Battery as an energy source for electrical component is a component that we often see and use today, but it’s development as a component of energy source can still be improved. Aluminium-air (Al-air) type of metal-air batteries are a type of batteries that are currently still being developed and has a promising potential for everyday usage. Al-air batteries need to use a catalyst on their cathodes to help oxygen reduction reaction (ORR). Development method that we could do is to make a catalyst for the cathode of the Al-air batteries derived from nut shell and FeCo alloys. In this research, we will discussed about the synthesis of cathode using carbon specimens derived from biomass materials from peanut skins and pistachio nut skins with the addition of FeCo alloys. Carbon specimens will then be tested using physical characterization and electrochemical characterization with certain methods to determine their properties. In addition, performance test for the specimens of the Al-air battery was also carried out to determine the final capacity of each specimen Al-air battery testing using specimen derived from nut shells and FeCo alloys proven to have good results From the test it was concluded that carbon synthesis was successfully carried out and the addition of FeCo alloys resulted in an increase in the properties of carbon specimens. In addition, the test results showed that the battery with pistachio nut skin specimens and FeCo alloys had the highest capacity with a value of 881.56 mAh / g.
