Dendritic problems on the anodes of aqueous zinc batteries limit their development, resulting in reduced stability and lifetime. In this paper, a dual-function molecular sieve is proposed. The molecular sieve consists of 3D fibrous whiskers compounded with 2D MXene, with the zinc foil used directly as a receptor plate and assembled directly on the surface as a zinc anode by electrostatic spinning. Zinc ion transport through 3D fibrous whiskers promotes homogeneous ion flux, while Ti₃C₂T_x MXene and its abundant functional groups provide a highly reversible zinc plating/stripping process; the low lattice mismatch (∼10%) allows uniform nucleation of the transported Zn along the (0002) face. The synergistic action of the two inhibits the proliferation of dendrites on the zinc anode. Consequently, MF@Zn∥MF@Zn symmetric cells achieved stable cycling for 200 h at high current densities of 5 mA - 5 mAh cm⁻². Due to the smooth growth effect of MXene, 3D nucleation behaviour and remarkably low nucleation currents (10 mA) were observed in the Chrono Amps method (CA) method. Matched with carbon cathode, MF@Zn∥C shows the superior capacity and almost 100% retention after 2000 cycles compared to RZn. The experimental results confirm that MF@Zn 3D fibre whiskers constructed directly on zinc foil can significantly improve the performance of the cells, providing a new idea for other researchers.

水性锌电池阳极上的枝晶问题限制了其发展，导致稳定性和寿命降低。本文提出了一种双功能分子筛。该分子筛由3D纤维晶须与2D MXene复合而成，锌箔直接作为受体板，通过静电纺丝直接组装在表面作为锌阳极。锌离子通过 3D 纤维晶须的传输促进了均匀的离子通量，而 Ti₃C₂T_xMXene 及其丰富的官能团提供了高度可逆的镀锌/剥离过程；低晶格失配（~10%）允许沿（0002）面传输的 Zn 均匀成核。两者的协同作用抑制了锌阳极上枝晶的增殖。^{因此，MF@Zn∥MF@Zn对称电池在5 mA - 5 mAh cm -2}的高电流密度下实现了200小时的稳定循环。由于 MXene 的平滑生长效应，在 Chrono Amps 方法 (CA) 方法中观察到 3D 成核​​行为和非常低的成核电流 (10 mA)。与碳正极配合，与RZn相比，MF@Zn∥C显示出优异的容量，并且在2000次循环后几乎具有100%的保留率。实验结果证实，直接在锌箔上构建的MF@Zn 3D纤维晶须可以显着提高电池的性能，为其他研究人员提供了新的思路。
