik dan peak posisi pada 25,31639°, 24,38903°, 23,86739°. | |||||||||
