Gobay, Levinus (2019) Analisis Siklus Charging-Discharging Baterai Dinamis Asam Timbal Dengan Variasi Kelajuan Alir Elektrolit. Sarjana thesis, Universitas Brawijaya.
Abstract
Baterai yang mampu menyimpan banyak muatan, murah dan mudah dirawat, adalah salah satu kebutuhan utama saat ini. Penelitian telah dilakukan pada baterai asam timbal dinamis sel tunggal 4 aliran elektrolit (45 mL/menit, 77 mL/menit, 90 mL/menit, 105 mL/menit), konsentrasi 30% dan 40% dengan tujuan menganalisis efek aliran elektrolit pada kinerja baterai. Percobaan dilakukan dengan metode siklabilitas di mana arus 1 A diterapkan selama pengujian hingga mencapai tegangan cut-off. Hasil percobaan dalam bentuk tegangan, arus, dan kapasitas secara real-time menunjukkan bahwa semua baterai dapat diisi ulang. Tegangan kerja baterai memiliki kisaran 1,8 V hingga 2,4 V. Aliran elektrolit dapat mempengaruhi durasi siklus, jumlah siklus, tegangan awal, dan kapasitas baterai. Pada konsentrasi 30% dan 40% asam sulfat, menunjukkan bahwa semakin tinggi laju aliran elektrolit menghasilkan durasi dan kapasitas yang lebih tinggi pada awal siklus tetapi menurun dengan meningkatnya jumlah siklus. Konsentrasi elektrolit 30% dalam sistem RFB asam-timbal memiliki kinerja yang lebih baik pada semua variasi laju aliran elektrolit dibandingkan dengan konsentrasi asam sulfat 40% dengan nilai terbaik pada kecepatan 45 mL/menit dalam hal lifetime dan 90 mL/menit dalam hal kapasitas baterai.
English Abstract
A battery that is capable of storing a lot of charges, cheap and easy to maintain, is one of the main needs today. Research has been carried out on single-cell dynamic lead acid batteries 4 electrolyte flow (45 mL/minute, 77 mL/minute, 90 mL/minute, 105 mL/minute), 30% and 40% concentrations with the aim is analyzing the effect of electrolyte flow on battery performance. The experiment was carried out by cyclability method where 1 A current applied during the test until it reached the cutoff voltage. The experimental results in the form of voltage, current, and capacity in real-time show that all batteries were rechargeable. The working voltage of the battery had a range of 1.8 V to 2.4 V. The electrolyte flow to be able to influence the duration of the cycle, number of cycles, initial voltage, and battery capacity. At concentrations of 30% and 40% sulfuric acid, shown that the higher the electrolyte flow rate resulted in higher duration and capacity at the beginning of the cycle but decreases with the increasing number of cycles. The electrolyte concentration of 30% in the lead-acid RFB system had better performance on all electrolyte flow rate variations compared to the 40% concentration of sulfuric acid with the best value at speeds of 45 mL/minute in terms of lifetime and 90 mL/minute in terms of battery capacity.
