Abstract It is still challengeable to inhibit the uncontrollable growth of lithium dendrites and large volume expansion during cycling for high‐energy metal batteries (LMBs). To simultaneously address such issues, herein, first time, a novel dual‐protective artificial solid electrolyte interface (SEI) combining “soft” covalent–organic framework (COF) spheres grown on “rigid” MXene nanosheets (MXene/COF) via facile mild method presented. The can provide abundant lithium‐ion diffusion channels promote rapid uniform deposition. unique rigid‐soft MXene/COF composite has outstanding mechanical flexibility mitigate SEI cracking, limit prevent dendrite puncture cycling. As result, Li||Li symmetrical cell, Li||LFP full cell Li||NCM811 with dual protective interlayers demonstrate much better electrochemical performances, compared those without interfaces. performance enhancement mechanism revealed by X‐ray photoelectron spectroscopy depth profiling in situ optical microscopy be attributed form lithiophilic layer, fast Li + transport, deposition caused interface. This work provides new insight into rational design, fabrication, mechanisms dual‐protective, soft‐rigid high‐performance LMBs.
