Abstract
Baterai LiFePO4 (LFP) atau lithium ferro phospate merupakan bagian dari baterai Li�Ion. Sedangkan solvent yang dipakai di sini adalah Choline Chloride (ChCl) dan Urea
dimana merupakan bagian dari DES tipe 3. Deep Eutectic Solvent (DES merupakan pelarut
ramah lingkungan yang memiliki banyak fungsi. Penelitian tentang pemisahan
Polyvinilidefluoride (PVDF) dari katoda dengan DES terbilang sangat minim dan masih
belum ada yang meneliti tentang penggunaan ChCl + urea untuk pemisahan PVDF baterai
LFP dari katodanya. Penelitian ini bertujuan untuk mengetahui pengaruh molar rasio,
temperatur dan waktu dari solvent ChCl + Urea terhadap optimasi pemisahan PVDF dari
katoda baterai LFP bekas. Baterai LFP bekas ini didapatkan dari workshop baterai GESITS
Surabaya, baterai bekas didapatkan kemudian di discharge untuk menghilangkan tegangan
yang tersisa. Selanjutnya didismantle, untuk diambil katodanya. Kemudian katoda dipotong
dengan ukuran 1x1 cm lalu dileaching dengan variasi molar ratio ChCl Urea (1:2), dengan
variasi temperatur (170, 190, 210) dan waktu (2, 3, 4 jam) . Penentuan temperatur ini
didasarkan atas perhitungan menggunakan metode diagram eutektik, untuk menentukan
temperatur eutektiknya. Pengujian yang dilakukan yaitu SEM, XRD, FTIR, dan EDX.
Peeling percentage yang didapatkan adalah untuk variasi dari temperatur dan waktu terkecil
ke terbesar berturut-turut adalah sebagai berikut: 72,75%, 78,62%, 85,67%, 88,46%, 95,07%,
93,63%, 90,80%, 87,70%, 86,95%. Hasil SEM menunjukkan bahwa semakin tinggi
temperatur dan waktu de-bonding maka partikel semakin teraglomerasi. Dan variasi optimal
untuk mendapatkan persentase pengotor terendah dari pengujian EDS adalah variasi 190 C, 4
jam dengan persentase Al sebesar 1,31%.
==================================================================
LiFePO4 (LFP) or lithium ferro phosphate batteries are part of the Li-Ion battery.
Meanwhile, the solvents used here are Choline Chloride (ChCl) and Urea which are part of
DES type 3. Deep Eutectic Solvent (DES is an environmentally friendly solvent that has
many functions. Research on the separation of Polyvinylidefluoride (PVDF) from the cathode
with DES is very minimal. and no one has yet researched the use of ChCl + urea to separate
PVDF LFP batteries from the cathode. This research aims to determine the effect of the molar
ratio, temperature and time of the ChCl + Urea solvent on optimizing the separation of PVDF
from the cathode of used LFP batteries. This used LFP battery obtained from the GESITS
Surabaya battery workshop, the used battery was obtained then discharged to remove the
remaining voltage. Next it was dismantled, to take the cathode. Then the cathode was cut to a
size of 1x1 cm then leached with variations in the ChCl Urea molar ratio (1:2), with
temperature variations (170, 190, 210) and time (2, 3, 4hours). Determination of this
temperature is based on calculations using the eutectic diagram method, to determine the
eutectic temperature. The tests carried out were SEM, XRD, FTIR, dan EDX. The peeling
percentages obtained for variations from smallest to largest temperature and time are as
follows: 72.75%, 78.62%, 85.67%, 88.46%, 95.07%, 93.63% , 90.80%, 87.70%, 86.95%.
SEM results show that the higher the temperature and de-bonding time, the more
agglomerated the particles are. And the optimal variation to get the lowest percentage of
impurities from the EDS test is the 190 C, 4 hour variation with an Al percentage of 1.31%.
