Increasing energy-requiring storage of energy. The most widely used battery is lithium-ion, but the price is expensive and less of security. The aluminium-air battery has the second largest energy density of 8100 Wh kg-1 and the obtain of aluminium on earth is abundant and inexpensive. In the other side, abundant of waste cranberry bean peel and red bean peels is proven by the production of 34,000 tons of red beans in 2017. The biomass of cranberry bean peel’s and red bean peel’s can be used as electrocatalyst in aluminium-air batteries. In this study, biomass synthesized into carbon, and then pyrolysis. Furthermore, carbon samples were given FeCo to improve battery performance, the oxygen reduction reaction occurring faster so that battery performance was better. The biomass electrocatalyst quality was tested with physical and electrochemical properties. physical properties were in the form of electrocatalyst composition, formed phases and biomass morphology. The electrochemical properties carried out were the testing of LSV, open circuit, galvanodynamic, eis (resistance) so that the battery performance data obtained. The results of the research found that carbon biomass with FeCo alloy is good to be used as an electrocatalyst because it can produce a power density of 92 mAcm-2 and capacity of 940 mAh / g to 1259 mAh / g which can be applied to several electronic types of equipment
