A successful approach to modifying the intrinsic properties of
pure carbon is by doping with heteroatoms, such as N, B, S, and
P.30 Doping carbons by N has been by far the most widely
investigated and yields a thriving class of N-doped carbon
materials with various applications, including Li-ion batteries.
30−34 In Li−S batteries, N-doped carbons have been
reported to exhibit improved conductivity and enhance the
activity of S.35,36 B, electron-deficient counterpart to N, is
another prospective dopant.37−39 On one hand, B-doped
carbon has higher conductivity than plain carbon, much like
that of N-doped carbon. On the other hand, in contrast to Ndoped
carbon, B dopant in the carbon framework is positively
polarized, leading to chemisorption with negatively charged
species.37 Thus, B-doped carbons are expected to attract
polysulfide anions, thereby alleviating the shuttle effect.
Herein, we gain an insight into the role of B dopant on S/C
cathode by using B-doped porous carbon (BPC) as the host
material for S. Our study shows that because of the synergy
between B, C, and S, doping with B remarkably improves the
conductivity of the crude porous carbon and alters its surface
properties to effectively trap the polysulfide anions. Therefore,
S/BPC cathode shows high capacity, stable cyclability, and
excellent rate capability.
