Abstract

Aplikasi baterai ion litium secara komersial telah tersebar luas dan meningkat seiring pertumbuhan penduduk baik di Indonesia maupun Dunia. Baterai ion litium tersusun atas katoda sulfur, separator, anoda logam litium dan elektrolit organik. Separator baterai adalah komponen penting yang berperan dalam pertukaran ion pada saat pengisian dan pemakaian baterai. Beberapa material telah dimodifikasi untuk membantu mencegah katoda berdifusi serta menjaga posisi katoda tersebut agar tetap pada posisinya sehingga mampu meningkatkan kinerja baterai. Peningkatan ion konduksi menjadi hal yang perlu diperhatikan dalam aplikasi pengisian ulang daya baterai litium. Penelitian ini bertujuan membuat bahan membran separator Polyvinylidene Fluoride - Boron Nitride – Hexafluoropropylene dengan metode inversi fasa dan metode pencampuran. Perbandingan variasi penambahan bahan adalah 1 : 2 pada masing-masing metode. Performa membran separator dilihat berdasarkan derajat kristalinitas, ukuran pori, gugus fungsi O-H dan PVdF, serta nilai konduktivitas listrik. Berdasarkan hasil interpretasi dari berbagai analisa tersebut, masing-masing metode memberikan kelebihan dan kekurangan terhadap konsentrasi bahan yang digunakan. Namun, dapat disimpulkan bahwa metode inversi fasa dapat lebih diunggulkan dalam menghasilkan produk yang lebih stabil

Abstract

The selection of a catalyst is imperative in extracting silica. Calcium is a heterogeneous base catalyst that is abundant in carbonate rocks. This study attempts to extract silica using an artificial carbonate solvent with variations of strong acid HCl (1 M, 3 M, 5 M), NaCl salt (1: 2, 1: 4) w/w ratio to distilled water, and H2O (1: 4) w/w ratio to carbonate. Characteristics of fly ash were analyzed using XRF and XRD to determine the elemental composition, crystal structure, and dominant constituent compounds. The solvent concentration and pH effect in extracting silica from fly ash is reviewed by setting the temperature parameter at 60 C, 120 minutes extraction time, and the ratio between fly ash and carbonate solvent 20 % w/v. The filtrate was verified using UV-Vis to determine the concentration of dissolved silica (SiO2) in the carbonate solvent. The examination results showed that the carbonate solvent with 3 M HCl was able to extract silica better than the other five solvents at 68.17 ppm.
