The development of zinc-ion batteries with high energy density remains a great challenge due to the uncontrollable dendrite growth on their zinc metal *** anodes plated on the substrate have attracted increasing attention to alleviate these dendrite ***,we first point out that both the random crystal orientation and the low metal affinity of the substrate are important factors of zinc dendrite ***,the(1 O 1)fully preferred tin interface layer with high zinc affinity was fabricated by chemical tin plating on(1 O o)oriented *** tin decorated copper substrate can realize high reversible zinc plating/stripping behavior,and full cell using this zinc plated substrate can be operated for more than 1000 cycles with high capacity retention(85.3%)and low electrochemical *** proposed strategy can be also applied to lithium metal batteries,which demonstrates that the substrate orientation regulation and metal affinity design are the promising approaches to achieve dendrite-free metal anode and overcome the challenges of highly reactive metal anodes.

Aqueous Zn-ion batteries(AZIBs)are regarded as a promising alternative to the widely used lithium-ion batteries in large-scale energy storage *** researches on the development of novel aqueous electrolyte to improve battery performance have also attracted great interest since the electrolyte is a key com-ponent for Zn2+migration between cathode and ***,we briefly sum-marized and illuminated the recent development tendency of aqueous electrolyte for AZIBs,then deeply analyzed its existing issues(water decomposition,cathode dissolution,corrosion and passivation,and dendrite growth)and discussed the corresponding optimization strategies(pH regulation,concentrated salt solution,electrolyte composition design,and functional additives).The internal mecha-nisms of these strategies were further revealed and the relationships between issues and solutions were clarified,which could guide the future development of aqueous electrolytes for AZIBs.

Due to the unsatisfactory electrode/electrolyte interface,the metallic Zn dendrites and corrosion are easily induced,severely hindering the applications of zinc-ion batteries(ZIBs).Herein,a strategy that engineers the interfacial double layer by an extremely low concentration of sulfolane is proposed to tune the Zn stripping/plating *** is revealed that the highly-polar sulfolane can predominately occupy the inner Helmholtz layer over water,and then regulate the upcoming Zn2+to directly deposit ***,the widened Helmholtz layer can weaken the electric field intensity,which will generate more nucleation sites and reduce the nuclei radius,thereby promoting uniform zinc deposition as ***,corrosion byproducts can be inhibited since fewer water molecules can contact the Zn ***,the battery performance can be naturally *** an optimum amount of sulfolane,the Zn||Zn battery can operate for more than 1,100 h under1 m A cm^(-2)and 1 m Ah cm^(-2).And the as-constructed Zn||NaV_(3)O_(8)·1.5H_(2)O battery demonstrates considerably higher cycling stability than that without ***,this work has provided a deep insight into constructing a functional interfacial double layer to regulate zinc deposition,which can also act as a reference for other metal-based batteries.

Aqueous zinc anodes have attracted the attention of many researchers owing to their high safety,low cost,and high theoretical specific ***,its practical application is severely limited by the dendrite growth on zinc ***,we develop an intrinsically zincophobic barium-titanate protective layer with a porous structure to suppress the zinc dendrite formation by homogenizing the ion distribution on the anode surface,increasing the nucleation sites,and limiting the irregular zinc *** on these synergistic effects,the coated zinc anode can exhibit long cycle life(840 h at 0.5 mA/cm^(2) for 0.5 mAh/cm^(2))and low voltage hysteresis(36 mV).This work can provide a feasible direction for the design of intrinsically zincophobic coating materials to uniformize the zinc stripping and plating.

开发具有宽温度范围、无枝晶生长和耐腐蚀的电解质对于水系金属锌电池的实际应用至关重要.本研究开发了一种γ-戊内酯共溶剂,以扩大水系电解质的工作温度范围并稳定锌金属阳极的界面.这种弱溶剂作为强氢键配体和“稀释剂”,高效地打破了自由水分子之间的氢键,从而提高了电解液的温度耐受性和化学稳定性.同时,γ-戊内酯也可以吸附在阳极表面从而促进锌的成核和调节锌的生长织构,实现无枝晶的锌沉积.这种优化后的电解质可以使对称电池的寿命达到2160 h,并可以在-50~80℃的宽温度范围内稳定运行.相应的ZnⅡ活性炭电容器和ZnⅡ聚苯胺电池在8100和1600次循环后,容量保持率分别为92.5%和85%.这种弱溶剂调控氢键和锌离子的溶剂鞘的机制为先进的水系电解质的设计提供了新的见解.
