Abstract:
Secondary lithium-sulfur batteries have attracted extensive attention due to their high energy density, low cost and environment friendly. However, the "shuttle effect" of polysulfides dissolved in liquid electrolytes leads to a decrease of the cell Coulomb efficiency (CE). Therefore, researchers have used solid electrolytes instead of traditional liquid electrolytes and separators to suppress the "shuttle effect" of polysulfides and the growth of lithium dendrites. The progress in electrolytes for solid-state lithium-sulfur batteries including solid-state polymer, inorganic, and composite electrolytes to solve the issues is summarized.
