A carbon nanotube/nanofiber (CNT/CNF) composite is applied as a cathode substrate to develop a high-loading polysulfide cathode (8.64 mg cm, 68 wt% sulfur). The high-loading CNT/CNF-polysulfide cathode demonstrates high energy densities (11.4-15.7 mW h cm) and long-term cyclability (200 cycles) with low electrolyte-to-sulfur (E/S) ratios of 4-7 μL mg.
一种碳纳米管/纳米纤维（CNT/CNF）复合材料被用作阴极基底，以开发一种高负载量的多硫化物阴极（8.64毫克/平方厘米，68重量%硫）。这种高负载量的CNT/CNF-多硫化物阴极在低电解液与硫（E/S）比为4 - 7微升/毫克的情况下，展现出高能量密度（11.4 - 15.7毫瓦时/平方厘米）和长期循环稳定性（200次循环）。
