Dictating High‐Capacity Lithium–Sulfur Batteries through Redox‐Mediated Lithium Sulfide Growth (Small Methods 6/2020)

Regulating the redox reactions is critical for rechargeable batteries based on conversion chemistries. In article number 1900344, Jia-Qi Huang and co-workers introduce cobaltocene as a persistent extrinsic redox mediator to dictate an alternative redox pathway, which not only benefits high-rate or electrolyte-lean lithium–sulfur batteries but also paves a way toward the rational design of novel redox mediators in dissolution-precipitation energy chemistries.
