Achieving Ultrahigh‐Rate Planar and Dendrite‐Free Zinc …
A flat anode surface was well maintained after 1200 cycles (at 4 mAh cm −2 per cycle) with minimal capacity loss, translating to an average coulombic efficiency (CE) of 99.94%. We have also demonstrated how this planar plating system can be used as a new, low-cost method to produce high-quality, high-density Zn single crystal at scale.
