Electrolyte, which is regarded as the “blood” of batteries, has a direct impact on reaction kinetics, mass transport, and side reactions and thus plays a key role in determining the electrochemical performance of Zn electrodes. Therefore, considerable efforts have been devoted to modulating the electrolytes to improve the performance of Zn electrodes. Although significant progress has been made, achieving stable and highly reversible Zn electrodes remains a critical challenge. This review aims to provide a systematic summary and discussion on electrolyte strategies for highperformance aqueous Zn batteries. The(electro)-chemical behavior and fundamental challenges of Zn electrodes in aqueous electrolytes are first discussed. Electrolyte modulation strategies developed to address these issues are then classified and elaborated according to the underlying mechanisms.Finally, remaining challenges and promising future research directions on aqueous electrolyte engineering are highlighted. This review offers insights into the design of highly efficient electrolytes for new generation of rechargeable Zn batteries.展开更多

However, the explorations for the most competitive manganese-based cathode materials of AZIBs have been mainly limited to some known manganese oxides. Herein, we report a new type of cathode material NH_(4)MnPO_(4)·H_(2)O(abbreviated as AMPH) for rechargeable AZIBs synthesized through a simple hydrothermal method. An in-situ electrochemical strategy inducing Mn-defect has been used to unlock the electrochemical activity of AMPH through the initial charge process, which can convert poor electrochemical characteristic of AMPH towards Zn^(2+)and NH_(4)+into great electrochemically active cathode for AZIBs. It still delivers a reversible discharge capacity up to 90.0 m Ah/g at 0.5 A/g even after 1000thcycles, which indicates a considerable capacity and an impressive cycle stability. Furthermore, this cathode reveals an(de)insertion mechanism of Zn^(2+)and NH_(4)+without structural collapse during the charge/discharge process. The work not only supplements a new member for the family of manganese-based compound for AZIBs, but also provides a potential direction for developing novel cathode material for AZIBs by introducing defect chemistry.展开更多

文摘As a general problem in the field of batteries,materials produced on a large industrial scale usually possess unsatisfactory electrochemical performances.Among them,manganese-based aqueous rechargeable zinc-ion batteries(ARZBs)have been emerging as promising large-scale energy storage systems owing to their high energy densities,low manufacturing cost and intrinsic high safety.However,the direct application of industrial-scale Mn2O3(MO)cathode exhibits poor electrochemical performance especially at high current rates.Herein,a highly reversible Mn-based cathode is developed from the industrial-scale MO by nitridation and following electrochemical oxidation,which triples the ion diffusion rate and greatly promotes the charge transfer.Notably,the cathode delivers a capacity of 161 m Ah g^(-1) at a high current density of 10 A g^(-1),nearly-three times the capacity of pristine MO(60 m Ah g^(-1)).Impressive specific capacity(243.4 m Ah g^(-1))is obtained without Mn^(2+) additive added in the electrolyte,much superior to the pristine MO(124.5 m Ah g^(-1)),suggesting its enhanced reaction kinetics and structural stability.In addition,it possesses an outstanding energy output of 368.4 Wh kg^(-1) at 387.8 W kg^(-1),which exceeds many of reported cathodes in ARZBs,providing new opportunities for the large-scale application of highperformance and low-cost ARZBs.

文摘Dendrite formation and side reactions,which originate from uncontrolled zinc(Zn)nucleation and growth and high water activity,remain the two critical challenges that hinder the practical implementation of Zn anodes for rechargeable aqueous batteries.In this work,we propose a cation and anion comodulation strategy to realize highly textured and durable Zn anodes.As a proof of concept,1-ethyl-1-methylpyrrolidinium bromide(MEPBr)is selected as a versatile additive to regulate Zn deposition.Specifically,MEP^(+)cations with preferential adsorption on tips/edges first promote uniform primary Zn nucleation on the substrate,followed by dynamic“edge shielding”of existing deposits to guide highly oriented Zn growth.Meanwhile,the incorporation of Br^(-)anions promotes the enrichment of Zn^(2+)at the electrode-electrolyte interface(EEI),thereby facilitating Zn deposition kinetics.In addition,both the preferentially adsorbed MEP^(+)cations and Br^(-)anions create a water-poor EEI while the two ionic species disrupt the original hydrogen bond network and reduce water within the solvation structure in the bulk electrolyte through ion-water interactions,thus dramatically reducing water-induced side reactions.As a result,the Zn//Zn symmetric battery with the MEPBr-modulated electrolyte exhibits a remarkable lifespan of over 4000 h at 2 m A cm^(-2)and 1 mA h cm^(-2).More excitingly,the newly designed electrolyte enables a Zn//NaV_(3)O_(8)·1.5H_(2)O full battery with a thin Zn anode(50μm)and a high mass-loading cathode(~10 mg cm^(-2))to operate normally for over 300 cycles with remarkable capacity retention,showcasing its great potential for practical applications.

文摘The electric double layer(EDL)at the electrochemical interface is crucial for ion transport,charge transfer,and surface reactions in aqueous rechargeable zinc batteries(ARZBs).However,Zn anodes routinely encounter persistent dendrite growth and parasitic reactions,driven by the inhomogeneous charge distribution and water-dominated environment within the EDL.Compounding this,classical EDL theory,rooted in meanfield approximations,further fails to resolve molecular-scale interfacial dynamics under battery-operating conditions,limiting mechanistic insights.Herein,we established a multiscale theoretical calculation framework from single molecular characteristics to interfacial ion distribution,revealing the EDL’s structure and interactions between different ions and molecules,which helps us understand the parasitic processes in depth.Simulations demonstrate that water dipole and sulfate ion adsorption at the inner Helmholtz plane drives severe hydrogen evolution and by-product formation.Guided by these insights,we engineered a“water-poor and anion-expelled”EDL using 4,1’,6’-trichlorogalactosucrose(TGS)as an electrolyte additive.As a result,Zn||Zn symmetric cells with TGS exhibited stable cycling for over 4700 h under a current density of 1 mA cm^(−2),while NaV_(3)O_(8)·1.5H_(2)O-based full cells kept 90.4%of the initial specific capacity after 800 cycles at 5 A g^(−1).This work highlights the power of multiscale theoretical frameworks to unravel EDL complexities and guide high-performance ARZB design through integrated theory-experiment approaches.

文摘Aqueous rechargeable zinc-ion batteries(ZIBs)have recently attracted increasing research interest due to their unparalleled safety,fantastic cost competitiveness and promising capacity advantages compared with the commercial lithium ion batteries.However,the disputed energy storage mechanism has been a confusing issue restraining the development of ZIBs.Although a lot of efforts have been dedicated to the exploration in battery chemistry,a comprehensive review that focuses on summarizing the energy storage mechanisms of ZIBs is needed.Herein,the energy storage mechanisms of aqueous rechargeable ZIBs are systematically reviewed in detail and summarized as four types,which are traditional Zn^(2+)insertion chemistry,dual ions co-insertion,chemical conversion reaction and coordination reaction of Zn^(2+)with organic cathodes.Furthermore,the promising exploration directions and rational prospects are also proposed in this review.
文摘Featuring low cost, high abundance, low electrochemical potential, and large specific capacity, zinc(Zn)metal holds great potential as an anode material for next-generation rechargeable aqueous batteries.However, the poor reversibility resulting from dendrite formation and side reactions poses a major obstacle for its practical application. Electrolyte, which is regarded as the “blood” of batteries, has a direct impact on reaction kinetics, mass transport, and side reactions and thus plays a key role in determining the electrochemical performance of Zn electrodes. Therefore, considerable efforts have been devoted to modulating the electrolytes to improve the performance of Zn electrodes. Although significant progress has been made, achieving stable and highly reversible Zn electrodes remains a critical challenge. This review aims to provide a systematic summary and discussion on electrolyte strategies for highperformance aqueous Zn batteries. The(electro)-chemical behavior and fundamental challenges of Zn electrodes in aqueous electrolytes are first discussed. Electrolyte modulation strategies developed to address these issues are then classified and elaborated according to the underlying mechanisms.Finally, remaining challenges and promising future research directions on aqueous electrolyte engineering are highlighted. This review offers insights into the design of highly efficient electrolytes for new generation of rechargeable Zn batteries.

文摘Aqueous Zn-ion battery has emerged as one of the most prospective energy storage devices due to its low cost,high safety,and eco-friendliness.However,Zn-ion batteries are bottlenecked by significant capacity fading during long-term cycling and poor performance at high current rates.Here,we report an available cooperation of multivariate manganese oxides@carbon hybrids(MnO_(2)/MnO@C and MnO_(2)/Mn_(3)O_(4)@C)via a plasma-assisted design as an attractive Zn-ion cathode.Among them,the MnO_(2)/MnO@C cathode exhibits a reversible specific capacity of 165 m Ah g^(-1)over 200 cycles at a high rate of 0.5 A g^(-1),and possesses great rate performance with high capacities of 110 and 100 m Ah g^(-1)at a high rate of 0.8 and 1 A g^(-1),respectively.The good cathode performance significantly results from the facile charge transfer and ions(Zn^(2+)and H^(+))insertion in the manganese oxides/carbon hybrids featuring phase stability behavior in the available cooperation of multivalence and carbon conductive substrates.This work will promote the Zn-manganese dioxide system for the design of low-cost and high-performance aqueous rechargeable Zn-ion batteries.

文摘Aqueous zinc ion batteries(AZIBs) with the merits of low cost, low toxicity, high safety, environmental benignity as well as multi-valence properties as the large-scale energy storage devices demonstrate tremendous application prospect. However, the explorations for the most competitive manganese-based cathode materials of AZIBs have been mainly limited to some known manganese oxides. Herein, we report a new type of cathode material NH_(4)MnPO_(4)·H_(2)O(abbreviated as AMPH) for rechargeable AZIBs synthesized through a simple hydrothermal method. An in-situ electrochemical strategy inducing Mn-defect has been used to unlock the electrochemical activity of AMPH through the initial charge process, which can convert poor electrochemical characteristic of AMPH towards Zn^(2+)and NH_(4)+into great electrochemically active cathode for AZIBs. It still delivers a reversible discharge capacity up to 90.0 m Ah/g at 0.5 A/g even after 1000thcycles, which indicates a considerable capacity and an impressive cycle stability. Furthermore, this cathode reveals an(de)insertion mechanism of Zn^(2+)and NH_(4)+without structural collapse during the charge/discharge process. The work not only supplements a new member for the family of manganese-based compound for AZIBs, but also provides a potential direction for developing novel cathode material for AZIBs by introducing defect chemistry.

文摘Photo-rechargeable batteries based on photocathodes that have the dual function of collecting and storing solar energy offer an efficient method for solar energy utilization.Herein,NiCo-layered double hydroxides(NiCo-LDH)/ZnIn_(2)S_(4)/carbon nanotubes(CNTs)(recorded as CZN),a heterostructure photocathode,has been synthesized by layer-by-layer growth for photo-driven rechargeable aqueous zinc batteries(AZBs).The proposed photocathode exhibits typical photoelectric properties and offers the following advantages:good photoresponse in the visible light range,energy level/potential matching between ZnIn_(2)S_(4) and NiCo-LDH,and the conductive network formed by CNTs to promote charge transfer.The photo-driven rechargeable AZBs can harvest solar energy and store charge simultaneously,showing enhanced energy storage capability under illumination.The discharge capacity reaches 274.8 mAh·g^(-1) with a high photo-conversion efficiency of 1.120% at 8.0 A·g^(-1)(100 mW·cm^(-2),white light).In particular,the photo-driven rechargeable AZBs can be charged by light solely,achieving a discharge capacity of 116.3 mAh·g^(-1).This study shows that the novel design and synthesis of the heterostructure photocathode is crucial and significant to enhancing the practicality of solar energy.

文摘Aqueous rechargeable sodium ion batteries(ARSIBs),with intrinsic safety,low cost,and greenness,are attracting more and more attentions for large scale energy storage application.However,the low energy density hampers their practical application.Here,a battery architecture designed by bipolar electrode with graphite/amorphous carbon film as current collector shows high energy density and excellent rate-capability.The bipolar electrode architecture is designed to not only improve energy density of practical battery by minimizing inactive ingredient,such as tabs and cases,but also guarantee high rate-capability through a short electron transport distance in the through-plane direction instead of in-plane direction for traditional cell architecture.As a proof of concept,a prototype pouch cell of 8 V based on six Na_(2)MnFe(CN)_(6)||NaTi_(2)(PO_(4))_(3)bipolar electrodes stacking using a“water-in-polymer”gel electrolyte is demonstrated to cycle up to 4,000 times,with a high energy density of 86 Wh·kg^(−1)based on total mass of both cathode and anode.This result opens a new avenue to develop advance high-energy ARSIBs for grid-scale energy storage applications.

文摘Aqueous rechargeable batteries are a possible strategy for large-scale energy storage systems.However,limited choices of anode materials restrict their further application.Here we report phenazine(PNZ)as stable anode materials in different alkali-ion(Li+,Na+,K+)electrolyte.A novel full cell is assembled by phenazine anode,Na0.44MnO2 cathode and 10 M NaOH electrolyte to further explore the electrochemical performance of phenazine anode.This battery is able to achieve high capacity(176.7 mAh·g^−1 at 4 C(1.2·Ag^−1)),ultralong cycling life(capacity retention of 80%after 13,000 cycles at 4 C),and excellent rate capacity(92 mAh·g^−1 at 100 C(30 A·g^−1)).The reaction mechanism of PNZ during charge—discharge process is demonstrated by in situ Raman spectroscopy,in situ Fourier transform infrared(FTIR)spectroscopy,X-ray photoelectron spectroscopy(XPS)and density functional theory(DFT)calculations.Furthermore,the system is able to successfully operate at wide temperature range from−20 to 70°C and achieves remarkable electrochemical performance.

文摘Despite the advances of aqueous zinc(Zn)batteries as sustainable energy storage systems,their practical application remains challenging due to the issues of spontaneous corrosion and dendritic deposits at the Zn metal anode.In this work,conformal growth of zinc hydroxide sulfate(ZHS)with dominating(001)facet was realized on(002)plane-dominated Zn metal foil fabricated through a facile thermal annealing process.The ZHS possessed high Zn^(2+)conductivity(16.9 mS cm^(-1))and low electronic conductivity(1.28×10^(4)Ωcm),and acted as a heterogeneous and robust solid electrolyte interface(SEI)layer on metallic Zn electrode,which regulated the electrochemical Zn plating behavior and suppressed side reactions simultaneously.Moreover,low self-diffusion barrier along the(002)plane promoted the 2D diffusion and horizontal electrochemical plating of metallic Zn for(002)-textured Zn electrode.Consequently,the as-achieved Zn electrode exhibited remarkable cycling stability over 7000 cycles at 2 mA cm^(-2)and 0.5 mAh cm^(-2)with a low overpotential of 25 mV in symmetric cells.Pairing with a MnO_(2)cathode,the as-achieved Zn electrode achieved stable cell cycling with 92.7%capacity retention after 1000 cycles at 10 C with a remarkable average Coulombic efficiency of 99.9%.

文摘The limitation of areal energy density of rechargeable aqueous hybrid batteries(RAHBs)has been a significant longstanding problem that impedes the application of RAHBs in miniaturized energy storage.Constructing thick electrodes with optimized geometrical properties is a promising strategy for achieving high areal energy density,but the sluggish ion/electron transfer and poor mechanical stability,as well as the increased electrode thickness,itself present well-known problems.In this work,a 3D printing technique is introduced to construct an ultra-thick lithium iron phosphate(LFP)/carboxylated carbon nanotube(CNT)/carboxyl terminated cellulose nanofiber(CNF)composite electrode with uncompromised reaction kinetics for high areal energy density Li–Zn RAHBs.The uniformly dispersed CNTs and CNFs form continuous interconnected 3D networks that encapsulate LFP nanoparticles,guaranteeing fast electron transfer and efficient stress relief as the electrode thickness increases.Additionally,multistage ion diffusion channels generated from the hierarchical porous structure assure accelerated ion diffusion.As a result,LFP/Zn hybrid pouch cells assembled with 3D printed electrodes deliver a well-retained reversible gravimetric capacity of about 143.5 mAh g^(-1) at 0.5 C as the electrode thickness increases from 0.52 to 1.56 mm,and establish a record-high areal energy density of 5.25 mWh cm^(-2) with an impressive utilization of active material up to 30 mg cm^(-2) for an ultra-thick(2.08 mm)electrode,which outperforms almost all reported zinc-based hybrid-ion and single-ion batteries.This work opens up exciting prospects for developing high areal energy density energy storage devices using 3D printing.
