Anovel lithiated Si–S battery exploiting an optimized solid-like electrolyte is presented. This electrolyte is fabricated by integrating ether-based liquid electrolyte with SiO₂ hollow nanosphere layer to suppress the shuttle effect and fluoroethylene carbonate additive to optimize the anodic solid electrolyte interface. The prepared lithiated Si–S batteries exhibit enhanced cycle life, low flammability, and strong recovery ability against short-circuit.
