The Front Cover shows how the cobalt oxalates faced on the conductive carbon can act as an electrocatalyst to facilitate the redox reaction of lithium polysulfide at the cathode interface in lithium–sulfur batteries. The lithium polysulfides, produced in the middle of an electrochemical reaction, can be adsorbed on the interfacial boundary area contacted with carbons and cobalt oxalates. Then, the adsorbed lithium polysulfides convert to thiosulfate and polythionate. More information can be found in the Full Paper by J.‐W. Kim et al.
