Abstract
- We prepare defective carbon nanosheets (DCNS) that is obtained by chemical activation of Syzygium cumini leaves and employ them as electrode materials for electrochemical supercapacitors. DCNS exhibits large specific surface area (ca. 1184.4 m2/g), electrical conductivity of ca. 1.23 × 10‐2 S/cm, moderate level of structural defects of ca. 0.72, and sufficient oxygen‐containing functional groups as well. It leads to induce huge electroactive sites, which correspond to high specific capacitance of ca. 222.26 F/g with a better durability. The low‐cost, eco‐friendly, and electroactive carbon materials could play an important role for its applications in energy‐storage devices such as batteries. [ABSTRACT FROM AUTHOR]
