Dual carbon batteries (DCB) are gaining traction in energy storage research due to their cost-effectiveness, better safety, eco-friendliness, and rapid charging capability. Despite these merits, carbon-based electrode systems face many challenges, particularly in their relatively lower energy density. Researchers are addressing this by exploring innovative strategies, with a focus on electrolyte additives. One noteworthy additive is ethylene sulfite (ES), recognized for its protective effect on electrodes. This study compares two LiTFSI-based electrolytes, one of which is enhanced with ES, to determine their potential in improving DCB capabilities. The LiTFSI-ES electrolyte demonstrates a higher conductivity (7.29×10-3 S cm-1) and a broader potential window (5.554 V) compared to LiTFSI alone. Cyclic voltammetry (CV) and dQ/dV analysis confirm the intercalation of TFSI-anions in the graphite electrode, indicating DCB behavior. This research contributes valuable insights into enhancing DCB performance through the incorporation of ES and sheds light on the electrochemical behavior of the LiTFSI-ES electrolyte.
