Rechargeable alkaline zinc-air batteries promise high energy density and safety but suffer from the sluggish 4 electron (e-)/oxygen (O2) chemistry that requires participation of water electrochemical irreversibility originating parasitic reactions caused by caustic electrolytes atmospheric carbon dioxide. Here, we report a zinc-O2/zinc peroxide (ZnO2) proceeds through 2e-/O2 process in nonalkaline aqueous electrolytes, which enables highly reversible redox batteries. This ZnO2 was made...
Hierarchical N/S-codoped carbon microspheres with expanded interlayer distance and enhanced conductivity are fabricated facilely from cellulose/polyaniline composite in a "green" low-cost route. This material achieves high reversible capacity of ≈280 mA h g−1 at 30 superior rate performance ≈130 10 A g−1, ultralong cycle life more than 3000 cycles as an anode for sodium-ion batteries, holding great promise economic large-scale energy storage. As service to our authors readers, this journal...
Low-cost and highly efficient bifunctional electrocatalysts for the hydrogen evolution reaction (HER) oxygen (OER) are intensively investigated overall water splitting. Herein, we combined experimental research with first-principles calculations based on density functional theory (DFT) to engineer NiCo2S4@NiFe LDH heterostructure interface enhancing water-splitting activity. The DFT exhibit strong interaction charge transfer between NiCo2S4 NiFe LDH, which change interfacial electronic...
Abstract High nickel content in LiNi x Co y Mn z O 2 (NCM, ≥ 0.8, + = 1) layered cathode material allows high specific energy density lithium-ion batteries (LIBs). However, Ni-rich NCM cathodes suffer from performance degradation, mechanical and structural instability upon prolonged cell cycling. Although the use of single-crystal can mitigate these drawbacks, ion-diffusion large particles hamper its rate capability. Herein, we report a strategy to construct an situ Li 1.4 Y 0.4 Ti 1.6 (PO 4...
Abstract High-capacity Ni-rich layered oxides are promising cathode materials for secondary lithium-based battery systems. However, their structural instability detrimentally affects the performance during cell cycling. Here, we report an Al/Zr co-doped single-crystalline LiNi 0.88 Co 0.09 Mn 0.03 O 2 (SNCM) material to circumvent issue. We found that soluble Al ions adequately incorporated in SNCM lattice while less Zr prone aggregate outer surface layer. The synergistic effect of co-doping...
The lithium metal anode is considered as the ultimate choice for high-energy-density batteries. However, organic-dominated solid electrolyte interphase (SEI) formed in carbonate electrolytes has a low interface energy against metallic Li well high resistance, resulting plating/stripping Coulombic efficiency (CE) of less than 99.0% and severe dendrite growth. Herein, inorganic-enhanced LiF-Li3N SEI designed commercial 1 M LiPF6/EC-DMC by introducing nitrate (LiNO3) fluoroethylene (FEC)...
Abstract In recent years, rechargeable aqueous zinc‐ion batteries (ZIBs) have received much attention. However, the disproportionation effect of Mn 2+ seriously affects capacity retention ZIBs during cycling. Here, 3 O 4 cathode is improved by effective valence engineering. The engineering caused bulk oxygen defects, which are in situ derived from Mn‐metal organic framework carbonization. Bulk defects can change (MnO 6 ) octahedral structure, improves structural stability and inhibits...
Abstract Pseudocapacitance is a Faradaic process that involves surface or near redox reactions. Increasing the pseudocapacitive contribution one of most effective means to improve rate performance electrode materials. In this study, graphene oxide used as template in situ synthesize burr globule‐like FeSe 2 /graphene hybrid (B‐FeSe /G) using facile one‐step hydrothermal method. Structural characterization demonstrates layers not only wrap surfaces particles, but also stretch into interior...
Abstract Aqueous Zn batteries promise high energy density but suffer from dendritic growth and poor low‐temperature performance. Here, we overcome both challenges by using an eutectic 7.6 m ZnCl 2 aqueous electrolyte with 0.05 SnCl additive, which in situ forms a zincophilic/zincophobic Sn/Zn 5 (OH) 8 Cl ⋅H O bilayer interphase enables low temperature operation. Zincophilic Sn decreases plating/stripping overpotential promotes uniform plating, while zincophobic top‐layer suppresses dendrite...

Abstract The reaction kinetics of alkaline hydrogen evolution reactions (HER) is a trade‐off between adsorption and desorption for intermediate species (H 2 O, OH, H ads ). However, due to the complicated correlation intermediates energy electronic states, targeted regulating at atomic level not comprehensive. Herein, nonmetals (B, N, F) are used modulate structure Ni 3 S 4 , propose that O OH correlate directly with d‐band center (ε d ) transition metal Ni, has linear dependence on p‐band p...
Abstract Aqueous rechargeable Zn – MnO x batteries are very attractive due to their low‐cost and high energy density. However, Mn(III) disproportionation Jahn–Teller distortion can induce Mn(II) dissolution irreversible phase changes, greatly deteriorating the cycling life. Herein, a multi‐valence cobalt‐doped Mn 3 O 4 (Co‐Mn ) with capacity reversibility, which lies in multiple roles of various states doped cobalt, is reported. The Co 2+ doping between change product δ‐MnO 2 layer acts as...
Lithium–sulfur (Li–S) batteries suffer from sluggish sulfur redox reactions under high-sulfur-loading and lean-electrolyte conditions. Herein, a typical Co@NC heterostructure composed of Co nanoparticles semiconductive N-doped carbon matrix is designed as model Mott–Schottky catalyst to exert the electrocatalytic effect on electrochemistry. Theoretical experimental results reveal redistribution charge built-in electric field at heterointerface, which are critical lowering energy barrier...
Abstract Rechargeable multivalent metal ( e.g ., Ca, Mg or, Al) batteries are ideal candidates for large–scale electrochemical energy storage due to their intrinsic low cost. However, practical application is hampered by the reversibility, dendrite growth at anodes, sluggish multivalent–ion kinetics in oxide cathodes and, poor electrode compatibility with non–aqueous organic–based electrolytes. To circumvent these issues, here we report various aqueous comprising of concentrated gel...
Metal anodes represent as a prime choice for the coming generation rechargeable batteries with high energy density. However, daunting challenges including electrode volume variation and inevitable side reactions preclude them from becoming viable technology. Here, facile replacement reaction was employed to fabricate three-dimensional (3D) interdigitated metal/solid electrolyte composite electrode, which not only provides stable host structure buffering change within but also prevents by...
