摘要： The present invention relates to a method for manufacturing activated carbon using a coffee bean extract, and an electrode for a battery comprising same. The method for manufacturing activated carbon, according to the present invention, is safe for the human body by using an extract obtained from food, such as coffee beans, as an activation catalyst when carbidizing cellulose, and allows easy maintenance and repair of processing equipment, thereby providing the advantages of excellent productivity, economic feasibility, and also of being environmentally friendly due to utilization of discarded food waste. In addition, activated carbon manufactured by the method has a large specific surface area and has fine pores having a diameter of no more than 2 nm, thereby being useful when applied to electrode materials for a super capacitor, among others.
