Summary: In this research, a novel 3D cold-trap environment printing (3DCEP) technology is proposed to fabricate the MXene and Zn-P (3DCEP-MXene/Zn-P) anode with highly ordered arrangement. The 3DCEP-MXene/Zn-P anode demonstrates improved cycling lifespan and coulombic efficiency due to the unique inhibition mechanism and physical confinement effects within the anode. Furthermore, when paired with MXene and Co doped MnHCF cathode via 3DCEP, the full battery shows high cyclic durability with a capacity retention of 95.7% after 1600 cycles.

Summary: Aqueous rechargeable Zn-ion batteries (ARZIBs) have gained attention for their safety, high energy density, and environmental friendliness. However, dendrite formation and corrosive reactions on the Zn anode surface have posed challenges. In this study, Ga3+-doped NaV2(PO4)(3) with Na superionic conductor (NASICON) structure was used as an artificial layer to stabilize the Zn anode. The optimal NVP-Ga(0.5) layer effectively homogenized ion flux and promoted uniform deposition of zinc, inhibiting dendrite growth and parasitic reactions. The resulting batteries showed stable operation and high discharge capacity.

Summary: The addition of additives such as hexanehexol (Hex) can enhance the reversibility of Zn-metal aqueous batteries by regulating the solvation shell and electrode interface. Experimental results show that Hex, with 6 hydroxyls, is the most effective additive as it forms more hydrogen bonds with active H2O molecules and achieves stronger adsorption energy with Zn metal. This hydroxyl chemistry strategy can be applied to screening other electrolyte additives, indicating its practical universality.
