Aqueous zinc-ion batteries (ZIBs) features prominently in virtue of their high theoretical capacity, reliable security, eco-friendliness and excellent rate capability. However, conventional zinc anodes suffer from the poor reversibility and unsatisfactory cycle durability due to the serious dendrite growth and parasitic side reactions, becoming a huge technological challenge to their commercial applications. Herein, a redox-active π-conjugated molecule, 2,2′,2’’-(benzene-1,3,5-triyl)tris (1H-naphtho [2,3- d ]imidazole-4,9-dione) (BTHI), is designed as substitute for Zn-metal anode. The BTHI electrode shows a high reversible capacity of 342 mAh g −1 at 0.1 A g −1 (approaching its theoretical capacity of 362 mAh g −1 , 9 electrons transfer), along with rapid kinetics for charge storage. Both ex-situ spectroscopy characterizations and electrochemical experiments demonstrate reversible H + /Zn 2+ co-insertion/extraction behaviors in the BTHI electrode. The density-functional theory (DFT) simulation results further indicate that H + insertion is thermodynamically favored over Zn 2+ uptake and reveal that protons are first inserted into six carbonyl groups , followed by the C N bonds of three imidazole subunits. By pairing the BTHI anode with copper hexacyanoferrate (CuHCF) cathode, a Zn-metal-free BTHI//CuHCF full cell is assembled, which delivers a record high capacity (315 mAh g −1 at 1 A g −1 ), outstanding rate performance (207 mAh g −1 at 10 A g −1 ), and remarkable cycling durability (71.9 % capacity retention rate after 1000 cycles at 10 A g −1 ).

Polyoxometalates (POMs) are widely thought as promising choices for sodium-ion batteries (SIBs) because of their refined molecular structures and excellent reversible multielectron charge-discharge behaviors. Nevertheless, the POMs anion clusters could dissolve in the electrolyte when attacked by solvent molecules, thus reducing active sites and affecting the actual performance of these POMs-based electrodes. Herein, we report the development of a new type of electrode system that produces single-dispersed POMs molecular cluster/polydopamine/reduced graphene oxide composites ({PMo12}/PDA@rGO) through a self-assembly method. PDA acts as the role of “killing two birds with one stone”. It not only works as the linker to promote the formation of stable and uniform monodisperse {PMo12} clusters on the rGO surface, but also prevents the POMs from desorbing and dissolving upon deep cycling test. As a consequence, when used as the anode material for SIBs, the obtained {PMo12}/PDA@rGO exhibits an admirable long-term cycling performance, for instance, it holds a high Na-storage capacity of 277.5 mAh g −1 with an average Coulomb efficiency up to 99.89 % over 2000 cycles at 1 A g −1 . This work offers versatile possibilities for designing POMs-based composites and provides new insight into developing single dispersed POMs for advanced SIBs.

NASICON (NAtrium Super Ionic CONductor)-structured Na 4 MnCr(PO 4 ) 3 has attracted attention as a promising cathode for sodium-ion batteries due to its high operating voltage and specific capacity contributed by multielectron reactions. Unfortunately, its intrinsic low electronic conductivity significantly hinders the release of specific capacity and rate capability, preventing its practical application. Herein, a carbon layer with dual conductive networks connected by chain-like Ketjen black (KB) is built on the surface of Na 4 MnCr(PO 4 ) 3 material. This novel Na 4 MnCr(PO 4 ) 3 /C@KB composite material exhibits improved rate capability of 61.2 mAh g −1 at 2 C compared to 19.5 mAh g −1 of Na 4 MnCr(PO 4 ) 3 /C and high reversible capacity of 88.0 mAh g −1 at 1 C with 73% capacity retention after 100 cycles. The enhanced electrochemical performance can be ascribed to an increase of electronic conductivity enabled by the dual conductive 3D network construction and an adequate infiltration of electrolyte by substantial pores existence in carbon layer. A promising dual conductive network design strategy is demonstrated here for improving the performance of NASICON-structured cathodes.

Liquid metal battery (LMB) has raised extensive interest in the field of large-scale energy storage applications . The Zn-based LMB composed of inexpensive Zn and low-temperature electrolyte have proven to be feasible and promising. However, the low voltage plateau and coulombic efficiency still limit their practical application. Here we demonstrate a simple design Zn-based LMB, which consists of Zn 5 Sn 5 alloy as negative electrode , Bi as positive electrode and ZnCl 2 –LiCl–KCl molten salt with lower zinc chloride content as electrolyte. The battery can stably operate at a low temperature of 375 °C and exhibit a flat and high voltage plateau of 0.8–0.9 V. A high coulombic efficiency of over 96% can be achieved by optimizing the composition of electrolyte. Sn is added to yield a liquid negative electrode, and then the problem of Zn dendrites can be avoided. In addition to Zn, both Sn and Bi participate in the redox reaction , which contributes to a multiple redox reaction mechanism. The Zn-based liquid metal batteries with low temperature and high voltage will be a prospective choice for large-scale energy storage.

Aqueous zinc-iodine (Zn-I 2 ) batteries are promising energy storage devices; however, the conventional single-electron reaction potential and energy density of iodine cathode are inadequate for practical applications. Activation of high-valence iodine cathode reactions has evoked a compelling direction to developing high-voltage zinc-iodine batteries. Herein, ethylene glycol (EG) is proposed as a co-solvent in a water-in-deep eutectic solvent (WiDES) electrolyte, enabling significant utilization of two-electron-transfer I + /I 0 /I − reactions and facilitating an additional reversibility of Cl 0 /Cl − redox reaction. Spectroscopic characterizations and calculations analyses reveal that EG integrates into the Zn 2+ solvation structure as a hydrogen-bond donor, competitively binding O atoms in H 2 O, which triggers a transition from water-rich to water-poor clusters of Zn 2+ , effectively disrupting the H 2 O hydrogen-bond network. Consequently, the aqueous Zn-I 2 cell achieves an exceptional capacity of 987 mAh g I2 −1 with an energy density of 1278 Wh kg I2 −1 , marking an enhancement of ≈300 mAh g −1 compared to electrolyte devoid of EG, and enhancing the Coulombic efficiency (CE) from 68.2% to 98.7%. Moreover, the pouch cell exhibits 3.72 mAh cm −2 capacity with an energy density of 4.52 mWh cm −2 , exhibiting robust cycling stability. Overall, this work contributes to the further development of high-valence and high-capacity aqueous Zn-I 2 batteries.

Polyanionic cathode materials with robust structural stability and large Ca 2+ diffusion channels have aroused great interest in propelling the development of calcium-ion batteries (CIBs). However, polyanionic cathodes usually exhibit single-electron transfer per unit, rendering limited specific capacity and energy densities. Herein, a new polyanionic Ca x NaV 1.5 Cr 0.5 (PO 4 ) 3 (0 ≤ x ≤ 1.4) cathode is proposed for high-capacity and ultra-stable CIBs by unlocking 1.87-electron transfer per vanadium redox center during Ca ion insertion. The Ca x NaV 1.5 Cr 0.5 (PO 4 ) 3 cathode delivers a reversible calcium storage capacity of 162 mAh g −1 at an average voltage of ≈2.5 V at 10 mA g −1 , featuring a record-high energy density of ≈400 Wh kg −1 . The low volume changes ( ∆V = 1.8%) and fast diffusion kinetics indicate excellent cycling stability of Ca x NaV 1.5 Cr 0.5 (PO 4 ) 3 with capacity retentions of 98.2% and 80.8% over 600 and 5000 cycles, respectively. In Ca metal full cells made from a Ca metal anode and a compatible electrolyte, the Ca x NaV 1.5 Cr 0.5 (PO 4 ) 3 presents a high energy density of 318 Wh kg −1 over 50 cycles, which rivals the state-of-the-art CIB performance. This work sheds new light on the electrochemically activated multielectron redox reactions of polyanionic cathode materials for sustainable CIBs.

Flow battery is a promising energy storage technology for facilitating utilization of renewable resources. While new types of flow batteries have been explored toward high energy density, hampering the power density due to high electrolyte viscosity and sluggish reaction kinetics. Discovery of an aqueous electrolyte with multi-electron transfer reaction is thus favorable for both high energy and power densities due to its multiple charge stored at the same concentration. Both criteria are crucial to improve the flexibility of cell design and widen the application potential. Herein, bismuth is pioneered as negative electrolyte (negolyte) for hybrid flow battery owing to its three-electron reaction and the significantly increased solubility in methanesulfonic acid. In conjunction with cerium electrolyte, a volumetric energy density of 90 Wh L −1 is achieved and simultaneously a high power density of 295 mW cm −2 at 90% state-of-charge is demonstrated using low-cost carbon electrode. Furthermore, a high volumetric capacity of 120 Ah L −1 is reached via adopting graphite felt, which is 100% of the theoretical specific capacity of 1.5 M bismuth negolyte.

In spite of the recent rapid progress of organic cathode materials for aqueous rechargeable zinc batteries (ARZBs), there are still many challenges such as unaffordable synthesis, unsatisfactory electrochemical performance, and unclear mechanisms in this field. Herein, we report 5,7,12,14-tetraaza-6,13-pentacenequinone (TAPQ) as an easily-synthesized organic cathode material with a novel quinone/pyrazine hybrid structure. Benefitting from the multiple electroactive C=O and C=N bonds, TAPQ possessed a theoretical capacity of 515 mAh g –1 (based on a six-electron reaction) and a practically reversible capacity of 443 mAh g –1 within 0.1–1.6 V vs. Zn 2+ /Zn, both of which set new records for organic cathodes in ARZBs. The H + /Zn 2+ co-insertion mechanism involving H + as the predominant participant was confirmed by detailed investigations including various ex-situ characterizations, electrochemical tests, and DFT calculations. Based on the clear mechanism understanding, a modified voltage range of 0.5–1.6 V was adopted to simultaneously achieve high energy density (270 mAh g –1 × 0.84 V = 227 Wh kg –1 ) and excellent cycling stability (capacity retention of 92% after 250 cycles under 50 mA g –1 , with an average Coulombic efficiency of 99.96%). Furthermore, the evolution mechanism of TAPQ electrode structure during cycling was also carefully studied to reveal the origin of capacity decline. The novel molecular structure, easy synthesis, superior electrochemical performance, and deeper mechanism understanding provide researchers important insights into the further development of organic cathode materials for ARZBs toward practical applications.

Li 2 O-MoO 3 -P 2 O 5 and Li 2 O-MoO 3 -V 2 O 5 -P 2 O 5 amorphous cathode oxides were prepared using a simple melt quenching technique. The discharge-specific capacity of the 2Li 2 O-5MoO 3 -V 2 O 5 -2P 2 O 5 after 100 cycles was 141.43 mAh/g, with a capacity retention rate of 77.27 %, while the discharge-specific capacity of the 2Li 2 O-6MoO 3 -2P 2 O 5 after 100 cycles was 100.52 mAh/g, with a capacity retention rate of 55.78 %, in the voltage range of 1.5–4.2 V and at a current density of 10 mA/g. According to the findings, vanadium pentoxide may help molybdenum-based amorphous cathodes perform better electrochemically. In particular, the Mo 5+ /Mo 4+ transition is inhibited, and the Mo 6+ /Mo 5+ transition is promoted by the presence of the V 5+ /V 4+ transition in the charge/discharge cycle of the Li 2 O-MoO 3 -V 2 O 5 -P 2 O 5 amorphous material, shortening the structural self-regulation process in the electrochemical cycle and significantly increasing cycle stability. The study provided a new idea for investigating novel cathode materials for lithium-ion batteries.

The Mn-based Prussian blue analogs (PBAs) have garnered significant attention due to their high specific capacity, stemming from the unique multi-electron reactions with Na + . However, the structural instability caused by multi-ion insertion impacts the cycle life, thus limiting their further application in aqueous sodium-ion batteries (ASIBs). To address this issue, this work employed an in situ epitaxial solvent deposition method to homogeneously grow Ni hexacyanoferrate (NiHCF) on the surface of MnPBA, which can effectively overcome the de-intercalation instability. The resulting heterostructured MnPBA@NiHCF integrates the multiple redox-active centers of MnPBA with the confinement ability of the outer NiHCF layer, thereby maintaining overall structural stability. As a cathode material for ASIBs, MnPBA@NiHCF achieves a reversible specific capacity of 66.2 mAh/g after 200 cycles at 1 A/g, significantly outperforming the single-component MnPBA and NiHCF, respectively. Moreover, it demonstrates ultralong cycling stability with only 0.0002 % capacity fade per cycle over 20,000 cycles at 10 A/g. Extensive kinetic analyses further confirm its superior Na + diffusion behaviors with disclosed redox mechanism through the comprehensive in situ Raman and ex situ analysis. A full cell built with a polyimide (PI) anode achieved an energy density of up to 59.9 Wh kg −1 , displaying a power output of 1200.4 W kg −1 and exceptional cycle stability. This work provides innovative insights for developing stable PBA cathodes for ASIB applications.

The sodium super ion conductor (NASICON) structure materials are essential for sodium-ion batteries (SIBs) due to their robust crystal structure, excellent ionic conductivity, and flexibility to regulate element and valence. However, the poor electronic conductivity and inferior energy density caused by the nature of these materials have always been obstacles to commercialization. Herein, using yeast as a template to derive NASICON structure Na3MnTi(PO4)3 (NMTP) materials (noted as Yeast@NMTP/C) is presented. The Yeast@NMTP/C material retains the microsphere morphology of the yeast template and not only controls the particle size (around 2 μm) to shorten the Na+ diffusion pathways but also improves the electronic conductivity to optimize the electrochemical kinetics. The Yeast@NMTP/C cathode delivers reversible multielectron redox reactions including Ti4+/3+, Mn3+/2+, and Mn4+/3+ and exhibits a high capacity of 108.5 mAh g–1 with a 79.2% capacity retention after 1000 cycles at a 2C rate. The sodium storage mechanism of Yeast@NMTP/C reveals that the addition of Ti4+/3+ redox plays a key role in improving the Na+ diffusion kinetics, and both solid-solution and two-phase reactions take place during the desodiation and sodiation process. Additionally, the high-rate and long-span cycle performance of Yeast@NMTP/C at 10C is ascribed to contribute to pseudocapacitance.
