Figure 5. Comparative electrochemical performance of cells with the pristine and functionalized separators. (A) Typical galvanostatic charge-discharge curves of the cell with the functionalized separator (inset: CV curves at 0.1 mV s^-1). The primary comparative cycling stability at 0.1 C; (B) and the rate capabilities (C); (D) Performance comparison of separator modification strategy proposed in this work to other previous strategies; (E) Long-term cycling of the cell with functionalized separator at 0.5 C (inset: photographs of a coin cell lighting up a light-emitting diodes). (E was photographed by the author, without any copyright concerns). CV: Cyclic voltammetry; N-AC: nitrogen-doped activated carbon; CE: Coulombic efficiency.
