摘要：

On paper: A lithium/dissolved polysulfide cell is developed utilizing a self-weaving, free-standing multiwalled carbon nanotube (MWCNT) "paper" as a host for the dissolved polysulfide active material and the reaction products. Exceptionally high capacities of 1600 mAh g-1 initially and 1411 mAh g-1 after 50 cycles (based on the mass of sulfur) are obtained at a rate of C/10. Copyright © 2013 WILEY-VCH Verlag GmbH & Co.
