Selenium is a considerable energy storage material, with presenting a one-step electrochemical reaction in a cheap carbonate-based electrolyte and providing a considerable capacity as a cathode. However, capacity loss and safety issues caused by volume changes during charge and discharge processes, as well as low mass loading, still hinder the practical development of selenium cathodes. Binder is one of the indispensable constitutions of the electrode and crucial for improving the electrochemical performance of the battery. Herein, we design an aqueous robust network binder by doping a trace amount of Fe 3+ ions into sodium alginate for durable lithium/sodium-selenium batteries for the first time. With the modified binder, the capacity of the battery is increased by more than 17% at a current of 0.2C. Furthermore, it can achieve the highest Se loading made by blade coating of up to 12 mg cm −2 , which brings ultra-high reversible areal capacity of 4.9 mAh cm −2 for lithium-selenium battery, and currently the highest reported reversible areal capacity currently of up to 5.6 mAh cm −2 for sodium-selenium battery. Such a well-designed binder can improve the electrochemical performance and areal capacity of selenium cathodes, thereby boosting the practical application of selenium cathodes for energy storage.

Aqueous Zn–Mn2+ electrolysis batteries utilizing the two-electron-transfer reaction between Mn2+ and MnO2 attract great attention because of their superior theoretical capacity (616 mAh g–1). However, the low conductivity of deposited MnO2 and the poor conversion efficiency of Mn2+/MnO2 inevitably result in limited areal capacity and unsatisfied cycling stability, which have become the main hurdles of aqueous Zn–Mn2+ batteries’ applications. Herein, we propose a novel Mn2+/I– hybrid cathode that couples the triiodide/iodide redox with the Mn2+/MnO2 redox to optimize the electrolysis kinetics. Because of the synergistically enhanced conversion reaction between Mn2+/I– and the promoter effect of I– to the dissolution of MnO2, this hybrid cathode not only exhibits fast reaction kinetics, thus demonstrating ultrahigh rate capability (100 mA cm–2), but also displays observably enhanced conversion efficiency up to 96.0% with excellent reversibility of 2000 cycles. Especially the superhigh areal capacity of 20 mAh cm–2 with more than 100 cycles among the reported static Zn–Mn2+ electrolysis batteries is demonstrated. The excellent battery performance as well as the facile electrode hybridization approach designed here paves the way for the practical applications of aqueous Zn batteries.

The integration of electronic devices has placed increasing demands on the low area occupancy, high areal capacity and safety of energy storage devices. Aqueous zinc ion batteries are expected to be used in highly integrated precision electronics due to their high safety, environmentally friendly and low cost advantages. However, the conventional coating method limits the structure and the areal capacity of electrodes. To address this issue, we design and fabricate a novel 3D printed reticular MnO 2 self-supporting cathode. Ascribed to the high mass loading and reticular structure of the reticular MnO 2 cathode, the AZIBs deliver a high areal capacity (3.43 mAh cm −2 at 2 mA cm −2 ). It is demonstrated that the reticular structure facilitates electrolyte storage and rapid diffusion of Zn 2+ and reduces charge transfer impedance. Furthermore, the 3D printing technology can realize layer-by-layer printing of electrodes. The areal capacity of the two-layer 3D reticular MnO 2 cathode is almost twice as high as that of 3D reticular MnO 2 . This work indicates the great potential of 3D printing technology in the design and fabrication of high-load electrodes with a high areal capacity and customized shapes.

Reversible and dendrite-free zinc (Zn) circulation is essential for longevous aqueous zinc-ion batteries (ZIBs) and greatly impacted by the property of Zn interface and electrolyte, especially when confronted with high current density and large area capacity. Herein, a hierarchical Zn interface is constructed by the preferential anion surfactant adsorption and reaction, and assists to reduce the interfacial energy and side reactions for enhanced diffusion kinetics and reversibility during Zn plating/stripping. Thus, highly reversible and smooth Zn anodes are achieved with a long-term stability of 5500 h at 1 mA cm −2 /1 mAh cm −2 , an impressive rate up to 40 mA cm −2 for 10 mAh cm −2 and a large cumulative plating capacity of 4.45 Ah cm −2 at 10 mA cm −2 in Zn symmetric cells. Even under a high depth of discharge of 60% (5.85/7.65 mAh cm −2 ), Zn symmetric batteries can still maintain ca. 800 h's life. The proposed countermeasure has also proved to be valid in prolonging the lifespan and stability of Zn-MnO 2 full batteries at both low and high cycling current densities.

Ternary nickel–cobalt sulfides with excellent electrical conductivity and high electrochemical activity can serve as ideal cathode materials for flexible hybrid supercapacitors. The electrochemical performance of the nickel–cobalt sulfides can be well tuned by different Ni and Co contents. Herein, nickel–cobalt sulfides with different Ni/Co ratios have been successfully prepared on carbon cloth (CC) by applying a two-step method: first the electrodeposition of hydroxide precursors on CC and then the subsequent sulphuration using a hydrothermal method. By systematically investigating the ratio effects of Ni and Co ions on the growth and capacity contribution of materials, the CoNi2S4/CC electrode presented a high utilization of electrochemically active sites, showing excellent electrochemical performance. The effect of different mass loadings of up to 18.80 mg cm−2 of CoNi2S4/CC on electrochemical performance was further investigated, and it was observed that the areal capacity is positively correlated with the mass loading. A high areal capacity of 11.11 C cm−2 at 2 mA cm−2 was observed for the synthesized CoNi2S4/CC with excellent rate capability and long cycle life. Furthermore, flexible hybrid supercapacitors with CoNi2S4-1000/CC as the positive electrode and activated carbon as the negative electrode deliver a maximum power density of 2.99 mW cm−2 at a 0.252 mW h cm−2 energy density and an outstanding cyclic stability. The results provide a novel route for preparing high-mass loading nickel–cobalt sulfide electrodes with outstanding areal capacity.

Zinc-based flow batteries (Zn-FBs) are promising candidates for large-scale energy storage because of their intrinsic safety and high energy density. Unlike that conventional flow batteries operate on the basis of liquid-liquid conversions, the Zn anode in Zn-FBs adopts a solid-liquid conversion reaction, presenting challenges such as dendrite formation, poor reversibility, and low areal capacity, limiting its long-duration energy storage (LDES) applications. Here, we developed a liquid metal (LM) electrode that evolves the deposition/dissolution reaction of Zn into an alloying/dealloying process within the LM, thereby achieving extraordinary areal capacity and dendrite-free Zn-FBs with outstanding cycling stability. Both Zn-I2 and Zn-Br2 flow batteries using LM electrodes exhibited an ultrahigh areal capacity of 640 milliampere-hours per square centimeter, corresponding to an ultralong discharge duration of ~16 hours, thus exceeding the LDES standard defined by the US Department of Energy. This study breaks the solid-liquid working mode of the Zn anode, offering an effective solution for LDES applications with Zn-FBs.

Designing cathodes with more electroactive materials is a promising way to improve the energy density of batteries while it is highly challenging due to their low electronic/ionic transport, poor structural integrity, and irreversible Li + consumption in full-cell configurations. Herein, we demonstrate a self-supporting cathode based on 3 dimensional MXene-Carbon nanotubes-Cellulose-LiFePO 4 (3D-MCC-LFP). The 3D-MCC-LFP cathodes demonstrate some distinct advantages over conventional LFP cathode (Con-LFP), including higher LFP loading (120 mg cm −2 ) and faster electronic/ionic transport (1.587 S cm −1 /1.18 × 10 −11 cm 2 S −1 ), which result in better electrochemical performance. Such as, the 3D-MCC-LFP 10 cathode (LFP loading is 10 mg cm −2 ) offers a significantly higher capacity of 0.86 mAh cm −2 at 5 C (1 C=170 mA g −1 ) than Con-LFP 10 of 0.05 mAh cm −2 , and a higher retaining capacity of 1.45 mAh cm −2 after 500 cycles at 1 C than Con-LFP 10 (1.16 mAh cm −2 ). Meanwhile, the 3D-MCC-LFP 120 cathode demonstrates an ultrahigh areal capacity of 19.2 mAh cm −2 . Furthermore, the assembled 3D-MCC-LFP 60 /SnO 2 full-cell demonstrates a high areal capacity of 6.3 mAh cm −2 at 1.6 mA cm −2 . Considering its traits of ultrahigh area capacity, excellent electronic/ionic transport and self-supporting characteristics, the 3D-MCC-LFP cathode combined with SnO 2 anode is surely promising for high performance lithium-ion batteries.

Aqueous Zn-based flow batteries often face issues such as poor reversibility and short lifespan due to irregular Zn deposition and detrimental side reactions. To address these challenges, we developed a zwitterionic gemini additive, N,N′-bis(3-propanesulfonic acid)-3,3′-bipyridinium (SPr-Bpy), to enhance Zn plating/stripping behavior and optimize the Zn2+ solvation structure. The dual sulfonate groups influence the Zn2+ solvation shell and anchor SPr-Bpy to the Zn surface through multi-site interactions. Additionally, the bipyridinium structure forms an electrostatic shielding layer, suppressing excessive Zn2+ accumulation, promoting uniform Zn deposition, and thus mitigating dendrite formation and hydrogen evolution. Consequently, the Zn||Zn symmetric cells exhibit an impressive lifespan of 250 h, while the Zn||Cu asymmetric cells achieve a high average Coulombic efficiency of 99.8% over 450 cycles. Moreover, SPr-Bpy significantly improves Zn/TEMPO flow battery performance, achieving a high areal capacity of 24.4 mAh cm-2 with an exceptional capacity retention of 99.992%/cycle over 500 cycles.

The ever-increasing electric vehicles and portable electronics make lithium-ion barreries (LIBs) toward high energy density, resulting in long driving range and standby times. Generally, excellent electrochemical performance can be obtained in thin electrode materials with low mass loadings (<1 mg cm −2 ), but it is difficult to be achieved in commercial electrodes with high mass loadings (>10 mg cm −2 ). In this work, we report a facile method for fabricating nitrogen doped carbon microtubes ( N -CMTs) consisted of crumped carbon nanosheets for high-performance LIBs with ultrahigh mass loading, where non-tubular biomass waste ( i.e. , peanut dregs) is employed as the precursor. Benefiting from the hollow tubular conductive network, high graphitization, and hierarchical structure, the as-synthesized N -CMTs exhibit ultrahigh area capacity of 6.27 mAh cm −2 at a current density of 1.5 mA cm −2 with a high mass loading of 15 mg cm −2 and superior cycling stability for LIBs. Our approach provides an effective strategy for the preparation of nitrogen-doped carbon microtubes to develope high energy LIBs with high mass loading electrodes.

The shuttling behavior and sluggish conversion kinetics of the intermediate lithium polysulfides (LiPSs) represent the main obstructions to the practical application of lithium–sulfur (Li–S) batteries. Herein, an anion-deficient design of antimony selenide (Sb 2 Se 3− x ) is developed to establish a multifunctional LiPS barrier toward the inhibition of polysulfide shuttling and enhancement of battery performance. The defect chemistry in the as-developed Sb 2 Se 3− x promotes the intrinsic conductivity, strengthens the chemical affinity to LiPSs, and catalyzes the sulfur electrochemical conversion, which are verified by a series of computational and experimental results. Attributed to these unique superiorities, the obtained LiPS barrier efficiently promotes and stabilizes the sulfur electrochemistry, thus enabling excellent Li–S battery performance, e.g., outstanding cyclability over 500 cycles at 1.0 C with a minimum capacity fading rate of 0.027% per cycle, a superb rate capability up to 8.0 C, and a high areal capacity of 7.46 mAh cm −2 under raised sulfur loading. This work offers a defect engineering strategy toward fast and durable sulfur electrochemistry, holding great promise in developing practically viable Li–S batteries as well as enlightening the material design of related energy storage and conversion systems.

Developing practical technical index of aqueous zinc metal batteries (ZMBs) is crucial to support safe large-scale energy storage. However, the realistic performance demonstration of ampere hour (Ah)-scale aqueous ZMBs under high mass loading and large areal capacity, which is the key to the industrial application of aqueous ZMBs, remains a critical challenge. In this paper, we propose a bilateral in-situ functionalization strategy in response to the issues that face high mass loading and large areal capacity of aqueous ZMBs. A gradient interface of Zn negative electrode was formed by directional adsorption and in-situ decomposition of organic sodium salt electrolyte additive. It avoids the influences from the fluctuation of electrolyte state and positive electrode dissolution, realizing uniform large-capacity plating/stripping in Ah-scale pouch cell. The positive electrode interface was also in-situ modified by electrolyte additive, which not only facilitated ion intercalation but also suppressed positive electrode dissolution through adsorption at the interface, thereby achieving high-loading stability. As a result, the cyclic stability in coin cell maintained more than 4000 cycles at 2 A g −1 , underscoring the superior compared to its counterpart. More importantly, the Ah-scale pouch cell can last more than 680 cycles with an accumulated capacity of 319.6 Ah. This work offers a roadmap for designing practical Ah-scale ZMB pouch cells.

Electrode materials are crucial for the electrochemical performance of supercapacitors. Thus, it is urgent to develop a satisfactory electrode material with excellent energy storage properties. Binary metal hydroxides are competitive candidates for supercapacitors. Herein, we prepared honeycomb-like NiCo(OH) 2 nanosheet arrays grown on nickel foam by a facile one-step solvothermal method. The electrochemical performance of as-prepared honeycomb-like NiCo(OH) 2 nanosheet arrays as electrode materials for supercapacitor have been evaluated. The NiCo(OH) 2 electrode exhibits higher areal capacity (267 mF cm −2 ) compared with Ni(OH) 2 (31.2 mF cm −2 ) and Co(OH) 2 (87.73 mF cm −2 ) at the current density of 20 mA cm −2 . The capacity retention can up to 83.8% after 5000 cycles. Such intriguing electrochemical performance enables it to be a potential electrode material for supercapacitors.
