“…Compared to SnS 2 @TiC/C, the signal of P and O elements has been found in P‐SnS 2 @TiC/C, indicating the successful introduction of P species. In the P 2p spectra of P‐SnS 2 @TiC/C (Figure 3d), there is a characteristic peak at 134.6 eV corresponding to PO bond and another remarkable peak at 139.5 eV belonging to tin pyrophosphate, [ 36 ] while the peak for PSn bond at around 130.0–132.0 eV is not detected, demonstrating that P species are indeed presented in the form of PO 4 3− in the P‐SnS 2 @TiC/C arrays. The high‐resolution S 2p spectra for P‐SnS 2 @TiC/C and SnS 2 @TiC/C are illustrated in Figure 3e.…”

“…It is proven that the doping or intercalation of ions group can modulate the band structure to improve the electric conductivity and offer more active sites for metal sulfides, thus leading to the enhancement of electrochemical performance. [36,37] Recently, phosphate ion (PO 4 3− ) doping has aroused wide concern due to its large ion radius of ≈2 Å and high electronegativity. On the one hand, the phosphate ion with large ion radius could be introduced into the interlayer as a doping site to enlarge the interlayer spacing of sulfides, which can improve the transfer of Na + .…”

“…Recently there has been an increase in research activities focusing on the development of nanostructured materials [1] as anodes to enhance the capacity, energy density and specific power of rechargeable Lithium-ion Batteries (LIBs) [2][3][4][5][6][7]. In the early development of the lithium battery chemistry, lithium metal foil was widely used as the anode material because of several electrochemical attributes; light weight, high voltage, and high energy density.…”

“…In recent literature, Yu et al [83][84][85][86] have achieved the in-site addition of transition metallic (Ti and Cu) and nonmetallic elements (P and B) into SnO x /CNF composites for the enhancement of cycling stability and rate performance via the electrospinning technique and subsequent thermal treatments. It was demonstrated that the doped SnO x nanoparticles were all ultrafine and uniformly dispersed in the conductive CNF matrix, and the doping content should be kept to an optimal value.…”
