Lithium-sulfur batteries are promising high-energy-density devices for next-generation energy storage systems. One of the most challenging issues impeding their practical application is how to develop cost-effective thick sulfur cathode with fast kinetics. Carbon aerogels (CAs) show great potential as host for lithium-sulfur batteries, while the preparation of CAs usually requires special time-consuming...
1,1,2,2-Tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether (TTE) was selected as a co-solvent of ionic liquid for fabricating the functional electrolyte of Li-S batteries. The basic properties of the electrolyte and electrochemical performances of the cell with alterative TTE contents were intensively investigated. It is found that the fluorinated ether helps to promote ion conduction in the electrolyte,...
