Hollow carbon materials have been extensively investigated as sulfur hosts for lithium‐sulfur batteries. Herein, we report a designed synthesis of nitrogen‐doped mesoporous hollow carbon spheres with tunable void spaces through an ethylenediamine‐assisted cooperative self‐assembly strategy between 3‐aminophenol/formaldehyde resin and silica. Nitrogen‐doped hollow mesoporous carbon spheres (NHMCS) with an optimised inside/outside radius ratio of 0.52 have induced improved electrochemical performances compared to other NHMCS, demonstrating a fine material design strategy for electrochemical energy storage systems with improved performance.
