摘要
虽然锌金属阳极在水锌离子电池中具有一些固有的优点,但其不良的枝晶结构阻碍了其实际应用。本文探索了一种通过MXene-mPPy层制备无枝晶锌金属阳极的富电荷策略。在Ti3C2Tx-MXene两侧由介孔PPy组成的mxene - mxene层表现出优异的电荷富集能力(149 F g−1,5 mV s−1),这不仅有利于电荷水平的积累,而且有利于电场和离子通量的分散均匀化,可作为Zn阳极上的人工界面。因此,无枝晶锌阳极具有长达2500小时的超长循环寿命和卓越的倍率能力,进一步应用于水锌离子电池的阳极,在10 a g−1下具有超过3000次循环的长期跨度。
Charge-Enriched Strategy Based on MXene-Based Polypyrrole Layers Toward Dendrite-Free Zinc Metal Anodes
Although zinc metal anodes have some intrinsic advantages for aqueous zinc ion batteries, the notorious dendrites hamper its practical applications. Herein, a charge-enriched strategy through MXene-based polypyrrole (MXene-mPPy) layers is explored toward dendrite-free Zn metal anode. The MXene-mPPy layers composed of mesoporous PPy on both sides of Ti3C2Tx-MXene exhibit an exceptional charge enrichment ability (149 F g−1, 5 mV s−1), which is beneficial not onlying terms of accumulating the charge levels, but also to homogenize the dispersions of electric field and ion flux as used as an artificial interface on a Zn anode. Thus, a dendrite-free Zn anode with an ultralong cycling lifespan up to 2500 h and superior rate capability is achieved, which is further applied as an anode for aqueous zinc ion batteries with a long-term span over 3000 cycles at 10 A g−1.
