英文摘要Aimed at tackling the shuttle effect in lithium-sulfur (Li-S) batteries, a Li1.5Al0.5Ge1.5(PO4)(3)(LAGP) ceramic is adopted to block the migration of polysulfides. However, the LAGP-based Li-S battery with liquid electrolyte wetting the interfaces still suffers from rapid capacity decay, as polysulfides tend to dissolve into liquid electrolyte and get firmly adsorbed by LAGP. In this work, a dual confinement effect for polysulfides is put forward, enabled by the LAGP ceramic and solvent-in-salt (SIS), wherein the SIS can greatly suppress the dissolution of polysulfides. Owing to the synergistic effect of SIS and LAGP, the semi-solid-state Li-S batteries show superior capacity retention and long cycling life. In particular, at a current density of 0.2 C, the Li-S battery with SIS-modified LAGP ceramic electrolyte delivers a high initial reversible capacity of 1251.7 mAh g(-1)and long cycle life of over 250 cycles with a decay rate of only 0.07 % per cycle.
