“…As expected, it is highly desirable to develop UIO-66 with improved conductivity and enhanced mechanical properties. The use of carbon-based materials [e.g., nitrogen-doped graphene, MXene, and reduced graphene oxide (rG)] as protective layers has been proven to be an effective way to enhance the cycling performance. This is mainly due to the abundant deposition sites of Zn 2+ , reduced local current density, uniform electric field distribution, and strong mechanical properties of carbon-based materials during the cycles …”

Rechargeable aqueous Zn-ion batteries with a Zn anode hold great promise as promising candidates for advanced energy storage systems. The construction of protective layer coatings on Zn anode is an effective way to suppress the growth of Zn dendrites and water-induced side reactions. Herein, we reported a series of UIO-66 materials with different concentrations of reduced graphene oxide (rG) coated onto the surface of Zn foil (Zn@UIO-66/rG x ; x = 0.05, 0.1, and 0.2). Benefiting from the synergistic effect of UIO-66 and rG, symmetric cells with Zn@UIO-66/rG x (x = 0.1) electrodes exhibit excellent reversibility (e.g., long cycling life over 1100 h at 1 mA cm −2 /1 mAh cm −2 ) and superior rate capability (e.g., over 1100 and 400 h at 5 mA cm −2 /2.5 mAh cm −2 and 10 mA cm −2 /5 mAh cm −2 , respectively). When the Zn@UIO-66/rG 0.1 anode was paired with the NaV 3 O 8 •1.5H 2 O (NVO) cathode, the Zn@UIO-66/rG 0.1 ||NVO cell also delivered a high reversible capacity of 189.9 mAh g −1 with an initial capacity retention of 61.3% after 500 cycles at 1 A g −1 , compared to the bare Zn||NVO cell with only 92 cycles.
