Crystallographic Customization of Zinc Anode for High Performance Aqueous Metal Batteries

Nano Letters (2025)

Jibo Zhang Qingyuan Zhao Xin Wei Aijun Li Hai Xu

Aqueous zinc metal batteries (AZMBs) are an energy storage system that is expected to replace traditional lithium batteries. However, the practical application of AZMBs is hampered by some inherent drawbacks. Herein, an amino acid additive with a screening property is introduced. The additives effectively erode Zn(002) by binding to a specific zinc crystallographic plane, achieving an ordered layered three-dimensional structure anode, and the shielding effect of additives can inhibit the activated H2O and induce uniform Zn deposition. Accordingly, a stable long-term cycling for 3750 h at 1 mA cm–2 and an ultrahigh Coulombic efficiency (99.7%) are obtained. The cell also achieves a cycling life of nearly 1000 h, even at 10 mA cm–2 (cumulative capacity over 5 Ah cm–2). Moreover, a capacity retention of 80% after 1000 cycles and a superior rate are exhibited for Zn//V2O5 cells. The work provides theoretical support for achieving highly reversible Zn anode.

Noncovalent Interactions Engineering Construct the Fast-Kinetics Organic Cathode for Room/Low-Temperature Aqueous Zinc-Ion Battery

SSRN Electronic Journal (2022)

Ruanye Zhang Hai Xu Derong Luo Jiaxiang Chi Zengjie Fan

Electroactive organic electrode materials are serving to be an attracting candidate for aqueous Zn ion batteries (AZIBs). However, the insufficient electrical conductivity and intrinsic soluble trait of organic molecules restrict its application. Here, a carbonyl compound, dibenzo[b,i]thian threne-5,7,12,14-tetraone (DTT) is wrapped by reduced graphene oxide (r-GO) with noncovalent interactions to obtain DTT@r-GO hybrid electrodes for AZIBs. Benefiting from the π-π coupling, the composite electrode delivers higher surface area, enhanced the electron/ion transportation and stable structure, which exhibits superior rate performance (259.1 mAh g-1 at 0.1 Ag-1and 117.7 mAh g-1 at 10 A g-1) and considerable calendar life (4000 cycles with 100% capacity retention at 10 A g-1). Electrochemical testing and ex-situ analysis prove C=O can act as a strong electron donor together with co-accommodation of Zn2+/H+, theoretical calculation confirm the favorable two-step Zn storage configuration during charge storage process. Furthermore, this AZIBs can steadily power to electronic devices at -50 ℃, as well as retain a high reversible capacity of 199.5 mAh g-1 at 50 mA g-1 and 100% capacity retention after 3700 cycles at -20 ℃. The work is believed to broaden the insight of noncovalent interactions and inspire the organic electrochemical materials.

Outstanding Lithium Storage Performance of a Copper‐Coordinated Metal‐Covalent Organic Framework as Anode Material for Lithium‐Ion Batteries

Energy & environment materials (2024)

Derong Luo Huizi Zhao Feng Liu Hai Xu Xiaoyu Dong

Metal‐covalent organic frameworks (MCOF) as a bridge between covalent organic framework (COF) and metal organic framework (MOF) possess the characteristics of open metal sites, structure stability, crystallinity, tunability as well as porosity, but still in its infancy. In this work, a covalent organic framework DT‐COF with a keto‐enamine structure synthesized from the condensation of 3,3′‐dihydroxybiphenyl diamine (DHBD) and triformylphloroglucinol (TFP) was coordinated with Cu 2+ by a simple post‐modification method to a obtain a copper‐coordinated metal‐covalent organic framework of Cu‐DT COF. The isomerization from a keto‐enamine structure of DT‐COF to a enol‐imine structure of Cu‐DT COF is induced due to the coordination interaction of Cu 2+ . The structure change of Cu‐DT COF induces the change of the electron distribution in the Cu‐DT COF, which greatly promotes the activation and deep Li‐storage behavior of the COF skeleton. As anode material for lithium‐ion batteries (LIBs), Cu‐DT COF exhibits greatly improved electrochemical performance, retaining the specific capacities of 760 mAh g −1 after 200 cycles and 505 mAh g −1 after 500 cycles at a current density of 0.5 A g −1 . The preliminary lithium storage mechanism studies indicate that Cu 2+ is also involved in the lithium storage process. A possible mechanism for Cu‐DT COF was proposed on the basis of FT‐IR, XPS, EPR characterization and electrochemical analysis. This work enlightens a novel strategy to improve the energy storage performance of COF and promotes the application of COF and MCOF in LIBs.

Ionic Liquid‐Based Electrolyte with Multiple Hydrogen Bonding Network Enabling High‐Voltage Stable Proton Batteries Across Wide Temperature Range

Advanced Science (2025)

Xiaoyu Dong Zhiwei Li Hai Xu Zhiyuan Wu Fanhao Meng

Proton batteries are strong contender for next-generation energy storage due to their high safety and rapid response. However, the narrow electrochemical window of acidic aqueous electrolytes limits their energy density and stability. Here, an ionic liquid (IL)-based electrolyte (EMImOTf-H3PO4) containing H3PO4 in polar IL solvent 1-ethyl-3-methylimidazolium trifluoromethanesulfonate (EMImOTf) is developed for stable high-voltage energy storage. H3PO4 serving as a proton source interacts with both EMIm+ and OTf-, forming an intricate hydrogen bonding network that effectively prevents electrolyte decomposition at high voltage. The half-cell in EMImOTf-H3PO4 electrolyte and pre-protonated vanadium hexacyanoferrate (H-VHCF) cathode demonstrates a 126% improvement in Coulombic efficiency over aqueous electrolytes at a current density of 1 A g-1. The fabricated PTCDA/MXene//EMImOTf-H3PO4//H-VHCF full battery achieves an operating voltage of 2 V at room temperature, surpassing currently reported values for proton batteries. After 30 000 cycles at 5 A g-1, the battery retains 86.1% of its initial capacity. It delivers an energy density of 87.5 Wh kg-1 and a power density of 30.6 kW kg-1 at room temperature, and can maintain stable operation across a temperature range of 110 °C (-60 ∼ 50 °C). These findings present new possibilities for proton batteries in all-weather grid-scale energy storage applications.

Synergistic Ion Sieve and Solvation Regulation by Recyclable Clay-Based Electrolyte Membrane for Stable Zn-Iodine Battery

ACS Nano (2023)

Hai Xu Ruanye Zhang Derong Luo Jiuqing Wang Hui Dou

The high dissolution of polyiodides and unstable interface at the anode/electrolyte severely restrict the practical applications of rechargeable aqueous Zn-iodine batteries. Herein, we develop a zinc ion-based montmorillonite (ZMT) electrolyte membrane for synergizing ion sieve and solvation regulation to achieve highly stable Zn-iodine batteries. The rich M-O band and special cation-selective transport channel in ZMT locally tailor the solvation sheath around Zn2+ and therefore achieve high transference number (t+ = 0.72), benefiting for uniform and reversible deposition/stripping of Zn. Meanwhile, the mechanisms for three-step polyiodide generation and shuttle-induced Zn corrosion are highlighted by in situ characterization techniques. It is confirmed that the strong chemical adsorption between O atoms in ZMT and polyiodides species is the key to effectively inhibit the shuffle effect and side reactions. Consequently, the ZMT-based Zn-iodine battery delivers a high capacity of 0.45 mAh cm-2 at 1 mA cm-2 with a much improved Coulombic efficiency of 99.5% and outstanding capacity retention of 95% after 13 500 cycles at 10 mA cm-2. Moreover, owing to its high durability and chemical inertness and structural stability, ZMT-based electrolyte membranes can be recycled and applied in double-sided pouch cells, delivering a high areal capacity of 2.4 mAh cm-2 at 1 mA cm-2.
