Figure 11. Bifunctional separators with TMBs quantum dots for Li-S batteries. (A) Lithium-ion conductivity and long cycle stability at 2C of the cells with Mo₂N@NG/PP modified separators. (B) TEM, HRTEM images and LiPSs reduction energy profiles of MoS₂ QDs-NRGO. (C) Energy profiles of Li₂S dissociation process on the surface of VN (111) and voltage-time curves of Li-Li symmetric batteries with VN@NC separators.
