“…The Zn atoms of (0002) Zn can have chemical bonding with the Se atoms in (111) ZnSe , which forms a complete, coherent interface (Figure d). This coherent interface and the total lattice match (100% match) are the highest coherent interface among the representative materials (Figure e) in previous literature. ,,− …”

“…6b). Our Sb@Cu substrates exhibit obvious advantages particularly in terms of the high areal capacity of 200 mAh cm −2 , which is about one to two orders of magnitude higher than the reported values 16,22,29,[32][33][34][36][37][38]51,52 . In addition, the high current density of 200 mA cm −2 and accumulated capacity of 5500 mAh cm −2 are among the best reported values, suggesting the great promises of the Zn-free Sb@Cu anode for high energy Zn batteries.…”

The development of Zn-free anodes to inhibit Zn dendrite formation and modulate high-capacity Zn batteries is highly applauded yet very challenging. Here, we design a robust two-dimensional antimony/antimony-zinc alloy heterostructured interface to regulate Zn plating. Benefiting from the stronger adsorption and homogeneous electric field distribution of the Sb/Sb2Zn3-heterostructured interface in Zn plating, the Zn anode enables an ultrahigh areal capacity of 200 mAh cm−2 with an overpotential of 112 mV and a Coulombic efficiency of 98.5%. An anode-free Zn-Br2 battery using the Sb/Sb2Zn3-heterostructured interface@Cu anode shows an attractive energy density of 274 Wh kg−1 with a practical pouch cell energy density of 62 Wh kg−1. The scaled-up Zn-Br2 battery in a capacity of 500 mAh exhibits over 400 stable cycles. Further, the Zn-Br2 battery module in an energy of 9 Wh (6 V, 1.5 Ah) is integrated with a photovoltaic panel to demonstrate the practical renewable energy storage capabilities. Our superior anode-free Zn batteries enabled by the heterostructured interface enlighten an arena towards large-scale energy storage applications.

“…In the CV analysis carried out with ZGPE-2 and ZGPE-5, the cell utilizing ZGPE-5 exhibited a reduced gap between cathodic and anodic peak potentials, coupled with an increased area under the anodic peak. [46] Differences in the electrochemical behaviors of ZGPE-2 and ZGPE-5 during the process of metal reduction are hypothesized to arise from variances in the interactions between ions dissolved in the electrolyte and the zwitterionic polymer matrix. To estimate the changes in properties of ZGPE depending on electrolyte concentration, FTIR analysis was conducted using a zwitterionic hydrogel, ZGPE-2, ZGPE-5, and aqueous solutions with 2 and 5 m ZnSO 4 , respectively (Figure S13, Supporting Information).…”

Aqueous zinc metal batteries (AZMBs) are emerging energy storage systems that are poised to replace conventional lithium‐ion batteries owing to their intrinsic safety, facile manufacturing process, economic benefits, and superior ionic conductivity. However, the issues of inferior anode reversibility and dendritic plating during operation remain challenging for the practical use of AZMBs. Herein, a gel electrolyte based on zwitterionic poly(sulfobetaine methacrylate) (poly(SBMA)) dissolved with different concentrations of ZnSO4 is proposed. Two‐dimensional correlation spectroscopy based on Raman analysis reveals an enhanced interaction priority between the polar groups in SBMA and the dissolved ions as electrolyte concentration increases, which establishes a robust interaction and renders homogeneous ion distribution. Attributable to the modified coordination, zwitterionic gel polymer electrolyte with 5 mol kg−1 of ZnSO4 (ZGPE‐5) facilitates stable zinc deposition and improves anode reversibility. By taking advantage of preferential coordination, a symmetrical cell evaluation employing ZGPE‐5 demonstrates a cycle life over 3600 h, where ZGPE‐5 also exerts a beneficial effect on the full cell cycling when assembled with Zn0.25V2O5 cathode. This study elucidates changes in the internal ion behavior that are dependent on electrolyte concentrations and pave the way for durable AZMBs.
