Danang Adiyoga C.B, Danang Adiyoga C.B (2019) Optimasi Baterai Statis Dan Dinamis Asam Timbal Tiga Sel Dengan Variasi Konsentrasi Elektrolit. Sarjana thesis, Universitas Brawijaya.
Abstract
Telah dibuat baterai dinamis dengan elektrolit H2SO4 dan elektroda Pb-PbO2 yang mengalir menuju baterai secara kontinu. Pada penelitian digunakan baterai tiga sel dengan arus pengisian 1,0 A dan pengosongan 0,5 A selama 10 siklus pada berbagai variasi konsentrasi elektrolit. Variasi yang digunakan adalah elektrolit H2SO4 dengan konsentrasi 30%; 35%; dan 40% pada masing-masing baterai statis dan dinamis asam timbal. Hasil peneltian memperlihatkan bahwa baterai dinamis tiga sel secara umum menghasilkan tegangan cut-off sebesar 7,21 V dan 5,41 V pada masing-masing proses pengisian dan pengosongan. Baterai dinamis dengan konsentrasi elektrolit H2SO4 sebesar 30% memiliki kapasitas pengisian dan pengosongan rata-rata terbesar yaitu 6689 mAh dan 5723 mAh dalam durasi 70,4 jam. Sementara itu, pada konsentrasi elektrolit H2SO4 sebesar 40% memiliki nilai kapasitas pengisian pengosongan rata-rata terkecil masing-masing bernilai 2268 mAh dan 1255 mAh . Selain itu, efisiensi rata-rata pada baterai dinamis dengan konsentrasi elektrolit H2SO4 sebesar 30% dengan prosentase 83,89%. Pada proses pengisian dan pengosongan baterai, terjadi perubahan struktur elektroda dari Pb menjadi PbSO4. Semakin besar konsentrasi elektrolit H2SO4 maka semakin besar pula prosentase pembentukan PbSO4 .
English Abstract
Dynamic batteries have been made with H2SO4 electrolytes and Pb-PbO2 electrodes which flow towards the battery continuously. Three cell batteries were used in this research with a charging current of 1,0 A and discharging current 0,5 A for 10 cycles in various electrolyte concentration. The variation used were is H2SO4 electrolyte with a concentration of 30%; 35%; and 40% on each lead acid and dynamic battery. The results show that the three cell dynamic battery generally produced 7,21 V of charging cut-off voltage and 5,41 V in the end of discharging process. .Dynamic battery with 30% electrolyte concentration of H2SO4 has the highest average charging and discharging capacity of 6689 mAh and 5723 mAh in 70,4 hours duration. For 5 cycle the battery filled with 40% H2SO4 resulted the smallest capavity respectively 2268 mAh and 1255 mAh. In addition, the average efficiency of the dynamic battery with 30% H2SO4 electrolyte concentration reach a percentage of 83,89%. In the process of charging and discharging the battery, the electrode structure changes from Pb to PbSO4. The greater the concentration of electrolyte H2SO4, the greater the percentage formation of PbSO4.
