Herein, we propose a synergistic modification design scheme to adjust the oxygen activity from surface to bulk. The LiBO<sub>2</sub> coating inhibits the reactivity of surface lattice oxygen ions. Meanwhile, Zr doping in the bulk phase forms strong Zr–O covalent bonds that stabilize the bulk lattice oxygen structure. The synergistic effect of these modifications prevents the release of oxygen, thus avoiding the degradation of the cathode/SE interface. Additionally, the regulation of surface-to-bulk oxygen activity establishes a highly stable interface, thereby enhancing the lithium ion diffusion kinetics and mechanical stability of the cathode. Consequently, cathodes modified with this synergistic strategy exhibit outstanding performance in sulfide-based ASSLBs, including an ultra-long cycle life of 100,000 cycles, ultra-high rate capability at 45C, and 85% high active material content in the composite cathode.
