In Situ Anchoring Ultrafine ZnS Nanodots on 2D MXene Nanosheets for Accelerating Polysulfide Redox and Regulating Li Plating

Advanced Materials (2023)

Chuanliang Wei Baojuan Xi Peng Wang Yazhan Liang Zhengran Wang

Lithium-sulfur (Li-S) battery is a promising energy storage system due to its cost effectiveness and high energy density. However, formation of Li dendrites from Li metal anode and shuttle effect of lithium polysulfides (LiPSs) from S cathode impede its practical application. Herein, ultrafine ZnS nanodots are uniformly grown on 2D MXene nanosheets by a low-temperature (60 °C) hydrothermal method for the first time. Distinctively, the ZnS nanodot-decorated MXene nanosheets (ZnS/MXene) can be easily filtered to be a flexible and freestanding film in several minutes. The ZnS/MXene film can be used as a current collector for Li-metal anode to promote uniform Li deposition due to the superior lithiophilicity of ZnS nanodots. ZnS/MXene powders obtained by freeze drying can be used as separator decorator to address the shuttle effect of LiPSs due to their excellent adsorbability. Theoretical calculation proves that the existence of ZnS nanodots on MXene can obviously improve the adsorption ability of ZnS/MXene with Li+ and LiPSs. Li-S full cells with composite Li-metal anode and modified separator exhibit remarkable rate and cycling performance. Other transition metal sulfides (CdS, CuS, etc.) can be also grown on 2D MXene nanosheets by the low-temperature hydrothermal strategy.

Ligand engineering regulation toward Zn ions and Zn substrate for all‐climate Zn metal batteries

Angewandte Chemie International Edition (2025)

Zhengchunyu Zhang Tianyang Xu Kun Xu Zihan Jiang Di Sun

The regulation of artificial interphase for advanced Zn anode is an effective solution to achieve superior electrochemical performance for aqueous batteries. However, the deployment of atomically precise architectures and ligand engineering to achieve functionalization-oriented regulatory screening is lacking, which is hindered by higher requirements for synthetic chemistry and structural chemistry. Herein, we have first performed ligand engineering which selected zinc ion trapping ligands (-CH3) based on the coordination effect, and zinc substrate binding ligands (-N=N-xC6H5) based on the electrostatic interaction. Correspondingly, octa nuclear Zn(II)-Siloxane-PhPz/BiPhPz/TriPhPz Cluster (OZSPC/OZSBPC/OZSTPC) are accurately synthesized, and OZSBPC is verified to serve as the most suitable artificial interphase via balancing the interactions with both Zn2+ and Zn substrate ("Zn-Zn effect"). Consequently, at -30 °C, the assembled OZSBPC-Zn symmetric cells run for 3000 h and the assembled full cells with OZSBPC-Zn anode could be stable for 10,000 cycles. The pouch cells using OZSBPC-Zn anode deliver a reversible capacity of ~1.2 Ah and the energy density of 41 Wh kgtotal-1 with excellent cycling performance. The successful structural design of OZSBPC explores a novel well-defined structural design concept as one criterion for artificial interface as well as motivates batteries systems to meet the requirements of industrialization.

Enhanced Capacity and Rate Capability of Nitrogen/Oxygen Dual‐Doped Hard Carbon in Capacitive Potassium‐Ion Storage

Advanced Materials (2017)

Jinlin Yang Zhicheng Ju Yong Jiang Zheng Xing Baojuan Xi

The intercalation of potassium ions into graphite is demonstrated to be feasible, while the electrochemical performance of potassium-ion batteries (KIBs) remains unsatisfying. More effort is needed to improve the specific capacity while maintaining a superior rate capability. As an attempt, nitrogen/oxygen dual-doped hierarchical porous hard carbon (NOHPHC) is introduced as the anode in KIBs by carbonizing and acidizing the NH2 -MIL-101(Al) precursor. Specifically, the NOHPHC electrode delivers high reversible capacities of 365 and 118 mA h g-1 at 25 and 3000 mA g-1 , respectively. The capacity retention reaches 69.5% at 1050 mA g-1 for 1100 cycles. The reasons for the enhanced electrochemical performance, such as the high capacity, good cycling stability, and superior rate capability, are analyzed qualitatively and quantitatively. Quantitative analysis reveals that mixed mechanisms, including capacitance and diffusion, account for the K-ion storage, in which the capacitance plays a more important role. Specifically, the enhanced interlayer spacing (0.39 nm) enables the intercalation of large K ions, while the high specific surface area of ≈1030 m2 g-1 and the dual-heteroatom doping (N and O) are conducive to the reversible adsorption of K ions.

Dual‐Functional NbN Ultrafine Nanocrystals Enabling Kinetically Boosted Lithium–Sulfur Batteries

Advanced Functional Materials (2022)

Nianxiang Shi Baojuan Xi Jie Liu Zhengchunyu Zhang Ning Song

Abstract Herein, NbN nanocrystals immobilized on N‐doped carbon nanosheets to functionalize a polypropylene (PP) membrane (NbN@NC/PP) with a thin coating of only 4 µm are designed and synthesized. The functional modifier layer allows for sulfur‐involved transformations and also lithium plating behaviors. On the one hand, the sulfur cell with NbN@NC/PP separator exhibits excellent cycling stability and rate capacity. The good electrochemical performance partially results from the strong chemical interactions between NbN and lithium polysulfides via the formation of NbS and NLi bonds, which is proven by the first‐principles calculations and X‐ray photoelectron spectroscopy analyses. The formation of tiny nanoscrystals (<2 nm) and clusters tends to maximize the surface of NbN to interact with polysulfides and enable the effective catalysis over the sulfur‐involved reactions. The higher exchange current density and Li + diffusion coefficient of NbN@NC/PP cells experimentally verify that the introduction of NbN indeed catalytically accelerates the reaction kinetics. On the other hand, the performance of Li//Li symmetric cells demonstrates that the NbN@NC modifier layer can well induce homogeneous lithium deposition. This work confirms the application potential of NbN in lithium–sulfur batteries and encourages the exploration of prospective nitrides to engineer high performance next‐generation batteries.

WSe₂ Flakelets on N‐Doped Graphene for Accelerating Polysulfide Redox and Regulating Li Plating

Angewandte Chemie International Edition (2021)

Peng Wang Fanghan Sun Shenglin Xiong Zhengchunyu Zhang Bin Duan

The practical application of lithium-sulfur batteries is still limited by the lithium polysulfides (LiPSs) shuttling effect on the S cathode and uncontrollable Li-dendrite growth on the Li anode. Herein, elaborately designed WSe2 flakelets immobilized on N-doped graphene (WSe2 /NG) with abundant active sites are employed to be a dual-functional host for satisfying both the S cathode and Li anode synchronously. On the S cathode, the WSe2 /NG with a strong interaction towards LiPSs can act as a redox accelerator to promote the bidirectional conversion of LiPSs. On the Li anode, the WSe2 /NG with excellent lithiophilic features can regulate the uniform Li plating/stripping to mitigate the growth of Li dendrite. Taking advantage of these merits, the assembled Li-S full batteries exhibit remarkable rate performance and stable cycling stability even at a higher sulfur loading of 10.5 mg cm-2 with a negative to positive electrode capacity (N/P) ratio of 1.4 : 1.

Highly Reversible Zinc Metal Anodes Enabled by Solvation Structure and Interface Chemistry Modulation

Advanced Energy Materials (2023)

Xiao Wang Kaiqiang Feng Bingyan Sang Guijin Li Zhengchunyu Zhang

Abstract Aqueous Zn−ion batteries (AZIBs) promise appealing advantages including safety, affordability, and high volumetric energy density. However, rampant parasitic reactions and dendrite growth result in inadequate Zn reversibility. Here, a biocompatible additive, L‐asparagine (Asp), in a low‐cost aqueous electrolyte, is introduced to address these concerns. Combining substantive verification tests and theoretical calculations, it is demonstrated that an Asp‐containing ZnSO 4 electrolyte can create a robust nanostructured solid‐electrolyte interface (SEI) by simultaneously modulating the Zn 2+ solvation structure and optimizing the metal‐molecule interface, which enables dense Zn deposition. The optimized electrolyte supports excellent Zn reversibility by achieving dendrite‐free Zn plating/stripping over 240 h at a high Zn utilization of 85.5% in the symmetrical cell and an average 99.6% Coulombic efficiency for over 1600 cycles in the asymmetrical cell. Adequate full‐cell performance is demonstrated with a poly(3,4‐ethylenedioxythiophene) intercalated vanadium oxide (PEDOT‐V 2 O 5 ) cathode, which delivers a high areal capacity of 4.62 mAh cm −2 and holds 84.4% capacity retention over 200 cycles under practical conditions with an ultrathin Zn anode (20 µm) and a low negative/positive capacity ratio (≈2.4). This electrolyte engineering strategy provides new insights into regulating the anode/electrolyte interfacial chemistries toward high‐performance AZIBs.

Layer-by-Layer Stacked (NH₄)₂V₄O₉·0.5H₂O Nanosheet Assemblies with Intercalation Pseudocapacitance for High Rate Aqueous Zinc Ion Storage

ACS Applied Energy Materials (2020)

Ruchao Wei Xiao Wang Baojuan Xi Zhenyu Feng Haibo Li

Rechargeable aqueous zinc-ion batteries have become an emerging candidate for large-scale energy storage due to their low cost and high safety, the lack of suitable advanced cathode materials with high specific capacity, and desirable long cycle life, as well as the elusive intercalation mechanism, which hinders their potential applications. Herein, a layer-by-layer stacked (NH4)2V4O9·0.5H2O nanosheet assembly is engineered and prepared by a mild hydrothermal protocol, demonstrating ultrahigh rate capability (101 mAh g–1 at 15 A g–1), a high discharge capacity of 374.3 mAh g–1 at 0.2 A g–1, and desirable cycling stability at high rates (84% after 1000 cycles at 5 A g–1). Benefiting from the stable and stacked layer structure, the zinc-ion charge storage is revealed to be boosted by intercalation pseudocapacitance behavior with the capacitive contribution as high as 78.1% of the total capacity at 1 mV s–1. The ex situ analyses confirm the good reversibility with the continuous cointercalation reaction mechanism of H+ and Zn2+ as well as water molecules. This study provides a feasible protocol to engineer the cathode material with superior Zn-storage performance, providing inspiration for developing suitable cathodes beyond zinc-ion batteries.
