aqueous rechargeable multiple metal-ion storage battery (ARSB) has a large potential in energy storage devices due to their safe usage, low cost and high rate capability. Nevertheless, the performance of practical ARSB is largely restricted by low capacity and limited cathode materials. Herein, we demonstrate an efficient cathode material based on Co Ni-layered double hydroxide (LDH) nanosheets arrays with abundant hydrogen vacancy induced by electrochemical activation process for high performance of cations storage. Consequently, the electrochemical activated Co Ni-LDH (ECA-Co Ni-LDH) nanosheets arrays exhibit high metal ion (Li^(+), Na^(+), Zn^(2+), Mg^(2+) and Ca^(2+)) storage capacities, which is 9 times and 3 times higher that of unactivated Co Ni-LDH arrays and ECA-Co Ni-LDH without hierarchical structure, respectively.Moreover, the ECA-Co Fe-LDH also shows the possibility for practical applications in actual batteries.By coupling with a Fe_(2)O_(3)/C anode, the assembled aqueous battery delivered a large energy density of 184.4 Wh kg^(-1)at power density of 4 Wh kg^(-1) in high voltage range of 0–2 V. To our best knowledge, such high energy density and large working window of our assembled aqueous battery is exceeded other LDH-based aqueous battery or supercapacitor, and the energy density almost comparable than that of commercial Li-ion batteries. Moreover, almost no measurable capacitance losses can be detected even after 10000 cycles. In addition, this work also provides a strategy to develop a high energy density cathode for multiple metal-ion storage batteries.

As an effective energy storage technology, rechargeable batteries have long been considered as a promising solution for grid integration of intermittent renewables(such as solar and wind energy). However,their wide application is still limited by safety issue and high cost. Herein, a new battery chemistry is proposed to satisfy the requirements of grid energy storage. We report a simple Cu-Mn battery, which is composed of two separated current collectors in an H2SO4-CuSO4-MnSO4 electrolyte without using any membrane. The Cu-Mn battery shows an energy density of 40.8 Wh L-1, a super-long life of 10,000 cycles(without obvious capacity decay) and negligible self-discharge. And the capital cost of US$ 11.9 kWh-1 based on electrolyte is lower than any previous batteries. More importantly, the battery can still work smoothly during thermal abuse test and drill-through test, showing high safe nature. Furthermore, a combination system integrating the Cu-Mn battery and hydrogen evolution is also proposed, which is able to avoid the generation of explosive H2/O2 mixture, and presents an efficient approach for grid energy storage and conversion.

aqueous rechargeable batteries(ARBs)are generally safer than non-aqueous analogues,they are also less-expensive,and more friendly to the environment.However,the inherent disadvantage of the narrow electrochemical window of H2O seriously restricts the energy density and output voltage of ARBs,especially aqueous rechargeable Fe-based batteries.Herein,we introduce a new battery system:the anode contains C@Fe/Fe_(2)O_(3)composite,which is interfaced with an alkaline electrolyte;the cathode contains LiMn_(2)O_()in contact with a neutral electrolyte.A Li^(+)-conducting membrane is carefully selected to decouple the electrode-electrolyte,which effectively widens the electrochemical window to above 2.65 V,thereby enables an aqueous rechargeable iron battery.Its average output voltage is 1.83 V and its energy density is 235.3 Wh/kg at 549 W/kg.In this work,we propose the energy storage mechanism with the aid of density functional theory(DFT).The calculated reduction potential of the anode agrees with the experimental value.Furthermore,this battery system demonstrates long cycle lifespan of approximately 2500 cycles at 2 A/g,corresponding to a capacity retention of 82.1%.These results are very far superior than those of mainstream aqueous rechargeable Fe-based batteries,which guarantee future investigation for storing electricity energy.

Rechargeable metal-iodine batteries are an emerging attractive electrochemical energy storage technology that combines metallic anodes with halogen cathodes. Such batteries using aqueous electrolytes represent a viable solution for the safety and cost issues associated with organic electrolytes. A hybrid-electrolyte battery architecture has been adopted in a lithium-iodine battery using a solid ceramic membrane that protects the metallic anode from contacting the aqueous electrolyte. Here we demonstrate an eco-friendly, low-cost zinc-iodine battery with an aqueous electrolyte, wherein active I2 is confined in a nanoporous carbon cloth substrate. The electrochemical reaction is confined in the nanopores as a single conversion reaction, thus avoiding the production of I3- intermediates. The cathode architecture fully utilizes the active I2, showing a capacity of 255 mAh·g^-1 and low capacity cycling fading. The battery provides an energy density of -151 Wh·kg^-1 and exhibits an ultrastable cycle life of more than 1,500 cycles.

aqueous Mg ion batteries(AMIBs)show great potential in energy storage for their advantages of high capacity,abundant resource,and environmental friendliness.However,the development of AMIBs is limited due to the scarcity of suitable anode materials.In this study,a new polymer anode material(PNTAQ)with flower-like nanosheet structure is synthesized for aqueous Mg-Na hybrid-ion battery(AMNHIB).PNTAQ possess carbonyl functional groups which can be oxidized and reduced reversibly in aqueous solution containing alkaline metal ions.PNTAQ displays a discharge specific capacity of 245 mAh g^(−1)at 50 mA g^(−1)in 1 M MgCl_(2)+0.5 M NaCl electrolyte,which is much higher than that in single 1 M MgCl_(2)or 0.5 M NaCl electrolyte.Even cycling at 1000 mA g^(−1)for 1000 times,the capacity retention can still maintain at 87.2%.A full Mg-Na hybrid-ion cell is assembled by employingβ-MnO_(2)as cathode and PNTAQ as anode material,it exhibits a specific capacity of 91.6 mAh g^(−1)at 100 mA g^(−1).The polymer electrode material well maintains its framework structure during the discharge/charge cycling process of the hybrid-ion battery.

aqueous zinc-based battery is usually plagued by serious dendrites and side reactions including Zn corrosion and water decomposition on the anode.To address the drawbacks,constructing coating layers with high conductivity and anti-catalytic effects on hydrogen evolution reaction has been considered as an efficient strategy.Herein,cheap and abundant twodimensional(2D)conductive graphite(KS-6)coating layer with high electronic conductivity(~106 S·m^(−1))could directly form strong bonding with Zn foil due to high zincophilicity,which correspondingly protects Zn metal from liquid electrolyte to inhibit parasitic hydrogen evolution and guide uniform Zn electrodeposition during cycling.The KS-6 layer owns a profitable charge redistribution effect to endow Zn anode with a lower nucleation energy barrier and a more uniformly distributed electric field compared with bare Zn.Therefore,such integrated Zn anode exhibits low voltage hysteresis(~38 mV)and excellent cycling stability with dendrite-free behaviors(1 mA·cm^(−2)and 2 mAh·cm^(−2))over 2,000 h,far outperforming many reported Zn metal anodes in aqueous systems.Encouragingly,in light of the superior Zn@KS-6 anode,VNOx powders and Prussian blue analogs Mn_(2)Fe(CN)_(6)are applied as the cathode materials to assemble full batteries,which show remarkable cycling stabilities and high Coulombic efficiencies(CEs)over 200 cycles with capacity retention of 81.5%for VNOx//Zn@KS-6 battery and over 400 cycles with capacity retention of 94.6%for Mn_(2)Fe(CN)_(6)//Zn@KS-6 battery,respectively.

As an ideal carbon-free energy carrier,ammonia plays an indispensable role in modern society.The conventional industrial synthesis of NH3 by the Haber-Bosch technique under harsh reaction conditions results in serious energy consumption and environmental pollution.Therefore,it is essential to develop NH3 synthesis tactics under benign conditions.Electrochemical synthesis of NH_(3) has the advantages of mild reaction conditions and environmental friendliness,and has become a hotspot for research in recent years.It has been reported that zinc-nitrogen batteries(ZNBs),such as Zn-N_(2),Zn-NO,Zn-NO_(3)^(-),and Zn-NO_(2)^(-)batteries,can not only reduce nitrogenous species to ammonia but also have concomitant power output.However,the common drawbacks of these battery systems are unsatisfactory power density and ammonia production.In this review,the latest progress of ZNBs including the reaction mechanism of the battery and reactor design principles is systematically summarized.Subsequently,active site engineering of cathode catalysts is discussed,including vacancy defects,chemical doping,and heterostructure engineering.Finally,some insights are provided to improve the performance of ZNBs from a practical perspective of view.

aqueous Mg-ion batteries(MIBs)are safe,non-toxic and low-cost.Magnesium has a high theoretical specific capacity with its ion radius close to that of lithium.Therefore,aqueous magnesium ion batteries have great research advantages in green energy.To acquire the best electrode materials for aqueous magnesium ion batteries,it is necessary for the structural design in material.Fe_(2)O_(3)is an anode material commonly used in Li-ion battery.However,the nano-cube Fe_(2)O_(3)combined with graphene hydrogels(GH)can be successfully prepared and employed as an anode,which is seldom researched in the aqueous batteries system.The Fe_(2)O_(3)/GH is used as anode in the dual MgSO_(4)+FeSO_(4)aqueous electrolyte,avoiding the irreversible deintercalation of magnesium ions.In addition,the Fe element in anode material can form the Fe^(3+)/Fe^(2+)and Fe^(2+)/Fe^(3+)redox pairs in the MgSO_(4)+FeSO_(4)electrolyte.Thus,the reversible insertion/(de)insertion of magnesium and iron ions into/from the host anode material can be simultaneously achieved.After the initial charge,the anodic structure is changed to be more stable,avoiding the formation of MgO.The Fe_(2)O_(3)/GH demonstrates high rate properties and reversible capacities of 198,151,121,80,75 and 27 mAh g^(−1)at 50,100,200,300,500 and 1000 mA g^(−1)correspondingly.

Insights into the Structure Stability of Prussian Blue for aqueous Zinc Ion Batteries

The reversible storage of Zn^(2+)ions in Prussian blue analogues with typical aqueous solution was challenged by fast degradation and poor coulombic efficiency,while the mechanism is yet to be uncovered.This study correlates the performance of the nickel hexacyanoferrate to the dynamics of H_(2)O in the electrolyte and the associated phase stability of the electrode.It demonstrates severe Ni dissolution in conventional diluted aqueous electrolyte(1 M ZnSO^(4)or 1 M Zn(TFSI)^(2)),leading to structure collapse with the formation of an electrochemical inert phase.This is regarded as the descriptor for the fast decay of nickel hexacyanoferrate in diluted aqueous electrolyte.However,a well-preserved open framework for zinc storage was obtained in concentrated aqueous electrolyte(1 M Zn(TFSI)_(2)+21 M LiTFSI)—the H_(2)O activity is highly suppressed by extensive coordination—thus,reversible capacity of 60.2 m Ah g^(-1)over 1600 cycles could be delivered.
