Özet

Aqueous zinc-ion batteries (ZIBs) have attracted growing interest as safe, sustainable, and cost-effective energy storage systems; however, the inherent instability of zinc (Zn) metal anodes remains a major barrier to their practical application. In this study, a laser-assisted carbonization technique was used to fabricate a metal-organic framework (MOF-5)-derived carbon layer on a Zn anode. MOF-5 was directly synthesized on the Zn surface via wet chemistry and then converted into a porous carbon layer (c-MOF-5) via laser treatment under ambient conditions. Structural and morphological characterizations confirmed the successful transformation of MOF-5 into a porous, ion-permeable carbon interface. Electrochemical results demonstrate that the c-MOF-5 interface effectively regulates Zn2+ flux, reduces side reactions, and accelerates charge-transfer kinetics. As a result, the c-MOF-5/Zn anode exhibits highly stable Zn plating/stripping behavior for over 1000 h at 10 mA cm−2 (10 mAh cm−2) in symmetric cells. When paired with a V2O5 cathode, the c-MOF-5/Zn//V2O5 full cell delivers a high discharge capacity of 278.2 mAh g−1 at 1.0 A g−1 and retains 189.7 mAh g−1 after 300 cycles, significantly outperforming bare Zn-based counterparts. This study demonstrates that laser-carbonized MOF-derived interfaces provide a scalable, effective route to stabilize Zn anodes, advancing the development of high-performance aqueous ZIBs.
