摘要 | Lithium-sulfur batteries (LSBs) are considered the most likely replacement for conventional lithium-ion batteries in next-generation high-energy output solutions based on their high specific capacity (1675 mAh g(-1)) and high-energy density (2600 Wh kg(-1)). But, there are some problems that need to be solved urgently. In this work, an environmentally friendly, green, and low-cost ZIF-67-derived cobalt-based sulfate material (CoSO4) combined with carbon nanotubes was proposed as a sulfur host material. Experiments show that the addition of CoSO4 can significantly enhance the transformation of polysulfide and suppress the shuttle effect. The best performance is the CNT-CoSO4-2/S, which has an initial capacity of 1356.9 mAh g(-1) at 0.1 C current density. Furthermore, long-term cycle test was carried out at a current density of 0.2 C; the coulombic efficiency was above 98.63% after 200 cycles. This work demonstrates the potential of cobalt-based sulfates as cathode materials for lithium-sulfur batteries. |
