The consistent increase in plastic production is believed to increase the amount of plastic waste made. It is estimated that plastic waste that is considered to be mismanaged in Indonesia as of 2020 will reach 4.8 million tons/year, with the criteria that 48% of waste is burned, 13% is disposed of on land or unofficial landfills, and 9% into seawater. Therefore, proper waste management is needed, namely by recycling plastic waste. One of the sophisticated waste recycling is the utilization of plastic waste for renewable energy such as batteries. This study aimed to study the effect of the addition of activated carbon from plastic waste recycling on battery performance. This research was carried out by carbonizing PET plastic waste at a temperature of 400°C in an inert nitrogen atmosphere and activating the carbon yield using NaOH. Battery performance testing is carried out by testing Electrochemical Impedance Spectroscopy (EIS), Cyclic Voltammetry (CV), and Charge Discharge (CD). The EIS test shows that the addition of activated carbon can increase the anode conductivity of LTO/C composites. The CV test shows that the addition of carbon is 1 wt% and has the highest specific capacity of 151.27 (mAh/g). The results of the battery performance test show that the optimal addition of carbon is 1 wt%. [ABSTRACT FROM AUTHOR]
