Abstract

Elektrolit padat adalah bahan yang dapat menghantarkan ion secara efisien dalam fase padat. Bahan ini memiliki peran penting dalam berbagai aplikasi elektrokimia, termasuk baterai. Dalam penelitian ini penulis akan membuat elektrolit padat dari komposit PEO/Selulosa/ZIF-67 berbasiskan selulosa sekam padi pada aplikasi baterai lithium-ion. Penelitian ini bertujuan untuk menganalisis pengaruh fraksi komposisi PEO/Selulosa/ZIF67 terhadap struktur, morfologi, dan performa elektrokimia komposit PEO/Selulosa/ZIF67. Untuk mencapai tujuan tersebut dilakukan karakterisasi berupa Scanning Electron Microscopy dan Energy Dispersive X-Ray (SEM-EDX), X-Ray Diffraction (XRD), dan Fourier Transform Infrared Specstroscopy (FTIR) serta pengujian elektrokimia berupa Electrochemical Impedance Spectroscopy (EIS) dan Cyclic Voltammetry (CV). Berdasarkan penelitian tersebut, didapatkan bahwa sintesis komposit PEO/Selulosa/ZIF-67 berhasil dilakukan. Pada hasil uji SEM menunjukkan bahwa PEO sebagai matriks melekat pada selulosa dan hasil EDX menunjukkan adanya atom-atom seperti C, O, dan Co yang mengindikasikan komposit PEO/Selulosa/ZIF-67. Adapun morfologi dari selulosa yaitu berbentuk batang (rod), pada PEO berbentuk granula dan ZIF-67 yang berbentuk dodecahedron. Pada hasil uji XRD, munculnya puncak peak selulosa. Pada hasil uji FTIR menunjukkan adanya gugus fungsi yang sesuai pada masing-masing material yaitu gugus fungsi C-H, O-H, dan -CH2 yang merupakan gugus fungsi PEO, ZIF-67, dan selulosa. Performa elektrokimia pada sampel (7:1:2) menunjukkan performa elektrokimia terbaik dengan konduktivitas tertinggi (5,79984E-5 S/cm) dan kapasitansi tertinggi (0,079423 F). Sampel (7:1,5:1,5) memiliki kapasitansi spesifik tertinggi (385,41 F/m²) namun konduktivitas yang lebih rendah dibandingkan sampel lainnya. Secara keseluruhan, sampel (7:1:2) menunjukkan performa elektrokimia yang paling optimal.

Solid electrolytes are materials that can conduct ions efficiently in the solid phase. This material has an important role in various electrochemical applications, including batteries. In this study, the author will make a solid electrolyte from a PEO/Cellulose/ZIF-67 composite based on rice husk cellulose in lithium-ion battery applications. This study aims to analyze the effect of the PEO/Cellulose/ZIF67 composition fraction on the structure, morphology, and electrochemical performance of the PEO/Cellulose/ZIF67 composite. To achieve this goal, characterization was carried out in the form of Scanning Electron Microscopy and Energy Dispersive X-Ray (SEM-EDX), X-Ray Diffraction (XRD), and Fourier Transform Infrared Spectroscopy (FTIR) as well as electrochemical testing in the form of Electrochemical Impedance Spectroscopy (EIS) and Cyclic Voltammetry (CV). Based on this study, it was found that the synthesis of the PEO/Cellulose/ZIF-67 composite was successful. The SEM test results show that PEO as a matrix is attached to cellulose and the EDX results show the presence of atoms such as C, O, and Co which indicate a PEO/Cellulose/ZIF-67 composite. The morphology of cellulose is rod-shaped, PEO is granular and ZIF-67 is dodecahedron-shaped. The XRD test results show the appearance of cellulose peaks. The FTIR test results show the presence of appropriate functional groups in each material, namely the C-H, O-H, and -CH2 functional groups which are functional groups of PEO, ZIF-67, and cellulose. The electrochemical performance of the sample (7:1:2) shows the best electrochemical performance with the highest conductivity (5.79984E-5 S/cm) and the highest capacitance (0.079423 F). Sample (7:1.5:1.5) has the highest specific capacitance (385.41 F/m²) but lower conductivity than other samples. Overall, the sample (7:1:2) showed the most optimal electrochemical performance.
