How should one design porous carbon materials for advanced Li-S batteries cathodes? What electrolytes are extensively studied for high-safety Li-S batteries? In a paper published in Nano<\/i>, a group of researchers from Qingdao, China have reviewed the recent progress in sulfur\/carbon cathode materials and high safety electrolytes towards advanced Li-S batteries. Some potential issues and possible developmental directions are also discussed.<\/p>\n

\n <\/section>\n

Lithium-sulfur (Li-S) battery is one of the most promising secondary batteries for its high energy density, high natural abundance and environment-friendly nature of sulfur. However, the commercial app<\/a>lication of Li-S battery faces some technical obstacles, such as low cycling stability resulted from the shuttle effect of polysulfides, low electrical conductivity of sulfur, and volume expansion during charge\/discharge process. Furthermore, due to the flammability of organic solvents in liquid electrolytes, the continuous formation of lithium dendrites and the low ignition temperature of carbon-sulfur mixtures, the safety of Li-S batteries has become another critical issue to be solved.<\/p>\n

In recent years, many different strategies have been put forward to improve the electrochemical performance and safety of Li-S batteries, containing the development of carbon\/sulfur composite cathodes, design of flame retardant electrolytes and protection of negative electrodes. In this review, the challenges and trends of Li-S batteries are first discussed. The recent progress of sulfur\/carbon composite cathode materials for Li-S battery is then introduced in detail. Then the evaluation methods and latest development of high-safety electrolytes towards advanced Li-S batteries are summarized. Finally, the development trends of Li-S battery are forecasted. Although some issues in Li-S batteries are still unknown or contradictory, its mysterious veil will be gradually revealed with further in-depth research.
