Abstract

Aluminum-sulfur (Al−S) chemistry is attractive for the development of next-generation rechargeable battery systems. However, only a few reversible Al−S cells have been reported until now. This paper demonstrates that the use of an AlCl₃/urea electrolyte in Al−S cells is a promising approach to improve the cycle life and reach a high discharge voltage plateau of ∼1.6–2.0 V. In contrast to the instability of sulfur in the conventional AlCl₃/EMIC electrolyte, sulfur is chemically stable in the AlCl₃/urea electrolyte, which allows better cell cycling stability. The Al−S cell delivers an initial capacity of ∼700 mAh g_s ⁻¹ and maintains a capacity of up to ∼500 mAh g_s ⁻¹ after 100 cycles.
