The inhomogeneous interfacial electrochemical reaction process of the metallic zinc anode in aqueous zinc-ion batteries will lead to serious problems dendrite growth and side reactions, resulting poor cycle stability. In this study, through a structure - interface collaborative regulation strategy, biomass-derived porous carbon/zinc composite electrode (LiPBC@Zn) with lithium-activated has been developed, which significantly improves stability suppression ability zinc-based batteries. Biomass-derived carbon (PBC) three-dimensional interconnected hierarchical pore network structure, specific surface area 242.39 m 2 g −1 , an average diameter 2.43 nm. prelithiation treatment induces formation Li O layer, can increase proportion lithium atoms from 3.53% 19.11%, regulate nucleation behavior charge redistribution. full cell test shows that V 5 -LiPBC@Zn no capacity decay after 1000 cycles at 1 A still retains 61.3% its 2000 cycles. This study guides uniform deposition dual mechanism “lithium-induced carbon-confined,” effectively suppressing growth, provides theoretical basis technical path for engineering design high-safety energy-storage devices.
