Bio batteries are the latest promising innovation in the world of energy technology. One interesting type of bio battery is a battery made from old coconut shell charcoal. The raw materials used have high conductive properties and porosity, enabling the absorption and release of electrons with high efficiency. Mature coconut shell charcoal has a microporous structure that allows electrolyte absorption, which can increase energy storage capacity. The research results obtained are that variations in electrolytes and electrodes greatly influence the electricity of bio-batteries made from coconut shell charcoal graphene oxide, due to the reactions that occur between the constituent elements of the metal pair as electrodes and some combinated samples as electrolyte. Where the voltage and electric current strength of the bio battery uses Graphene Oxide sample with Cu-C electrodes and electrolyte (anode layer of K2SO4 and KOH), namely 2 V and 0.2 A compared to Cu-Al electrodes and other samples. There is a relationship between variations in electrodes and variations in graphene oxide and copper oxide samples on bio-battery electricity. So, using the ratio of mixing K2SO4 and KOH will produce a greater voltage and current compared to other ratios.
