Electrolyte Additives for High-Energy-Density Lithium-Sulfur Batteries: From Fundamental Challenges to Rational Design Strategies.
Lithium-sulfur (Li-S) batteries are regarded as one of the next-generation batteries owing to high theoretical energy density and low cost. However, their practical application is severely hindered by lithium polysulfides (LiPSs) shuttle, which not only leads to sluggish sulfur redox kinetics at the cathode but also in...
