Analisis Besar Tegangan Pembangkitan Baterai Air Garam terhadap Dimensi dan Jarak Elektroda Cu-Zn

Abstract

One innovation being developed in the renewable energy sector is environmentally friendly batteries, including batteries based on natural electrolyte solutions such as salt water. This study analyzes the effect of electrode dimensions and inter-electrode distance on the generated voltage in a salt water battery using copper (Cu) and zinc (Zn) electrodes, as well as the corrosion rate of the electrodes. Experiments were conducted by varying the surface area of the Cu and Zn electrodes (3 cm x 3 cm, 4 cm x 4 cm, and 5 cm x 5 cm), and the inter-electrode distances (1 cm, 2 cm, and 3 cm) in the salt water electrolyte solution. This study used a direct experimental method, with measurements made using an Arduino to obtain periodic voltage and current values. In this study, the highest voltage generated was 0.5 V in the first experiment using electrodes measuring 5 cm x 5 cm and a 3 cm inter-electrode distance. The results of the study indicate that the larger the electrode dimensions and the greater the distance between the electrodes, the higher the voltage and current values. This study also shows that Zn electrodes are more susceptible to corrosion than Cu electrodes.
