AB  - Aluminum-sulfur (Al-S) batteries are promising energy storage devices due to 
      their high theoretical capacity, low cost, and high safety. However, the high 
      viscosity and inferior ion transport of conventionally used ionic liquid 
      electrolytes (ILEs) limit the kinetics of Al-S batteries, especially at sub-zero 
      temperatures. Herein, locally concentrated ionic liquid electrolytes (LCILE) 
      formed via diluting the ILEs with non-solvating 1,2-difluorobenzene (dFBn) 
      co-solvent are proposed for wide-temperature-range Al-S batteries. The addition 
      of dFBn effectively promotes the fluidity and ionic conductivity without 
      affecting the AlCl(4) (-) /Al(2) Cl(7) (-) equilibrium, which preserves the 
      reversible stripping/plating of aluminum and further promotes the overall 
      kinetics of Al-S batteries. As a result, Al-S cells employing the LCILE exhibit 
      higher specific capacity, better cyclability, and lower polarization with respect 
      to the neat ILE in a wide temperature range from -20 to 40  degrees C. For instance, Al-S 
      batteries employing the LCILE sustain a remarkable capacity of 507 mAh g(-1) 
      after 300 cycles at 20  degrees C, while only 229 mAh g(-1) is delivered with the 
      dFBn-free electrolyte under the same condition. This work demonstrates the 
      favorable use of LCILEs for wide-temperature Al-S batteries.
