Abstract
High activation potential and poor electronic/ionic conductivity greatly hinder the practical application of Li 2 S as the cathode material in lithium-ion sulfur batteries. Introducing electrolyte additives is one of the most promising strategies to address these challenges. Appropriate electrolyte additives not only lower the activation potential of Li 2 S but also promote the rate capability and cycling performance. In this Perspective, recent research progress on using electrolyte additives to reduce the activation potential of Li 2 S is reviewed, and future possibilities are proposed.
