“…This indicates that Nafion–TiO 2 is effective in improving the reversibility of zinc. At harsh conditions of 10 mA cm –2 and 10 mAh cm –2 , the Nafion–TiO 2 battery can still cycle for 330 h (Figure b) . As a comparison, the battery lives are limited to 35 h with bare zinc foil cells and 63 h with Nafion cells.…”

Aqueous zinc-ion batteries (AZIBs) have gained significant attentions for their inherent safety and cost-effectiveness. However, challenges, such as dendrite growth and anodic corrosion at the Zn anode, hinder their commercial viability. In this paper, an organic−inorganic coating layer (Nafion−TiO 2 ) was introduced to protect the Zn anode and electrolyte interface. Briefly, Nafion effectively shields against the corrosion from water molecules through the hydrophobic wall of −CF 3 and guided zinc deposition from the −SO 3 functional group, while TiO 2 particles with a higher Young's modulus (151 GPa vs 120 GPa from Zn metal) suppress the zinc dendrite formation. As a result, with the protection of Nafion−TiO 2, the symmetrical Zn∥Zn battery shows an improved cycle life of 1,750 h at 0.5 mA cm −2 , and the full cell based on Zn∥MnO 2 shows a long cycle life over 1,500 cycles at 1 A g −1 . Our research offers a novel approach for protecting zinc metal anodes, potentially applicable to other metal anodes such as those in lithium and sodium batteries.

This is due to the features of Nafion−TiO 2 to inhibit dendrite growth and corrosion reactions.…”

“…Several studies have demonstrated that controlling and suppressing HER can significantly enhance the performance of AZMBs. [16][17][18][19][20][21][22][23] In a typical zinc-ion electrolyte, Zn 2 + forms octahedral [Zn(H 2 O) 6 ] 2 + complexes, where solvent (H 2 O) molecules can coordinate with the Zn 2 + center, resulting in the creation of "solvated water." Within the electrolyte bulk, besides solvated water, there are also free water molecules that do not participate in any coordination activities with Zn 2 + .…”

Despite the advantages of aqueous Zinc (Zn) metal batteries (AZMB), the development of practically relevant batteries is plagued by several issues like unwanted hydrogen evolution reaction (HER), corrosion of Zn substrate (insulating ZnO passivation layer), and dendrite growth. Controlling and suppressing HER strongly correlates with the long‐term cyclability of AZMBs. Therefore, a precise quantitative technique is needed to monitor the real‐time dynamics of hydrogen evolution during Zn electrodeposition. In this study, we quantify hydrogen evolution using in‐situ electrochemical mass spectrometry (ECMS). During the electrodeposition of zinc on a copper substrate at a current density of 1.5 mA/cm² for 600 seconds, 0.3% of the total charge is attributed to HER, while the rest contributes to zinc electrodeposition. This may seem like a small fraction, but it can be detrimental to the long‐term cycling performance of AZMBs. Furthermore, our results provide insights into the correlation between HER and the porous morphology of the electrodeposited zinc, unravelling the presence of trapped H2 and Zn corrosion during the charging process. This this study provides a powerful tool for evaluating electrolyte additives, salts, and electrode modifications aimed at enhancing long‐term stability and suppressing the HER in aqueous Zn batteries.
