Figure 13. Functional Separator to inhibit shuttle effects for Na-S batteries. (A) Schematic diagram of the Na-S cells with bifunctional COF separators and cycle performance of Azo-TbTh-equipped batteries at 1C. (B) FESEM images of N,S-CNF/CB, UV-vis adsorption spectra of different separators and adsorption configuration for Na2S6 on a N,S-CNF surface. (C) Operating process schematic and the enhanced Na+ diffusion coefficient of RT-Na/S batteries with 2H-MoSe2/N-HCS/GO+GF. This figure is quoted with permission from
