Abstract

Telah dilakukan sintesis material anoda baterai litium dari litium hidroksida (LiOH) dan karbon aktif. Pembuatan karbon aktif dilakukan dengan aktivasi kimia dari arang kemiri menggunakan H3PO4 2,5 % sebagai aktivator pada temperatur aktivasi 600 ºC. Karbon aktif dikarakterisasi menggunakan SEM. Selanjutnyadilakukan pembuatan material anoda dengan menggunakan metode sol-gel dengan variasi konsentrasi LiOH 0,2 g; 1 g; 1,5 g dan 2 g. Material anoda dibuat dalam bentuk pelet dan dikarakterisasi menggunakan X-ray Diffraction (XRD), LCR meter dan Cyclic Voltammetry (CV). Hasil SEM menunjukkan bahwa pori karbon aktif tersebar hampir merata, dan berdasarkan hasil XRD, semua sampel memiliki fasa carbon (C) dengan struktur kristal hexagonal. Konduktivitas dan kapasitansi maksimum yang diperoleh pada konsentrasi LiOH 1,5 g sebesar (2,34x10-6 ) S/cm dan 327,93 μF.
