“…[7][8][9] Inorganic cathode materials still suffer from many limitations including dendrite growth, sluggish reaction kinetics and cycling stability. [10][11][12][13] For example, Mn-based oxides incur poor rate performance and rapid capacity fading resulting from terrible electrical conductivity and Mn 2+ dissolution in electrolytes. 14,15 V-based oxides are limited by the low charge/discharge voltage plateau and toxicity as well as high cost even though they usually exhibit better cycling performance than Mn-based oxides.…”

“…In addition, the TA@Zn maintains continuously steady voltage hysteresis during 200 cycles, whereas bare Zn shows fluctuated voltage curves owing to the spontaneous side reaction and the formation of dendrites ( Supplementary Figures S8, S9 ). The long cycle life coupled with the high CE of TA@Zn|Ti cells indicates reduced side reactions and improved reversibility with the assistance of the metal–chelate interphase ( Liu et al, 2022c ).…”

“…Moreover, the strong coordination between metal–chelate interphase and Zn 2+ ions enables fast desolvation kinetics of the hydrate Zn 2+ ions (Zn(H 2 O) 6 2+ ), mitigating the water-induced issues. In a word, the introduced metal–chelate interphase kinetically improves the Zn deposition qualities to realize a stable and dendrite-free Zn anode ( Liu et al, 2022a ).…”

Aqueous zinc-ion batteries (AZIBs) have attracted extensive attention because of their eco-friendliness, intrinsic safety, and high theoretical capacity. Nevertheless, the long-standing Zn anode issues such as dendrite growth, hydrogen evolution, and passivation greatly restrict the further development of AZIBs. Herein, a metal–chelate interphase with high Zn affinity is constructed on the Zn metal surface (TA@Zn) via dipping metallic Zn into a tannic acid (TA) solution to address the aforementioned problems. Benefiting from the abundant hydrophilic and zincophilic phenolic hydroxyl groups of TA molecules, the metal–chelate interphase shows strong attraction for Zn2+ ions, guiding uniform zinc deposition as well as decreasing Zn2+ migration barrier. Therefore, the TA@Zn anode displays an extended lifespan of 850 h at 1 mA cm−2, 1 mAh cm−2 in the Zn|Zn symmetrical cell, and a high Coulombic efficiency of 96.8% in the Zn|Ti asymmetric cell. Furthermore, the Zn|V2O5 full cell using TA@Zn anode delivers an extremely high capacity retention of 95.9% after 750 cycles at 2 A g−1. This simple and effective strategy broadens the interfacial modification scope on Zn metal anodes for advanced rechargeable Zn metal batteries.

“…Due to their intrinsic safety and low cost, aqueous rechargeable batteries have attracted significant research interest in recent years [1,2] . Due to the natural abundance, two-electron carrier potential, high theoretical capacity (820 mAh g -1 and 5855 mAh cm -3 ), nontoxicity and chemical stability of metallic Zn, aqueous zinc ion batteries (AZIBs) are experiencing vigorous development [3][4][5] . However, there are still many obstacles to the practical application of metallic zinc electrodes, including zinc dendrites, side reactions and the sluggish transport of Zn 2+ .…”

Despite the low cost, safety and high theoretical capacity of metallic zinc, zinc anodes face chronic problems, including zinc dendrites, corrosion and side reactions in aqueous zinc-ion batteries (ZIBs). Herein, a nitrogen-doped carbon nanoparticle coating layer derived from discarded cigarette filters is constructed to suppress parasitic side reactions and zinc dendrite growth. The dense coating layer isolates water from the zinc anode, effectively inhibiting side reactions. Furthermore, the special micro-mesoporous structure and sufficient zincophilic groups guarantee uniform Zn stripping/plating. Consequently, durable cycle stability (2400 cycles at a current density of 1 mA cm-2) with a stable polarization potential is achieved for symmetrical cells. The coating layer derived in this study therefore has the potential to improve the electrochemical performance of ZIBs.
