Figure 8. SEM images for PCPAN (A) and SeS_x /CPAN composites (B), TEM image of SeS_x/CPAN composites (C) and EDS elemental mapping images of the SeS_x/CPAN composites, marked by a square, for carbon (D), sulfur (E) and selenium (F), (H) delithiation capacity and coulombic efficiency versus cycle number at the current density of 600 mA g^-1, (I) rate performance at various C-rates^[46], Copyright 2014, Wiley-VCH. (G)The synthetic process involves filling SeS₂ within nanochannels of CMK-3 to form CMK-3/SeS₂, followed by coating PDA sheath to obtain the CMK-3/SeS₂@PDA composite, (J) Specific capacities of CMK-3/SeS₂, CMK-3/Se, and CMK-3/S at various current densities^[48].
