A shuttle effect free lithium sulfur battery based on a hybrid electrolyte†
Abstract
A room temperature hybrid electrolyte based lithium–sulfur cell was successfully cycled with an excellent coulombic efficiency of 100%. The initial discharge specific capacities of up to 1528 mA h g−1, 1386 mA h g−1 and 1341 mA h g−1, respectively, at C/20, C/5 and C/2 rates were realized and remained at 720 mA h g−1 after 40 cycles at the C/5 rate.
