摘要: Abstract In this paper, metal-organic framework-74-Ni/carbon nanotube (MOF-74-Ni/CNT) composite was synthesized via one-pot in situ hydrothermal reaction. The MOF-74-Ni/CNT characterized and the electrochemical performance investigated. sulfur cathode prepared by impregnation method delivers a high initial discharge capacity, good rate capability low capacity decay of 0.087% per cycle over 400 cycles at 2 C. significant attributed to combination affinity MOF-74-Ni polysulfide anions excellent electronic conductivity carbon nanotube. These results suggest design polar MOF materials with conductive CNT is an effective strategy construct promising host for Li-S batteries.
