We reported a spherulite-packed polymer electrolyte prepared by modulating the phase separation kinetics with TEGDME and the in situ polymerization of AMPSLi. This structure established a synergistic physical-electrostatic barrier against polysulfides. Consequently, lithium-sulfur batteries retain a capacity of 705 mAh g-1 after 300 cycles at 1C, demonstrating enhanced long-term stability.
