Abstract The dendritic issue in aqueous zinc‐ion batteries (ZBs) using neutral/mild electrolytes has remained an intensive controversy for a long time: some researchers assert that dendrites severely exist while others claim great cycling stability without any protection. This is clarified by investigating charge/discharge‐condition‐dependent formation of Zn dendrites. Lifespan degradation (120 to 1.2 h) and voltage hysteresis deterioration (134 380 mV) are observed with increased current...
Abstract Hydrogel materials are receiving increasing research interest due to their intriguing structures that consist of a crosslinked network polymer chains with interstitial spaces filled solvent water. This feature endows the characteristics being both wet and soft, making them ideal candidates for electrolyte flexible energy storage devices, such as supercapacitors rechargeable batteries under intensive studies nowadays. More importantly, highly abundant tunable chemistries these...
Abstract Prussian blue analogue (PBA)‐type metal hexacyanoferrates are considered as significant cathodes for zinc batteries (ZBs). However, these PBA‐type cathodes, such cyanogroup iron hexacyanoferrate (FeHCF), suffer from ephemeral lifespan (≤1000 cycles), and inferior rate capability (1 A g −1 ). This is because the redox active sites of multivalent (Fe(III/II)) can only be very limited activated thus utilized. attributed to spatial resistance caused by compact cooperation interaction...
Abstract Current aqueous Zn batteries (ZBs) seriously suffer from dendrite issues caused by rough electrode surfaces. Despite significant efforts in prolonging lifespan of these batteries, little effort has been devoted to elimination commercial‐grade cathode loading mass. Instead, demonstrations have only done at the laboratory level (≤2 mg cm −2 ). Additionally, new dilemmas regarding change proton‐storage behavior and interface pulverization emerged turn. Herein, hydrogen‐substituted...
Abstract Stretchable devices need elastic hydrogel electrolyte as an essential component, while most hydrogels will lose their stretchability after being incorporated with strong alkaline solution. This is why highly stretchable zinc–air batteries have never been reported so far. Herein, super‐stretchable, flat‐ (800% stretchable) and fiber‐shaped (500% are first developed by designing alkaline‐tolerant dual‐network electrolyte. In the electrolyte, sodium polyacrylate (PANa) chains...
The exploitation of a high-efficient, low-cost, and stable non-noble-metal-based catalyst with oxygen reduction reaction (ORR) evolution (OER) simultaneously, as air electrode material for rechargeable zinc-air battery is significantly crucial. Meanwhile, the compressible flexibility prerequisite wearable or/and portable electronics. Herein, we present strategy via single-site dispersion an Fe-Nx species on two-dimensional (2D) highly graphitic porous nitrogen-doped carbon layer to implement...
Abstract Rechargeable aqueous zinc ion batteries (AZIBs), as a rising star in batteries, are restricted by the narrow voltage window and unsatisfactory reversibility, which dominated high activity of H 2 O molecules, side reaction, Zn dendrites, structural degeneration cathode. Electrolyte manipulation has seen great deal research recently, particularly various kinds organic molecules have been shown to achieve outstanding effects on stabilizing anode, yet exploration mechanism behind...
An electrochemical nitrate-based cell enables both ammonia production and energy supply.
Degradable energy storage systems (ESSs) have been proposed to tackle increasing e-wastes such as heavy metals and toxic organic electrolytes. However, currently reported degradable ESSs are scarce because it is very difficult make all of the electrochemical components they must be stable for storage. Here, we designed an all-component rechargeable Zn-MXene capacitor with outstanding anti-self-discharge function using zinc nanosheets Ti3C2 MXene electrodes. The whole can retain ca. 82.5%...
Abstract Nonmetallic ammonium (NH 4 + ) ions are applied as charge carriers for aqueous batteries, where hexagonal MoO 3 is initially investigated an anode candidate NH storage. From experimental and first‐principle calculated results, the battery chemistry proceeds with reversible building–breaking behaviors of hydrogen bonds between tunneled electrode frameworks, ammoniation/deammoniation mechanism dominated by nondiffusion‐controlled pseudocapacitive behavior. Outstanding electrochemical...
Abstract The electrocatalytic nitrate reduction reaction (NO 3 ‐RR) to ammonia (NH ) offers a promising alternative approach for NH production and nitrate‐based voltaic cells which can deliver both electricity as products, are also highly attractive. However, nitrate‐to‐NH conversion involves proton‐assisted multiple‐electron transfer process with considerable kinetic barrier, underlying the need efficient catalysts NO – RR. A Zn‐nitrate battery is reported enable “killing three birds one...
Solid electrolytes based on the polymer-grafted MXene eliminate dendrites and hydrogen evolution of ZIBs, endow ZIBs with up to 90 days shelf life.
Nonbattery behavior related phase transition of electrodes is usually not favorable for any batteries because it results in performance degradation at all times. Here, we demonstrate a zinc hybrid-ion battery (ZHIB) with an unusual capacity enhancement even within 18 000 cycles by employing V2CTX MXene as the cathode, enormously differing from reported counterparts initiated hundreds cycles. The dominated mechanisms are determined to be delamination and unexpected during cycling. Both...

Bending, stretching, or twisting of batteries has been widely researched. However, shear force inevitably applied on the during bending, twisting. Unfortunately, thus far, research analyzing resistance solid even enhancing never reported. Herein, sewable Zn-MnO2 battery based nanofibrillated cellulose (NFC)/ployacrylamide (PAM) hydrogel, electrodeposited...
An inter-halogen strategy is proposed to activate and stabilize the unrealized I<sup>0</sup>/I<sup>+</sup> redox in aqueous Zn ion batteries.
Multiple stretchability has never been demonstrated as supercapacitors because the hydrogel used cannot fully recover after being heavily deformed. Now, a highly reversibly stretchable all-polymer supercapacitor was fabricated using developed double network (DN hydrogel) electrolyte and pure polypyrrole (PPy) electrode. The DN provides excellent mechanical properties, which can be stretched up to 500 % many times then restore almost 100 of original length. To fabricate recoverable...

However, against the widely used 2D foil, in fact, powder is a more practical choice for Zn-based industrial applications, but related solutions are rarely investigated. Herein, we focus on disclose its unknown failure mechanism different from foils. By utilization flexible conductive Ti3C2Tx MXene flakes with...
Abstract Zn foil is widely used for studying the stability and dendrite formation behavior of anodes. The reported long cycling life rechargeable batteries (RZBs) obtained by testing a battery immediately after its fabrication neglecting aging effects. performance demonstrated cannot, however, have practical applications. Using as both working electrode current collector will cause many problems when scaled up. A powder (Zn‐P)/current configuration more practical. In this work, corrosion...
