Design and Construction of Redox Flow Battery using Liquid Extract from Morinda Lucida Leaves

Abstract

The research is focused on the use of a liquid extract from morinda lucida leaves as electrolyte in the construction of a redox flow battery using fired clay pot as the separating medium. After the Soxhlet extraction, each of the liquid electrolyte was stored in a container for each half-cell, and the electrode was dipped into the electrolyte. For cell testing and charging, a wire was connected to the top of the electrodes. A 3V battery was used to charge the cell, a maximum discharge voltage of 1.31V and a maximum discharge current of 13mA were recorded from the battery testing results. Results showed that the liquid extract from morinda lucida leaves as a good conductor of electricity and a suitable electrolyte for a redox flow battery.
