Abstract

Hard carbon-like berbasis biomassa merupakan salah satu material karbon yang berpotensi sebagai anoda baterai ion sodium karena memiliki struktur turbostratik dengan jarak antar lapisan karbon yang lebih besar dibandingkan grafit. Penelitian ini bertujuan menganalisis pengaruh variasi suhu karbonisasi terhadap perubahan gugus fungsi, keteraturan struktur, tingkat ketidakteraturan, derajat grafitisasi, serta potensi hard carbon-like berbasis sekam padi sebagai material anoda baterai ion sodium. Material disintesis melalui proses pra-karbonisasi pada suhu 500°C selama 3 jam, kemudian dikarbonisasi pada suhu 700°C, 800°C, 900°C, dan 1000°C selama 3 jam. Karakterisasi dilakukan menggunakan Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), dan Spektroskopi Raman. Hasil FTIR menunjukkan bahwa peningkatan suhu karbonisasi menyebabkan berkurangnya intensitas gugus fungsi yang mengandung oksigen akibat proses dehidrasi, deoksigenasi, dan aromatisasi. Analisis XRD menunjukkan bahwa seluruh sampel memiliki struktur turbostratik khas hard carbon-like dengan perubahan parameter struktur berupa jarak antar lapisan karbon (d002), jarak antar bidang kristal (d100), tinggi kristalit (Lc), dan lebar kristalit (La) seiring peningkatan suhu karbonisasi. Hasil Raman menunjukkan penurunan rasio AD1/AG, AD3/AG, dan ADall/AG hingga suhu 900°C yang mengindikasikan berkurangnya cacat struktur dan meningkatnya keteraturan domain karbon sp². Berdasarkan hasil karakterisasi FTIR, XRD, dan Raman, sampel RH-900 menunjukkan karakteristik struktur yang paling optimal sehingga berpotensi sebagai kandidat material anoda baterai ion sodium.

Biomass-derived hard carbon-like is considered a promising anode material for sodium ion batteries owing to its turbostratic structure, which provides a larger interlayer spacing than graphite and facilitates sodium-ion storage. This study investigated the effect of carbonization temperature on the evolution of functional groups, structural ordering, structural disorder, graphitization degree, and the potential of rice husk-derived hard carbon-like as an anode material for sodium-ion batteries. The material was synthesized through a pre-carbonization process at 500°C for 3 h, followed by carbonization at 700°C, 800°C, 900°C, and 1000°C for 3 h. Structural characterization was performed using Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and Raman spectroscopy. FTIR analysis revealed a gradual reduction in oxygen-containing functional groups with increasing carbonization temperature due to dehydration, deoxygenation, and aromatization. XRD results confirmed that all samples exhibited a typical turbostratic hard carbon-like structure, accompanied by changes in the interlayer spacing (d002), in-plane lattice space (d100), crystallite height (Lc), and crystallite width (La). Raman spectroscopy showed a decrease in the AD1/AG, AD3/AG, and ADall/AG ratios up to 900°C, indicating reduced structural defects and improved ordering of sp² carbon domains. The combined FTIR, XRD, and Raman analyses demonstrate that the RH-900 sample exhibits the most favorable structural characteristics, indicating its potential as a candidate anode material for sodium-ion batteries.
