Abstract

The selenium cathode for lithium–selenium batteries (Li–Se) has recently been recognized as an appealing high-energy alternative to sulfur due to its superior conductivity and chemical stability. These features open new possibilities such as alternative electrolytes that are known to be incompatible with a sulfur environment. In this work, we introduce a Li–Se battery comprising the non-flammable ionic liquid electrolyte (N-propyl-N-methyl pyrrolidinium bis(fluorosulfonylimide)) which allows the battery to operate stably from room temperature to up 70 °C. A N,S,O tri-doped mesoporous carbon is employed as a porous conductive network to host the selenium. At room temperature, the Li–Se batter..
