Abstract ：
Aqueous zinc-ion batteries (AZIBs) are promising large-scale energy storage devices due to their costeffectiveness and high safety. However, the rampant dendrite growth and notorious side reactions resulting from the decomposition of active water molecules hinder its practical application. Herein, the zincophilic polyoltype surfactant of alkyl polyglycoside (APG) is introduced to induce the rearrangement of the H-bonds network to diminish the free water activity, facilitating the zinc-ion solvation structure transition from [Zn2+(H2O)6 & sdot;SO42-] (solvent separated ion pair, SSIP) to [Zn2+(H2O)5 & sdot;OSO32-] (contact ion pair, CIP) with less Zn2+-solvated H2O. Meanwhile, the APG molecular preferentially adsorb on the Zn surface to form a dehydrated layer, which can suppress the hydrogen evolution reaction (HER) and hinder the two-dimensional (2D) diffusion of Zn2+ ions. Consequently, the Zn//Zn symmetric cell using our designed electrolyte demonstrates an ultralong cycle life of 5250 h at 1.0 mA cm-2/1.0 mAh cm-2. Furthermore, the as-prepared Zn//Na2V6O16 & sdot;3H2O full cell also delivers a high-capacity retention rate of 80.8% even after 1000 cycles at 2.0 A g-1, superior to that of the full cell using pure ZnSO4 electrolyte. This study offers an effective strategy to modulate the cation solvation structure by rearranging the H-bonds network for a highly reversible Zn anode.

Abstract ：
The plateau-type sodium titanate with suitable sodiation potential is a promising anode candidate for high safe and high energy density of sodium-ion batteries (SIBs). However, the poor initial Coulombic efficiency (ICE) and cyclic instability of sodium titanate are attributed to the unstable interfacial structure along with the decomposition of electrolytes, resulting in the continuous formation of solid electrolyte interface (SEI) film. To address this issue, a chemical grafting method is developed to fabricate a highly stable interface layer of inert Al2O3 on the sodium titanate anode, rendering the high ICE and excellent cycling stability. Based on theoretical calculations, NaPF6 are more likely adsorption on the Al2O3 surface and produce sodium fluoride. The formation of a thin and dense SEI film with rich sodium fluoride achieves the low interfacial resistances and charge-transfer resistances. Benefitting from our design, the obtained sodium titanate exhibits a high ICE from 67.7 % to 79.4 % and an enhanced reversible capacity from 151 mAh g-1 to 181 mAh g-1 at 20 mA g-1, along with an increase in capacity retention from 56.5 % to 80.6 % after 500 cycles. This work heralds a promising paradigm for rational regulation of interfacial stability to achieve high-performance anodes for SIBs. A chemical grafting method is developed to fabricate a highly stable interface layer of inert Al2O3 on the sodium titanate anode, rendering the high initial Coulombic efficiency (ICE) and excellent cycling stability. This is due to the formation of a thin and dense solid-electrolyte interface (SEI) film with rich sodium fluoride, leading to the lower interfacial resistances and charge-transfer resistances.+ image

Abstract ：
Separators or electrolyte membranes are recognized as the key components to guarantee ion transport in rechargeable batteries. However, the ever-growing applications of the battery systems for diverse working environments bring new challenges, which require advanced battery membranes with high thermal stability, excellent mechanical strength, high voltage tolerance, etc. Therefore, it is highly desirable to design novel methods/concepts to solve the current challenges for battery membranes through understanding the mechanism of novel phenomena and electrochemical reactions in battery systems working under unconventional conditions. Recently, the new emerging Janus separators or electrolyte membranes with two or more distinct chemical/physical properties arising from their asymmetric structure and composition, are promising to address the above challenges via rational design of their targeted functionalities. To this end, in this review, we first briefly cover the current challenges of the traditional battery membrane for battery devices working in unconventional conditions. Then, the state-of-art developments of the rational design of Janus membranes to overcome the above challenges for diverse battery applications are summarized. Finally, we outline these latest developments, challenges, and future potential directions of the Janus membrane. Our review is aimed to provide basic guidance for developing functional separators or electrolyte membranes for advanced batteries.

Abstract ：
Aqueous zinc ion batteries are gaining popularity due to their high energy density and environmental friendliness. However, random deposition of zinc ions on the anode and sluggish migration of zinc ions on the interface would lead to the growth of zinc dendrites and poor cycling performance. To address these challenges, we developed a fluorinated solid-state-electrolyte interface layer composed of Ca5(PO4)3F/Zn3(PO4)2 via an in situ ion exchange strategy to guide zinc-ion oriented deposition and fast zinc ion migration on the anode during cycling. The introduction of Ca5(PO4)3F (FAP) can increase the nucleation sites of zinc ions and guide the oriented deposition of zinc ions along the (002) crystal plane, while the in situ formation of Zn3(PO4)2 during cycling can accelerate the migration of zinc ions. Benefited from our design, the assembled Zn//V2O5 & sdot; H2O batteries based on FAP-protected Zn anode (FAP-Zn) achieve a higher capacity retention of 84 % (220 mAh g-1) than that of bare-Zn based batteries, which have a capacity retention of 23 % (97 mAh g-1) at 3.0 A g-1 after 800 cycles. This work provides a new solution for the rational design and development of the solid-state electrolyte interface layer to achieve high-performance zinc-ion batteries. We developed a fluorinated solid electrolyte interfacial layer to guide the oriented deposition of zinc ions along the (002) crystal plane of Zn anode to inhibit the growth of zinc dendrites and accelerate the migration of zinc ions at the anode interface during cycling and improve the electrochemical performance of the battery.image

Abstract ：
The spontaneous parasitic reactions (hydrogen evolution, dendrite growth, etc.) of Zn metal hinder the commercial application of aqueous zinc ion batteries. Herein, a highly adhesive zinc-ion conductive buffer polymer layer is constructed using polyvinyl formal (PVF) to prevent these parasitic reactions to enhance the reversibility of Zn deposition. This dense artificial buffer layer can not only effectively isolate the direct contact between the anode and the electrolyte, but also accommodate volume expansion during Zn plating/stripping and guide the process of Zn nucleation. Specifically, this PVF layer increases the nucleation overpotential and promotes Zn2+ three-dimensional diffusion process to homogenize the Zn2+ flux underneath the layer. Hence, the PVF@Zn exhibits no dendrites and high cycling stability with a lifespan of 5200 h, which is a 35-fold enhancement compared with Zn, and can even run at an ultrahigh current density of 40.0 mA cm(-2). Moreover, the PVF@Zn||Na2V6O16 full cell maintains a specific capacity of 172.4 mA h g(-1) (2400 cycles at 1.0 A g(-1)). This proposed strategy provides a practical insight into designing an excellent-performance Zn anode by eliminating the parasitic reactions and modulating the nucleation of Zn deposition.

Abstract ：
The performance of zinc-ion batteries is severely hindered by the uncontrolled growth of dendrites and the severe side reactions on the zinc anode interface. To address these challenges, a weak-water-coordination electrolyte is realized in a peptone-ZnSO4-based electrolyte to simultaneously regulate the solvation structure and the interfacial environment. The peptone molecules have stronger interaction with Zn2+ ions than with water molecules, making them more prone to coordinate with Zn2+ ions and then reducing the active water in the solvated sheath. Meantime, the peptone molecules selectively adsorb on the Zn metal surface, and then are reduced to form a stable solid-electrolyte interface layer that can facilitate uniform and dense Zn deposition to inhabit the dendritic growth. Consequently, the Zn||Zn symmetric cell can exhibit exceptional cycling performance over 3200 h at 1.0 mA cm-2/1.0 mAh cm-2 in the peptone-ZnSO4-based electrolyte. Moreover, when coupled with a Na2V6O16 center dot 3H2O cathode, the cell exhibits a long lifespan of 3000 cycles and maintains a high capacity retention rate of 84.3% at 5.0 A g-1. This study presents an effective approach for enabling simultaneous regulation of the solvation structure and interfacial environment to design a highly reversible Zn anode. A weak-water-coordination electrolyte based on a peptone-ZnSO4-based electrolyte is designed to modulate the solvation structure of Zn2+ ions and interfacial environment. The peptone molecules can solvate with Zn2+ ions and eliminate the water molecules to decrease the water activity. Meanwhile, the peptone molecules selectively adsorb on the Zn metal surface, and then are reduced, forming a stable solid-electrolyte interface layer to enable uniform and dense Zn deposition.image
