▎ 摘　　要

A sulphur/boron-doped reduced graphene oxide (S/B-rGO) composite was prepared using a facile hydrothermal method. The two-dimensional stacked nanosheet structure of the S/B-rGO composite provides an effective electron-conduction path and traps soluble polysulphide intermediates via the introduction of boron doping. The electrochemical performance delivers a relatively high reversible discharge capacity of 521.9 mAh g(-1) after 100 cycles at 0.1 C with a boron-doped reduced graphene oxide composite lithium/sulphur battery.
