Figure 7. (A) PhSLi (left) and Li₂S₆ (right) on TiS₂ with differential charge contour surfaces in three dimensions. Carbon, hydrogen, lithium, sulfur, and titanium are depicted in gray, white, purple, yellow, and blue. The electronic attachment and detachment densities are represented by surfaces colored blue and green, respectively. Reproduced with permission from Ref.^[56] (Copyright 2020, Wiley-VCH GmbH). (B) Schematic diagram of improving battery performance with MSGC substrates. Reproduced with permission from Ref.^[57] (Copyright 2021, Wiley-VCH GmbH). (C) VS₄ Raman spectra in different charged states (pristine, 3.0 V live and 3.1 V charged). (D) The specific capacity of CNTs/VS₄/DPDS is compared with the total specific capacity of CNTs/DPDS and CNTs/VS₄. Reproduced with permission from Ref.^[58] (Copyright 2021, Wiley-VCH GmbH).
