The crystallographic orientation of Zn metal is related to its deposition pattern, plating/stripping reversibility, the HER and corrosion. Herein, theoretical calculations show that the (002) crystal plane of Zn metal not only is beneficial for the reversibility of Zn plating/stripping and inhibition of dendrites, but also inhibits the HER and alkaline corrosion. A meter-scale graphene-modified copper collector (Cu@G) was continuously prepared using shear-flow induction. The Cu@G collector selectively locks the lattice orientation of Zn deposits, enabling the closest packing crystallography of the (002) textured Zn metal anode. The SEM electron backscattered diffraction (EBSD) and XRD results show that Zn was deposited on the surface of the Cu@G collector with an ultra-high and uniform (002) orientation. Electrochemical test results show that the Cu@G collector exhibits excellent plating/stripping reversibility and a superior cumulative plating capacity (>6900 cycles at 40 mA cm⁻² with 2 mA h cm⁻², an ACE of up to 99.977%, and a CPC of up to 13 860 mA h cm⁻²). Zn²⁺ hybrid supercapacitors (ZHSs) and zinc ion batteries (ZIBs) also show excellent performance (ZHSs can be recycled >48 000 times with a capacity retention ratio of 94.6% and an ACE close to 100%; the capacity retention ratio of a Zn//PANI full cell is 80.43% after 130 cycles with a CE of 100% at N/P = 2.35). We also demonstrate an anode-free design (i.e., zero-excess Zn) with a modified Cu@G collector, and this Zn-manganese (MnO₂) double-plated cell assembled with Cu@G and carbon cloth maintains a stable cycling capacity for nearly 100 cycles at a high areal capacity of 5 mA h cm⁻² with a capacity retention ratio of nearly 100%. This work provides the possibility of high Zn utilization anode or Zn metal-free anode design for Zn-based batteries in energy storage systems.

剪切流诱导的石墨烯排列能够实现具有高可逆性的 (002) 织构锌金属阳极的最密堆积晶体学

锌金属的晶体取向与其沉积模式、电镀/剥离可逆性、HER和腐蚀有关。理论计算表明，Zn金属的(002)晶面不仅有利于镀/退锌的可逆性和抑制枝晶的生长，而且还具有抑制HER和碱性腐蚀的作用。使用剪切流感应连续制备米级石墨烯改性铜集流体（Cu@G）。 Cu@G 收集器选择性地锁定锌沉积物的晶格方向，从而实现 (002) 织构锌金属阳极的最密堆积晶体学。 SEM电子背散射衍射（EBSD）和XRD结果表明，Zn以超高且均匀的（002）取向沉积在Cu@G集流体表面。电化学测试结果表明，Cu@G集电极表现出优异的电镀/剥离可逆性和优异的累积电镀容量（在40 mA cm ^-2和2 mA h cm ^-2下>6900次循环，ACE高达99.977%，并且CPC 高达 13 860 mA h cm ^-2 )。 Zn ²⁺混合超级电容器（ZHS）和锌离子电池（ZIB）也表现出优异的性能（ZHS可循环使用>48 000次，容量保持率高达94.6%，ACE接近100%； Zn//PANI 全电池在 130 个循环后为 80.43%，CE 为 100%（N/P = 2.35）。我们还展示了带有改良Cu@G集电极的无阳极设计（即零过量Zn），并且这种由Cu@G和碳布组装的锌锰（MnO ₂）双镀电池保持了稳定的循环容量在5 mA h cm ^-2的高面积容量下循环近100次，容量保持率接近100%。这项工作为储能系统中的锌基电池提供了高锌利用率阳极或无锌金属阳极设计的可能性。
