Lithium-sulfur battery, one of the most promising rechargeable electrochemical systems, has suffered several technical obstacles, such as rapid capacity fading and safety concerns. The former mainly result from the “shuttle” mechanism due to the dissolution of the reaction intermediates lithium polysulfides; the latter can be attributed to the highly flammable electrolyte. To overcome these problems,...
Rechargeable Li–S batteries have suffered several technical obstacles, such as rapid capacity fading and low coulombic efficiency. To overcome these problems, we design new electrolytes containing N-methoxyethyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl)-imide (Pyr1,2O1TFSI) and tri(ethylene glycol)dimethyl ether (TEGDME) in mass ratio of 7:3. Moreover, Lithium difluoro(oxalate)borate (LiODFB)...
