Electro active organic compounds represent one of the most capable electrode materials for the next generation green and sustainable rechargeable lithium ion batteries. In this context, we highlight the synthesis of an organic electrode material of azo derivative; diazoaminobenzene (DAAB) by diazotization method followed by lithiation using conventional technique. The electrochemical performances of the electro‐active species are examined by Cyclic Voltammetry, Galvanostatic Cycling with Potential Limitation and Potentio‐electrochemical Impedance Spectroscopy in an aqueous saturated Li 2 SO 4 electrolyte. DAAB has shown considerable progress in terms of cyclic performance, better rate capability and high reversible capacity. The electroactivity of active species are enhanced by the addition of carboxy‐functionalized carbon nanotubes (CNTs‐COOH) as an additive. The half‐cell of lithiated diazoaminobenzene/CNTs‐COOH (dLiDAAB) vs. SCE delivers a capacity of 173.7 mA h g −1 up to 10 cycles at 0.08 mA. The full cell configuration dLiDAAB | aq. Saturated Li 2 SO 4 | 2‐[1H‐indol‐2‐yl (1H‐indol‐3‐yl) methyl] phenol (b‐IMP) delivered a discharge capacity of 81.99 mA h g −1 in the potential window of −0.2 V to 1.2 V. The battery performance of the cell has been increased significantly by the influence of CNTs‐COOH group with 96.95% columbic efficiency. This agreeable result markably suits this material as an anode in aqueous rechargeable lithium batteries for future needs of energy technology.
