“…Pyridine nitrogen can promote the coordination of metal ions, and thus, is more favorable for the removal of metal ions [42]. , and S(-II) (160.6 eV) [35,43]. This confirms that the sulfur was successfully doped into the biochar carbon skeleton structure after modification.…”

“…Figure S3 (C2) is the S 2p spectrum of SBC-600 and TSBC-600. Compared with SBC-600, the sulfur content of TSBC-600 is significantly increased, and the sulfur exists in five main forms, i.e., C=S (163.9 eV), C-S (165.1 eV), S(=O)2 (168.3 eV), Sul S (sulfide sulfur, 161.8 eV), and S(-II) (160.6 eV) [35,43]. This confirms that the sulfur was successfully doped into the biochar carbon skeleton structure after modification.…”

“…In Li-S batteries, the -SO 3 H group can provide powerful chemical anchoring for lithium polysulfides. Wei et al [81] selected the PANI and SPANI to coated on the surface of bambooderived porous carbon/sulfur composites, respectively. The -SO 3 H group of SPANI improved the transmission rate of electrons and lithium ions and optimized the reaction kinetics, which significantly improved cycling stability and superior rate performance of the electrode.…”

“…Therefore, it would be economically beneficial to utilize biochar particles to develop innovative carbon nanofibrous felt for high-value applications. Because of biochar’s carbon-rich feature, it is particularly promising for use in energy storage and conversion applications [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. However, most of the reported biochar particles were in powder form rather than being incorporated in the matrix, which limits its application as a binder-free electrode.…”
