INVESTIGATING THE PROBIOTIC ELECTROLYTE MEDIUM IN MAGNESIUM-STAINLESS STEEL-PAIRED BATTERY

Although batteries have been a reliable power source for decades, there may be an alternative type of battery that is cheaper and equally, if not more, efficient and reliable relative to common batteries used today. Electrolyte batteries use a pair of electrodes that transfer electrons through an aqueous medium, such as salt water. A multitude of documented studies have focused on the types of electrode pairs, but the effects of the aqueous medium on electric potentials have not been well characterized. A four-channel data acquisition system monitored the electric generation patterns from the electrochemical batteries changing pairs of electrodes.

The study found that the pair of magnesium ribbon-type electrode and stainless steel electrode generated the highest electrical potential among multiple pairs tested. The following aqueous mediums were examined such as salt water, probiotic material, organic medium, and alkaline solution. Of these, the probiotic material had the highest peak in electrical potential at approximately 2V. The peak in the electrical potential waveforms with probiotic material were increased with concentration and temperature. Not a significant change in electrical potential was confirmed with the stirring force. The results might contribute to the comprehensive understanding of the factors influencing electrical potentials in biochemical batteries.
