In this work, we present a novel metal organic framework (MOF) derived surface modification strategy to enhance the stability and electrochemical behavior of anode-free aqueous zinc ion batteries (ZIBs). Specifically, copper ions and benzene-1,3,5-tricarboxylic acid coordinated (HKUST-1) MOFs are directly synthesized on copper (Cu) foil via a facile wet-chemical route, followed by laser carbonization to form a porous carbon-modified interface (LACI-Cu). Comprehensive structural and electrochemical analyses confirm that the fabricated LACI-Cu anodes exhibit excellent electrochemical stability, significantly improving battery performance. Symmetric cells with LACI-Cu anodes exhibit prolonged cycling stability, sustaining 1000 h at 1.0 mA cm−2 and 750 h at both 2.0 and 5.0 mA cm−2. Furthermore, full cells with LACI-Cu anodes and vanadium pentoxide (V2O5) cathodes deliver a remarkable specific capacity of 269.8 mAh g−1 at 0.1 A g−1, which is an order of magnitude higher than that of bare Cu//V2O5 cells (24.8 mAh g−1), and retain 84.5% of their initial capacity after 1400 cycles at 1.0 A g−1. These results demonstrate the potential of MOF-derived surface engineering in advancing aqueous ZIBs. The development of anode-free ZIBs represents a pivotal shift in battery architecture to overcome longstanding barriers associated with Zn metal anodes.
