Amirullah, Ahmad Arif (2018) Pengaruh Perbedaan Luas Permukaan Elektroda Pb-Pbo2 terhadap Karakteristik Baterai Dinamis (Redox Flow Battery) dengan H2so4 sebagai Elektrolit. Sarjana thesis, Universitas Brawijaya.
Abstract
Redox Flow Battery (RFB) merupakan jenis baterai baru yang memiliki kemampuan untuk menyimpan energi yang cukup besar jika dibandingkan dengan baterai konvensional. Sistem baterai ini menggunakan pompa untuk mengalirkan elektrolit menuju sel baterai. Pada penelitian ini telah dibuat baterai dinamis (RFB) asamtimbal sel tunggal dengan variasi luasan elektroda Pb-PbO2 sebesar (31,5x7,5) cm2, (22,5x7,5) cm2, dan (13,5x7,5) cm2. Larutan asam sulfat (H2SO4) dengan konsentrsi 30% digunakan sebagai elektrolit pada baterai. Pengujian baterai dilakukan dengan metode chargedischarge sebanyak tiga siklus pada arus pembebanan 1 ampere yang dikontrol oleh battery management system (Turnigy accucell-6). Hasil percobaan menunjukkan bahwa kapasitas dan efisiensi baterai dinamis asam-timbal meningkat dengan bertambahnya luasnya elektroda. Berdasarkan hasil pengujian, baterai dengan ukuran elektroda (31,5x7,5) cm2 memiliki kapasitas dan efisiensi energi tertinggi, masing-masing sebesar 10357 mAh dan 80,94%. Bila dibandingkan dengan baterai konvensional (elektrolit statis), kapasitas baterai dinamis lebih tinggi 869 mAh, yaitu 9488 mAh pada keadaan statis dan 10357 mAh ketika elektrolit mengalir melalui sel baterai. efisiensi energi untuk keadaan statis adalah 80,29%, lebih kecil dari keadaan dinamis dengan nilai 80,94%.
English Abstract
Redox Flow Battery (RFB) is a new type of battery that has an ability to store more energy than conventional batteries. A pump is used in the system of the battery to flow the electrolyte through the battery. In this research, single cell lead acid flow batteries (RFB) with three different electrode sizes ((31.5x7.5) cm2, (22,5x7,5) cm2, and (13,5x7,5) cm2) have been developed. 30% aquous sulfuric acid is used as the electrolyte of the batteries. The battery tests were completed by a charge-discharge method for three cycles at 1 ampere load current. The tests were controlled by a battery management system (Turnigy accucell-6). Based on the experimental results, the capacity and energy efficiency of the lead acid flow battery increase along with the increasing of the electrode size. The lead-acid flow batteries have a higher capacity and energy efficiency than the conventional batteries. For the batteries with the largest electrode size, the capacity of the dynamic state (flow) battery is 10357 mAh, which is 869 mAh higher than the static state (conventional) battery's. The energy efficiency of the static state battery 80.29%, smaller than the dynamic state battery's. The dynamic state battery's energy efficiency is 80,94%.
