Recently, the increment of energy consumption of high technological advancement and the requirement of environmentally-friendly energy sources make a necessity of new conceptual energy source. Notably, among various approaches for promising energy sources, electrochemical energy storage system seems appealing for its high energy conversion efficiency and low product of pollutant. Lithium-sulfur secondary battery is one of the most promising electrochemical redox couple system for storage chemical energy directly to electrical energy. Although a pleny of research has been conducted in this field, several issues still remain, including its low electrical conductivity, irreversible loss of polysulfides and volume expansion during battery cycling. In this presentaion, I would like to talk about varous carbonaceous materials for applying lithium-sulfur battery to solving problems. |
