Uniformly coating MOF‐801 nanoparticles a pore 6.0 foil formed selective ion transport layer. uniform flux generated layer allows be transported evenly promotes deposition, leading low overpotential (17.4 mV) high cycle stability (1000 h) symmetric cell. Moreover, layer, having pores smaller than ions, blocked migrating toward anode, thereby reducing its contributing capacity retention 86% after 2000 cycles under full‐cell conditions.
