In this contribution we are reporting the cycling performance of GO-S & rGO-S composite cathode with solid electrolyte lithium sulphide and phosphorous pentasulfide (Li2S/P2S5) for solid state lithium sulphur batteries. The composite cathode was fabricated via different composition of S, GO and rGO with acetylene dark (AB) and Li2S/P2S5 by ball-milling. Electrochemical performance has been tested by galvanostatic charge-discharge at 0.1C c-rate showing initial charge capacity approx1800 mAh/g and constant capacity upto 390 mAh/g over no of cycles. Our results indicate a significant improvement in rate and cycling performance of Li2S/P2S5 solid electrolyte.
