a) Rate performance of various modified separators at different specific currents; b) galvanostatic charge–discharge profiles of LSBs based on Ni‐HAB@CNT modified separators under different C‐rates; c) polarization potentials of various modified separators at different rates; d) cycling performance at 0.2 C; e) long‐term cycling stability at 1 C; f) cycle performance of Ni‐HAB@CNT separator with high sulfur loading at 0.2 C; g) electrochemical performances of the pouch cells with sulfur loading of 2.5 mg cm⁻² and E/S ratio of 6 µL mg⁻¹ at 0.1 C; the inset in (g) shows the digital photo of the fresh pouch cell and corresponding initial voltage; h) charge–discharge profiles of the pouch cell. Inset shows the digital photograph of the number of 67 LED lamps powered by Ni‐HAB@CNT pouch cell.
