Abstract

Karbon berbasis Tandan Kosong Kelapa Sawit (TKKS) dimanfaatkan sebagai material anoda pada prototipe baterai pouch cell dan dimodifikasi menggunakan silika geotermal (SiO2-G) untuk meningkatkan karakteristik material serta performa elektrokimianya. Proses sintesis diawali dengan aktivasi kimia menggunakan FeCl₃, kemudian dilanjutkan dengan karbonisasi pada temperatur 700, 750, 800, 850, dan 900°C selama 1 jam. Setelah karbon terbentuk, dilakukan doping SiO2-G melalui metode impregnasi. Karakteristik material dianalisis menggunakan FTIR, SEM-EDX, dan BET, sedangkan kinerja elektrokimia dievaluasi melalui pengujian CV, CD, dan EIS. Berdasarkan hasil yang diperoleh, sampel SiO2-G/C pada temperatur karbonisasi 850°C memberikan performa paling optimal dengan luas permukaan spesifik mencapai 919,02 m2/g. Peningkatan karakteristik tersebut diikuti oleh capaian kapasitas spesifik sebesar 527,78 mAh/g, tegangan baterai sebesar 3,29 V, waktu charge-discharge selama 6 jam 20 menit, serta nilai hambatan elektroda terendah sebesar 18,74 Ω.
