The thermal safety issues of currently available Ni-rich cathode-based power supplies brought in the development all-solid-state batteries, yet cascade reactions materials and chemo-mechanical degradation between cathode solid electrolyte diminished cycle life. Here, by introducing a new heteroatom chemical competing diffusion strategy, we successfully stabilize contact face with an electrolyte. Combining extensive explorations theoretical calculation multiscale in/ex situ characterization, elucidate atomic-level upon topological lithiation layered materials. heteroatoms higher binding energy to coordinated oxygen served as "oxygen anchor" bulk alleviated excessive oxidation through charge compensation, thus easing aggression evolved oxygen. Comparably, others were enriched surface formed ionic "diffusion regulator" residual lithium, special transfer regulation mechanism piezoelectric layer validly improved interface compatibility weakened space-charge solid-state batteries. This helped designed sulfide battery exhibit excellent cyclability under 4.5 V (97.3% after 120 cycles). Our findings unlocked structure–function relationship polarization field generated material electrode.
