Abstract The design of anode‐free zinc (Zn) batteries with high reversibility at areal capacity has received significant attention recently, which is quietly challenging yet. Here, a Zn alloyed interface through electroplating introduced, providing homogeneous prenucleation sites to stabilize subsequent nucleation and plating. By employing Zn–Cu alloy as module, the complementary simulations characterizations confirm that interfaces achieve electric field distribution greatly enhance stability anode. Accordingly, Zn//Zn–Cu@Cu half‐cells show long cycle life over 900 h an average Coulombic efficiency (CE) 99.8% 10 mAh cm −2 . assembled zinc–bromine (Zn–Br 2 ) battery exhibits attractive stable cycling 11 000 cycles 1 , while 1000 higher Excitingly, Zn–Br pouch cell operates stably 50 cycles, achieves successful integration photovoltaic systems. This constructed strategy offer new insights into potential for large‐scale energy storage applications.

Zn metal anodes in mildly acidic electrolytes usually suffer from a series of problems, including parasitic dendrite growth and severe side reactions, significantly limiting the utilization efficiency cycling life. A deep understanding stripping/plating process is essential to obtain high-efficiency long-life anodes. Here, factors affecting are revealed, suggesting that thermodynamic uniformity bulk structures promotes an orderly stripping process, fast kinetic diffusion rate on surface facilitates uniform deposition. Then, co-optimized strategy for stabilizing proposed, which confirmed effectively suppress reactions. Thus, modified display record-breaking lives 1200 200 h under ultrahigh efficiencies 80 93.5%, respectively. More importantly, using this anode enables us realize Ah-level pouch cells continuous cycles harsh conditions.
