Aqueous zinc-ion batteries (ZIBs) are competitive among the elective candidates for electrochemical energy storage systems, but the intrinsic drawbacks of zinc metal anodes such as dendrites and corrosion severely hinder their large-scale application. Developing alternative anode materials capable of high reversibility and stability for storing Zn2+ ions is a feasible approach to circumvent the challenge. Herein, a sulfur-defect-induced TiS1.94 (D-TiS1.94) as a promising intercalation anode material for ZIBs is designed. The abundant Zn2+-storage active sites and lower Zn2+ migration barrier induced by sulfur defects endow D-TiS1.94 with a high capacity for Zn2+-storage (219.1 mA h g–1 at 0.05 A g–1) and outstanding rate capability (107.3 mA h g–1 at 5 A g–1). In addition, a slight volume change of 8.1% is identified upon Zn2+ storage, which favors a prolonged cycling life (50.3% capacity remaining in 1500 cycles). More significantly, the D-TiS1.94||ZnxMnO2 full battery demonstrates a high discharge capacity of 155.7 mA h g–1 with a capacity retention of 59.8% in 400 cycles. It has been estimated that the high-capacity, low-operation voltage, and long-life D-TiS1.94 can be a promising component of the ZIB anode material family, and the strategy proposed in this work will provide guidance to the defect engineering of high-performance electrode materials toward energy storage applications.

An anode material with Li 4 Ti 5 O 12 nanocrystals entangled by carbon nanotubes is prepared by polymerization of titanium tetra-isopropoxide with ethylene glycol in the presentence of carbon nanotubes. The resulted polymer is hydrolyzed in LiOH/H 2 O solution, and then thermally decomposed to obtain the topic anode material. The characterizations show that the synthesis method yields a type of material that has both of high electronic conductivity and high lithium ion diffusion rate. The material has stable deep discharge capability (down to 0.01 V), high specific capacity (237 mAhg −1 at 0.30 Ag -1 ), and long cycling life time (254 mAhg −1 at 0.10 Ag -1 , more than 500 discharge/charge cycles). High specific capacities of 258 and 158 mAhg −1 are obtained at current densities of 0.10 and 3.00 Ag -1 , respectively. The deep discharge capability of the material offers an average voltage below 1.0 V (vs metal Li), which is lower than that of pristine Li 4 Ti 5 O 12 (1.55 V).

Rechargeable Al-ion batteries have attracted great interest due to their advantages in high anode capacity, high safety, etc. However, conventional Al foil negative electrode has critical problems in corrosion and pulverization. Here, we propose a novel Cu-Al composite, which is prepared by a facile electrochemical plating approach, as the negative electrode for addressing above challenges. Remarkably, the plated Cu foil negative electrode delivers excellent stability and long cycle life compared with the Al foil negative electrode, although its thickness and areal mass density are only 30% and ∼76% of that of the Al foil negative electrode, respectively. The essential pulverization problem in bare Al negative electrode would be dramatically reduced attributing to excellent corrosion resistance of Cu foil. Besides, the plated Al is still attached to the Cu foil during repeated charge-discharge processes, resulting in a nearly 100% Coulombic efficiency even after long-term cycling. More importantly, the plated Cu foil negative electrode is convenient for the large-scale practical applications. In view of our results, this work opens an effective approach for configuring low-cost, high energy density, long cycle life and scalable negative electrode of Al-ion batteries.

Eco-friendly carbon-based anodes are highly attractive for use as anode materials in lithium-ion batteries because of their accessibility, high conductivity, and satisfactory storage capacity. However, to date, the carbon anodes reported in literature exhibit low capacity, poor cycling stability, and cannot meet the current increasing demands for materials that possess high energy density . Herein, highly nitrogen-doped expandable carbon-based anodes are developed using the zeolitic imidazolate frameworks (ZIFs) ZIF-67 and ZIF-8 as self-sacrificial templates. Compared with pure carbon anodes, such as graphene oxide (GO) and carbon nanotubes (CNTs), the expandable N-doped with small size CNTs decorated GO (NC-GO) and CNTs (NC-CNTs) anodes developed in this work exhibit gradually increasing reversible specific capacities, as well as high capacities of 790 and 800 mA h g −1 , respectively, which can be sustained even after 500 cycles at 100 mA g −1 . Moreover, the anodes show ultralong cycling lives with extremely low capacity loss rates in each cycle of 0.0042% for NC-GO over 7000 cycles and 0.0035% for NC-CNTs over 10,000 cycles, which are superior to those in the current literature. This work details a new vision and direction for the development of high-capacity ultralong cycling life carbon-based anodes for use in next generation rechargeable energy storage systems .

Among the families of modern energy storage devices, the potassium-ion batteries (PIBs) are emerging as a shining star with desired high energy density and interesting commercial application prospect. However, they still encounter the big question with intrinsically bad cycle stability, especially under high-temperature working conditions. In this work, we report the progress on exploring high-temperature PIBs with ultrahigh stability, based on metal organic framework-5 (MOF-5) as anode materials. At the fixed working temperature of 62.5 °C, the as-constructed PIBs have initial discharge and charge specific capacities of respective ∼ 1183 and 210 mA h g −1 at a current density of 200 mA g −1 , and hold a specific capacity of 160 mA h g −1 with a low decay of 0.15% per cycle over 150 cycles. Even at a high current density of 500 mA g −1 , they deliver a reversible specific capacity of 56 mA h g −1 with a tiny decay of 0.018% per cycle over 3000 cycles, which is the state-of-the-art one among those of high-temperature PIBs ever reported. The energy storage mechanism based on C O bond as the redox center is proposed.

Rechargeable aluminum-ion batteries (AIBs) are promising candidates for energy storage because of their low cost, high safety, and high-power density owing to the three-electron redox reaction . However, the applications of AIBs are hindered by their limited lifetime and practically achievable energy density . Herein, we present a novel Fe-doped Nickel selenide (Fe-NiSe) nanoflake cathode material , derived from a Ni–Fe layered double hydroxide , affording a long cycle life and high energy density . Synergism between the ultrafine nanostructure and Fe doping provided shorter ion diffusion pathways and created multiple active sites in the cathode. As a result, the prepared Fe–NiSe battery achieved an outstanding energy density of 402.5 W h kg −1 and an ultra-long lifespan of 13,500 cycles with a capacity decay of only 0.0026% per cycle. Furthermore, based on the mass of the entire pouch-type cell, the fabricated AIB delivered an energy density of 101.2 W h kg −1 . This work paves the way for serviceable high-energy density AIBs.

Serious solvation effect of zinc ions has been considered as the cause of the severe side reactions (hydrogen evolution, passivation, dendrites, and etc.) of aqueous zinc metal batteries. Even though the regulation of cationic solvation structure has been widely studied, effects of the anionic solvation structures on the zinc metal were rarely examined. Herein, co-reconstruction of anionic and cationic solvation structures was realized through constructing a new multi-component electrolyte (Zn(BF 4 ) 2 -glycerol-boric acid-chitosan-polyacrylamide, simplified as ZGBCP), which incorporates double crosslinking network via the esterification, protonation and polymerization reactions, thereby combining multiple advantages of ‘liquid-like’ high conductivity, ‘gel-like’ robust interface, and ‘solid-like’ high Zn 2+ transfer number. Based on the ZGBCP electrolyte, the Zn anodes achieve record-low polarization and stable cycling. Furthermore, the ZGBCP electrolyte renders the AZMBs ultrawide working temperature (−50 °C ~ +100 °C) and ultralong cycle life (30000 cycles), which further validates the feasibility of the dual solvation structure strategy and provides a innovative perspective for the development of high-performance AZMBs.

Supercapacitors are widely used in power reserves and portable power devices because of their rapid charge and discharge rates and excellent cycle performance. Carbon materials have the characteristics of large specific surface areas, excellent electrical conductivity, good chemical stability, and low price, so they are very attractive as electrode materials for supercapacitors. In recent decades, the electrochemical properties of supercapacitors based on porous carbon have attracted much interest. Through the design of supercapacitors of reasonable appearance, pore shape, and surface characteristics, their electrochemical performance has been significantly improved. Herein, a simple and easy process is developed to synthesize a new kind of porous carbon materials with N,O-doping. The constructed supercapacitor with the as-prepared carbon material exhibits excellent capacitance performance and rapid charge and discharge rates (<1 s, 20 A/g, two-electrode cell), ultralong cycle life (>89,000 cycles, 10 A/g), large specific capacitance (276.5 F/g, 0.5 A/g), and excellent energy density (38.4 W/h/kg). Its superior properties make it one of the best candidate electrode materials for supercapacitors derived from ligands. Its excellent supercapacitor performance is probably related to its high ion-accessible specific surface area, hierarchical regular pore structure, and well N,O-doping on the surface of the carbon composite. This study provides a feasible strategy for the development of high-performance supercapacitors suitable for commercial applications.

Recently, spinel high-entropy oxide (HEO) anode materials have garnered extensive attention for high-energy lithium-ion batteries due to their high specific capacity. Many studies have explored its energy storage mechanism, but few have paid attention to its characteristics in long cycle life. In this work, the whole life cycling performance of (FeCoNiCrMn)-HEO is presented and investigated for the first time. Distinct capacity trends are studied to divide the cycling life into three stages: activation, upgradation, and degradation. Ex situ morphological characterizations are conducted to reveal that the driving force of stage change is continuous particle fragmentation. As a result, refined particles promote conversion reaction reversibility and induce extra interfacial capacity, achieving 2831 mAh g −1 at 825 cycles. Density functional theory (DFT) calculations provide a deeper insight into the high entropy effect on the ultra-high extra interfacial capacity. However, continuous refinement brings about huge electrolyte interface-derived layers, which are also responsible for pre-decay and post-collapse. The view of the evolution of the lithium storage mechanism is explicitly presented and experimentally verified by high-energy ball milling and fluorinated vinyl carbonate (FEC). These above results can give practical solutions to design high specific capacity and long-life cycle stability HEO anode in the future.

Because of the high safety, abundant resource and low cost of sodium ion batteries (SIBs), lithium ion batteries (LIBs) will be replaced by SIBs with the ever-increasing market demand for high performance and low cost energy storage battery system. However, the short cycle life and poor rate performance for current SIBs restrict their further application. Cathode materials are the most important component for the development of SIBs, which have an unparalleled effect on enhancing the electrochemical performance of SIBs. Herein, a high electrochemical performance O3-type NaMn 2/3 Co 1/6 Ni 1/6 O 2 is synthesized by hydrothermal method and high-temperature annealing. The as-prepared sample shows the uniform spherical morphology and exhibits a specific capacity of 153.6 mAh g −1 with high capacity retention of 81.7% after 100 cycles and the coulombic efficiency of 98%. Moreover, the sample also exhibits excellent rate performance and the reversible capacity is 91.6 mAh g −1 at 1 C. The remarkably enhancing electrochemical performances make it be considered as a promising cathode active material of SIBs.

Using high-capacity alloy anodes can grandly advance potassium-ion batteries. However, one common issue plaguing these anodes is the loss of active K + ions associated with persistent side reactions on unstable electrode-electrolyte interfaces, resulting in low initial Coulombic efficiency (ICE) and shortened cycling life. Herein, we first explore the potential of a solution-based potassiation reagent (potassium-biphenyl in dimethoxyethane, K-Bp/DME) for chemical prepotassiation. With a low redox potential of 0.45 V vs . K + /K, the K-Bp/DME solution can readily pre-storing K + ions into various alloy-type anodes by a simple immersion operation in a few minutes. Taking nanostructured Bi/P/CNT composite as an example, we demonstrate that the K-Bp/DME prepotassiation simultaneously enables the notable ICE improvement (from 51.9% to 96.2%) and long-life cycling (running 700 cycles at 1.5 A g −1 with a tiny capacity attenuation rate of 0.031% per cycle) by forming a KF-rich SEI film. Furthermore, the full cell assembled by coupling the prepotassiated Bi/P/CNT anode with a potassium Prussian blue cathode delivers a desirable ICE of 88.6% and superior capacity retention of 75.3% after 450 cycles at 0.3 A g −1 . Besides, this prepotassiation method is also successfully extended to other anodes (Sb and Sn), indicating its general applicability.

Rechargeable sodium-chlorine (Na-Cl 2 ) batteries show high theoretical specific energy density and excellent adaptability for extreme environmental applications. However, the reported cycle life is mostly less than 500 cycles, and the understanding of battery failure mechanisms is quite limited. In this work, we demonstrate that the substantially increased voltage polarization plays a critical role in the battery failure. Typically, the passivation on the porous cathode caused by the deposition of insulated sodium chloride (NaCl) is a crucial factor, significantly influencing the three-phase chlorine (NaCl/Na + , Cl - /Cl 2 ) conversion kinetics. Here, a self-depassivation strategy enabled by iodine anion (I - )-tuned NaCl deposition was implemented to enhance the chlorine reversibility. The nucleation and growth of NaCl crystals are well balanced through strong coordination of the NaI deposition-dissolution process, achieving depassivation on the cathode and improving the reoxidation efficiency of solid NaCl. Consequently, the resultant Na-Cl 2 battery delivers a super-long cycle life up to 2000 cycles.
