Abstract
Tin phosphate can be used for electrolyte applications. The solid electrolyte industry has experienced significant growth in recent years. In 2020, the market size of the solid electrolyte industry was estimated at $17.8 million and is expected to reach $56.6 million by 2030 at a CAGR of 12.1% from 2021 to 2030. The growth of the solid electrolyte industry is driven by the growing demand for solid batteries. Solid batteries are becoming a promising alternative to conventional lithium-ion batteries. This study produced tin phosphate nanoparticles through the synthesis of tin phosphate/GO by modification of the Hummers reaction, using the GO template method used to control the morphology and crystal structure of the synthesized material, and calcined to remove GO and produce tin phosphate powder. The results show that the milling time of graphite affects the size of the tin phosphate powder produced, and the size of the graphene oxide (GO) template also affects the size of the tin phosphate powder. The milling time also affects the weight of the powder before and after calcination, as well as the amount of GO and tin phosphate produced. The ratio of graphite addition also significantly affects the weight of tin phosphate/GO samples before and after calcination. The addition ratio of 2 grams of graphite to 1 gram of tin produced the optimal weight of tin phosphate after calcination, showing the effectiveness of using GO as a tin growth template. In addition, XRD analysis showed the identification of three dominant compound phases in the resulting powder, namely potassium ditin (IV) tris(phosphate (V)) (KO12P3Sn2), tin phosphate (SnP2O7), and potassium ferrate (FeKO2).

| Additional Information: | Timah fosfat dapat digunakan untuk alplikasi elektrolit. Industri elektrolit padat mengalami pertumbuhan yang signifikan dalam beberapa tahun terakhir. Pada tahun 2020, ukuran pasar industri elektrolit padat diperkirakan mencapai $17,8 juta dan diperkirakan akan mencapai $56,6 juta pada tahun 2030 dengan CAGR sebesar 12,1% dari tahun 2021 hingga 2030. Pertumbuhan industri elektrolit padat didorong oleh permintaan yang meningkat untuk baterai padat. Baterai padat menjadi alternatif yang menjanjikan untuk baterai ion litium konvensional. Penelitian ini menghasilkan timah fosfat nanopartikel melalui sintesis timah fosfat/GO dengan modifikasi reaksi Hummers, menggunakan metode template GO yang digunakan untuk mengontrol morfologi dan struktur kristal dari bahan yang disintesis, dan dikalsinasi untuk menghilangkan GO dan menghasilkan serbuk timah fosfat. Hasil penelitian menunjukkan bahwa waktu milling grafit mempengaruhi ukuran serbuk timah fosfat yang dihasilkan, dan ukuran template Grafena Oksida (GO) juga mempengaruhi ukuran serbuk timah fosfat. Waktu milling juga mempengaruhi berat serbuk sebelum dan sesudah kalsinasi, serta jumlah GO dan timah fosfat yang dihasilkan. Rasio penambahan grafit juga berpengaruh signifikan terhadap berat sampel timah fosfat/GO sebelum dan setelah kalsinasi. Rasio penambahan grafit 2 gram dengan 1 gram timah menghasilkan berat timah fosfat yang optimal setelah kalsinasi, menunjukkan efektivitas penggunaan GO sebagai template pertumbuhan timah. Selain itu, analisis XRD menunjukkan identifikasi tiga fasa senyawa dominan pada serbuk yang dihasilkan, yaitu potassium ditin (IV) tris(phosphate(V)) (KO12P3Sn2), tin phosphate (SnP2O7), dan potassium ferrate (FeKO2). | ||||||||||||
