The practical applications for aqueous Zn ion batteries (ZIBs) are promising yet still impeded by the severe side reactions on metal. Here, a lysozyme protective layer (LPL) is prepared metal surface simple and facile self-adsorption strategy. LPL exhibits extremely strong adhesion to provide stable interface during long-term cycling. In addition, strategy triggered hydrophobicity-induced aggregation effect endows with gap-free compacted morphology which can reject free water effective reaction inhibition performance. More importantly, conformation transformed from α-helix β-sheet structure before formation, thus abundant functional groups exposed interact
