Analisis Performa Baterai Air Laut Menggunakan Elektroda Cu-Zn

Abstract

One source of energy that can be used as an alternative energy is the battery, where in a battery there is a voltaic cell reaction, is a chemical reaction that is spontaneous and can produce an electric current, where the cathode as a positive tick while the anode as a negative tick. In this thesis, research was conducted on the characteristics of seawater batteries, using seawater as a solution, this is in accordance with one of the conditions for the reaction of volta cells to be done if in the dissolve must have positive ions (cations) and negative ions (anions), where in seawater contained NA+ and CL- ions, while for the electrodes use Zn-Cu, metals on Zn and Cu that become positive and negative electrodes, this is due to the release of electrons that occur. Due to oxidation reactions in the Zn metal, the reduction reaction in the Cu metal is therefore the Zn metal can be said to be an anode (negative pole) and Cu is said to be a cathode (positive pole). In testing, a single configuration, 2 series configuration, and 2 parallel configuration are carried out. From this study, the results of the open voltage test of the single configuration battery were 0.75V and there was a decrease to 0.76V at minute 1 120, the results of the open voltage test of the 2 series configuration battery were 1.48V and there was a decrease to 1.46V at minute 120, the results of the open voltage test of the 2 parallel configuration battery were 0.74 V and there was a decrease to 0.73V at minute 120, the results of the single configuration battery current test with a load of 1 were The voltage is 0.73V, the current is 0.16A, and the resistance is 3.5625 the voltage is 0.70V, the current is 0.10, while the resistance is increased to 6 at the minute of 120, the results of the battery current test configuration 2 series with a load of 1 are 1.41V, the current is 0.16A, and the resistance is 7.812 to 0.70V, the current is 0.08, while the resistance is increased to 16.375at the minute of 120, and the results of the single configuration battery current test with a load of 1⁗ are the voltages. 0.73V, 0.24A current, and 2.041 resistance decrease to 0.69V voltage, 0.21A current while the resistance increases to 2,285 at 120 minutes
