Abstract
Due to its abundant availability and classification as biomass, the focus in renewable energy is currently centred on the use of Oil Palm Empty Fruit Bunches (OPEFB) as an alternative material for carbon production that can be used in many applications, one of which is batteries. The type of battery that is trying to use is a primary battery. The purpose of this study is to determine the effect of different concentrations of NaOH activation and immersion time on OPEFB activated carbon by analyzing the result of surface area, morphology, and electrical properties. The study found that 1 M NaOH concentration and an 18-hour immersion time were optimal, producing a surface area of 281.96 m²/g and a voltage of 0.785 V. These findings align with and contribute to existing research on biomass utilization in energy storage, demonstrating the potential of OPEFB-activated carbon in battery applications and highlighting the significance of further research in this area to enhance battery performance and scalability.
