high performance room temperature sodium sulfur battery enabled by electrocatalytic sodium polysulfides Full Conversion
Energy and Environmental Science, 2020Co-Authors: Nana Wang, Yunxiao Wang, Zhiwei Fang, Xiao Zhang, Zhongfei Xu, Yu Ding, Xun Xu, Yi Du, Guihua YuAbstract:Room-temperature sodium–sulfur (RT-Na–S) batteries are highly desirable for grid-scale stationary energy storage due to their low cost; however, short cycling stability caused by the incomplete Conversion of sodium polysulfides is a major issue for their application. Herein, we introduce an effective sulfiphilic host, gold nanodots decorated on hierarchical N-doped carbon microspheres (CN/Au/S), to achieve completely reversible Conversion reactions in the S cathode by electrocatalyzing the low-kinetics Conversion of Na2S4 into NaS2 (discharge process) or S (charge process). Besides, gold nanodots and N-doped carbon can increase the conductivity of the S cathode and provide strong polar–polar adsorption of sodium polysulfides to alleviate the shuttling effects. When serving as the cathode, the CN/Au/S composite can realize enhanced sulfur utilization, excellent cycling stability, and outstanding rate capability. This work deepens our understanding of the catalytic effect of gold atoms on sulfur molecules, opening a new avenue for cathode design and development of advanced RT-Na–S batteries.
