An electrochemical battery runs out when all the chemicals inside have finished the current-releasing chemical reactions. In this work, an air battery system is designed and studied using Sodium Chloride (NaCl) and Caustic Potash (KOH) electrolytic solution.The battery life of the designed air battery system is studied in terms of voltage capacity for a period of 4 weeks and 4 days (750 hours) for two air batteries connected in series. As the electrolytic chemicals are being used up when the battery is in operation, it was observed that voltage rating degraded over time even when the battery system is not connected to a load. From the results, an air battery with KOHelectrolytic solution produced a higher voltage compared with NaCl electrolytic solutionapplication/pdfTK Electrical engineering.
