Analisis Pengaruh Ukuran Pori Terhadap Sifat Listrik Karbon Aktif Dari Limbah Tandan Sawit Pada Prototipe Baterai

Abstract

The prototype batteries was succesfully made by using activated carbon. This research aimed to examine the effect of pore size on the electrical properties of activated carbon which is used as a battery-making material. Activated carbon is synthesized using H3PO4 activator with concentration variations (mass/volume) of 5%, 10%, 15%, 20%, and 25%. The carbonization was carried out at 400 °C for 1 hour, while activation at 700 °C for 1 hour. The result showed, the pore size effect on the electrical properties of the activated carbon in the battery prototype, especially for the capacitance and internal resistance of the material which has a correlation of 90% and 90.2%, respectively. The sample with 25% H3PO4 has the best pore size of 5.43μm. As the pore size of the activated carbon increases, it has caused increased capacitance and decreased internal resistance of the material. With the pore size of 5.43μm, the capacitance is 5.88mF/g and the internal resistance of the material is 662.02Ω.

CHARACTERIZATION OF SALAK WEDI ACTIVATED CARBON STRUCTURE USING KOH AND ZnCl2 ACTIVATOR

“…However, the pore distribution of these four samples is still uneven. This may also be due to the nonflowing nitrogen gas during the carbonization process which also affects the uneven distribution of pores on the surface of the activated carbon of the bark [11]. In addition, the SEM results obtained that the multilevel activation has a larger number of pores compared to the activation which is only carried out once, with the result that the largest pore volume with the stratified activator Carbon KOH + ZnCl2(s) is 35,976,798,714 nm 3 .…”

Analisis Morfologi dan Struktur Karbon Aktif Kulit Salak Wedi dengan Aktivator Bertingkat

“…Karbon aktif merupakan salah satu jenis bahan yang secara luas telah digunakan karena memiliki luas permukaan yang tinggi, ketahanan kimia, konduktivitas listrik yang baik dan harga yang terjangkau [3]. Karbon aktif merupakan sebuah bahan yang mengandung karbon bebas cukup besar, dimana karbon bebas tersebut memiliki daya serap yang tinggi dan memiliki pori yang meningkatkan daya serapnya karena mengalami reaksi dengan bahan kimia sebelum atau sesudah karbonisasi [4].…”

“…The activation process can remove impurities on the activated carbon surface. The more impurities lost during the activation process cause the pore size of the activated carbon to increase [17]. The results of SEM images with a magnification of 5000 times were used for pore size analysis.…”
