Abstract The development of lithium–sulfur batteries is impeded by their suboptimal electrochemical performance and significant self‐discharge under practical conditions, especially at high sulfur‐to‐host ratios low electrolyte‐to‐sulfur ratios. Under these improving necessitates accelerating the polysulfides conversion, while reducing entails inhibiting same conversion (disproportionation reaction, a key contributor to self‐discharge). Herein, address this challenging contradiction, an imprisoning strategy designed that utilizes programmable solid electrolyte interphase (SEI) layers formed only on outer surface TiO 2−x coated hollow carbon spheres (TiO @C). @C chosen primarily because it supports regulated SEI growth upon simple voltage control, leveraging different formation potential C, its conductivity catalytic property ensure sulfur reaction kinetics. This functions effectively even conditions. exposed internal provides abundant effective sites (as dense barrier) prevents from migrating out spheres, performance. These soluble polysulfides, being confined within easily reach saturation concentrations during storage, disproportionation reaction. Consequently, wrapped @C/sulfur cathodes exhibit both self‐discharge. work new attempt achieve above simultaneous optimization without compromise.
