Abstract

Carbon material derived from biomass is used to modify the sulfur cathode. The modified sulfur cathode composite (ACS) together with PEDOT: PSS-CNT interlayer is used to visualize high performance Li-S cells. The Li-S cells with the interlayer inserted between the separator and ACS cathode shows remarkably improved electrochemical activity with an initial discharge capacity of 950 mA h g^-1 at 0.2 C. The improved performance for the interlayer assisted Li-S cells is due to the conductivity of the interlayer, also it can hold back the migrating polysulfides with in the cathode region and hindering the polysulfide shuttling phenomenon.
