  • boosting Zinc Ion intercalatIon in hydrated mos2 nanosheets toward substantially improved performance
    Energy Storage Materials, 2021
    Co-Authors: Huanyan Liu, Jiangan Wang, Chunguang Wei, Wei Hua, Zongyuan You, Zhidong Hou, Junchang Yang, Feiyu Kang
    Abstract:

    Abstract Rechargeable aqueous Zinc-Ion batteries hold great prospects in grid-level energy storage due to their virtues of good safety, low cost and eco-friendliness. However, the sluggish intercalatIon kinetics of divalent Zn2+ makes the exploratIon of a suitable Zn2+-host cathode being a formidable challenge. In this work, we unveil the crucial role of crystal water on boosting the Zn2+ intercalatIon kinetics of layered MoS2 host. The crystal water molecules could functIon as structural pillars to enlarge the interlayer distance of MoS2 and improve the surface hydrophilicity. Notably, a substantially-enhanced Zn2+ intercalatIon kinetics is realized by accelerating the charge-transfer transportatIon and Zn2+ diffusivity. Consequently, the hydrated MoS2 nanosheets enable efficacious Zn2+ insertIon/extractIon to achieve a high specific capacity of 182 mAh g−1 at 0.1 A g−1 and superior rate/cycling performance. The present study will enlighten the water implantatIon strategy to engineering hydrated cathode materials toward high-performance aqueous batteries.

    Electrochimica Acta, 2019
    Co-Authors: Liubing Dong, Chengjun Xu, Zhuang Kang, Baozheng Jiang, Yongfeng Huang, Xianli Wang, Feiyu Kang
    Abstract:

    Abstract Rechargeable Zinc Ion battery is considered as a very promising energy storage system due to its high safety, low cost, and environmentally friendliness. Vanadium oxides with high capacity, good rate performance, and excellent cycle life are important cathode materials for Zinc Ion batteries. Herein, V10O24.12H2O(VOH) with large interlayer spacing and high valence state is prepared by a facile hydrothermal method and used as the cathode material in Zinc Ion battery. The Zn/VOH battery delivers a capacity of 327 mAh g−1 at 0.1 A g−1, and exhibit excellent cycling performance with high retentIon capacity (115 mAh g−1) after 3000 cycles at 1 A g−1. Zinc Ion and proton insertIon mechanism is proposed by exploring the evolutIons of the phase and morphology. Zinc Ion and proton insertIon mechanism is verified by different Zinc salt electrolytes. The reactIon kinetics tests of Zn/VOH (galvanostatic intermittent titratIon technique (GITT) and electrochemical impedance spectroscopy (EIS)) indicate that the Zinc Ion insertIon process has fast reactIon kinetics and the proton insertIon process slows down the reactIon kinetics. The research of Zn/VOH system expand the cathode material of Zinc Ion battery and enrich the comprehensIon of Zinc Ion battery reactIon mechanism.

    Journal of Materials Chemistry, 2019
    Co-Authors: Jinjin Wang, Jiangan Wang, Huanyan Liu, Chunguang Wei, Feiyu Kang
    Abstract:

    Rechargeable Zinc-Ion batteries based on Zn/MnO2 in neutral aqueous electrolytes are promising for grid-scale energy storage applicatIons owing to their favorable merits of high safety, low cost and environmental benignity. However, MnO2 cathodes are subjected to the challenging issues of poor cyclability and low rate capability. Herein, we report a facile chemical method for the preparatIon of mesoporous MnO2 flower-like nanospheres with the layered framework stabilized by hydrated Zn2+ pillars. The MnO2 cathode could deliver a reversible specific capacity of 358 mA h g−1 at 0.3 A g−1 after 100 cycles, a high rate capacity of 124 mA h g−1 at 3.0 A g−1, and excellent operating stability over 2000 cycles. Structural and morphological investigatIons demonstrate an energy storage mechanism of co-insertIon/extractIon of H+ and Zn2+ accompanied by depositIon/dissolutIon of Zinc sulfate hydroxide hydrate flakes on the electrode surface. The superior electrochemical performance makes the Zinc Ion stabilized MnO2 promising for high capacity and long lifespan Zinc-Ion batteries.

    Energy Storage Materials, 2018
    Co-Authors: Liubing Dong, Ling Zhao, Wenbao Liu, Junye Cheng, Quanhong Yang, Feiyu Kang
    Abstract:

    Abstract With rapid development of portable electronics and electric vehicles, high-performance energy storage devices are urgently needed; however, the existing energy storage systems often have some deficiency, such as low energy for supercapacitors, security risks for lithium-Ion batteries and poor cycling stability for alkaline Zinc/manganese dioxide batteries. Here we report a novel energy storage system of Zinc-Ion hybrid supercapacitors (ZHSs), in which activated carbon materials, Zn metal and ZnSO4 aqueous solutIon serve as cathode, anode and electrolyte, respectively. Reversible Ion adsorptIon/desorptIon on AC cathode and Zn2+ depositIon/stripping on Zn anode enable the ZHSs to repeatedly and rapidly store/deliver electrical energy, accompanying with a capacity of 121 mAh g−1 (corresponding to an energy of 84 Wh kg−1), a very large power output of 14.9 kW kg−1 and an excellent cycling stability with 91% capacity retentIon over 10000 cycles. The extremely safe, high-rate and ultralong-life ZHSs are believed to provide new optIons for next-generatIon energy storage devices.

  • issues and opportunities facing aqueous Zinc Ion batteries
    Energy and Environmental Science, 2019
    Co-Authors: Boya Tang, Shuquan Liang, Lutong Shan, Jiang Zhou
    Abstract:

    Zinc-Ion batteries built on water-based electrolytes featuring compelling price-points, competitive performance, and enhanced safety represent advanced energy storage chemistry as a promising alternative to current lithium-Ion battery systems. Attempts to develop rechargeable aqueous Zinc-Ion batteries (ZIBs) can be traced to as early as the 1980s; however, since 2015, the research activity in this field has surged throughout the world. Despite the achievements made in exploring electrode materials so far, significant challenges remain at the material level and even on the whole aqueous ZIBs system, leading to the failure of ZIBs to meet commercial requirements. This review aims to discuss how to pave the way for developing aqueous ZIBs. The current research efforts related to aqueous ZIBs electrode materials and electrolytes are summarized, including an analysis of the problems encountered in both cathode/anode materials and electrolyte optimizatIon. Some concerns and feasible solutIons for achieving practical aqueous ZIBs are discussed in detail. We would like to point out that merely improving the electrode materials is not enough; synergistic optimizatIon strategies toward the whole battery system are also deeply needed. Finally, some perspectives are provided on the subsequent optimizatIon design for further research efforts in the aqueous ZIB field.

    Journal of Materials Chemistry, 2019
    Co-Authors: Lutong Shan, Guozhao Fang, Jiang Zhou, Mingming Han, Xinxin Cao, Shuquan Liang
    Abstract:

    Tremendous attentIon has been paid to aqueous Zinc-Ion batteries (ZIBs) with the merits of low cost, safety and environmental benignity. ExploratIon of the Zn2+ Ion storage mechanism is of great significance to the fundamental understanding and future practical applicatIon of advanced aqueous Zn-Ion battery systems. Herein, we have observed the reductIon displacement reactIon mechanism upon Zn2+ insertIon/extractIon into/from the structure of copper pyrovanadate (Cu3(OH)2V2O7·2H2O), i.e., Zn2+ insertIon would drive the reductIon of Cu2+ to metallic Cu0 particles, and also the phase transitIon from Cu3(OH)2V2O7·2H2O to a new phase of Zn0.25V2O5·H2O. As a result, Cu3(OH)2V2O7·2H2O is able to deliver excellent electrochemical performance (e.g., a high discharge capacity of 136 mA h g−1 can be maintained after 3000 repetitive cycles at 10 A g−1).

  • V2O5 Nanospheres with Mixed Vanadium Valences as High Electrochemically Active Aqueous Zinc-Ion Battery Cathode
    SpringerOpen, 2019
    Co-Authors: Fei Liu, Guozhao Fang, Jiang Zhou, Yangsheng Cai, Boya Tang, Zixian Chen, Ziqing Wang, Shuquan Liang
    Abstract:

    Abstract A V4+-V2O5 cathode with mixed vanadium valences was prepared via a novel synthetic method using VOOH as the precursor, and its Zinc-Ion storage performance was evaluated. The products are hollow spheres consisting of nanoflakes. The V4+-V2O5 cathode exhibits a prominent cycling performance, with a specific capacity of 140 mAh g−1 after 1000 cycles at 10 A g−1, and an excellent rate capability. The good electrochemical performance is attributed to the presence of V4+, which leads to higher electrochemical activity, lower polarizatIon, faster Ion diffusIon, and higher electrical conductivity than V2O5 without V4+. This engineering strategy of valence state manipulatIon may pave the way for designing high-performance cathodes for elucidating advanced battery chemistry

  • Recent Advances in Aqueous Zinc-Ion Batteries
    ACS energy letters, 2018
    Co-Authors: Guozhao Fang, Jiang Zhou, Shuquan Liang
    Abstract:

    Although current high-energy-density lithium-Ion batteries (LIBs) have taken over the commercial rechargeable battery market, increasing concerns about limited lithium resources, high cost, and insecurity of organic electrolyte scale-up limit their further development. Rechargeable aqueous Zinc-Ion batteries (ZIBs), an alternative battery chemistry, have paved the way not only for realizing environmentally benign and safe energy storage devices but also for reducing the manufacturing costs of next-generatIon batteries. This Review underscores recent advances in aqueous ZIBs; these include the design of a highly reversible Zn anode, optimizatIon of the electrolyte, and a wide range of cathode materials and their energy storage mechanisms. We also present recent advanced techniques that aim at overcoming the current issues in aqueous ZIB systems. This Review on the future perspectives and research directIons will provide a guide for future aqueous ZIB study.

    Nano Energy, 2018
    Co-Authors: Boya Tang, Guozhao Fang, Jiang Zhou, Liangbing Wang, Yongpeng Lei, Chao Wang, Tianquan Lin, Yan Tang, Shuquan Liang
    Abstract:

    Abstract Rechargeable aqueous Zinc-Ion batteries (ZIBs) are feasible for grid-scale applicatIons due to their unique attributes such as safe, sustainable, and low-cost. However, it is limited by cathode materials, which requires a stable host structure and fast channel for Zinc Ions diffusIon. Here, we develop various kinds of potassium vanadates (K2V8O21, K0.25V2O5, K2V6O16·1.57H2O and KV3O8) as cathodes for aqueous ZIBs. K2V8O21 and K0.25V2O5 with tunnel structure can maintain a stable structure and are conducive to the faster Zinc Ion diffusIon during repeated cycles compared to the layered KV3O8 and K2V6O16·1.57H2O that suffer from structural collapse. The optimal K2V8O21 cathode exhibits excellent Zinc storage performance, with a high capacity of 247 mA h g−1 at 0.3 A g−1 and a good rate at 6 A g−1 as well as excellent cyclic stability up to 300 cycles. The results suggest K2V8O21 is a very promising cathode for aqueous ZIBs, which could be extended to construct other high-performance cathode materials with a similar crystal structure (e.g. β-Na0.33V2O5, Li0.3V2O5, Ag0.33V2O5, etc.) for Zinc storage.

    Electrochimica Acta, 2017
    Co-Authors: Baozheng Jiang, Liubing Dong, Feiyu Kang
    Abstract:

    Abstract Rechargeable Zinc Ion battery is considered as one of the most potential energy storage devices for large-scale energy storage system due to its safety, low-cost, high capacity and nontoxicity. However, only a few cathode materials have been studied for rechargeable Zinc Ion batteries. Here, we firstly report manganese sesquioxide (Mn 2 O 3 ) with Mn(III) state as cathode material for rechargeable Zinc Ion battery. The α-Mn 2 O 3 cathode displays a reversible capacity of 148 mAh g −1 , which is relatively high among all the reported cathode materials for ZIB. The cathode also exhibits good rate capability and excellent cycling stability with a long cycle life up to 2000 times. The Ion storage mechanism of α-Mn 2 O 3 in Zinc Ion battery was also revealed. The pristine α-Mn 2 O 3 undergoes a reversible phase transitIon from bixbyite structure to layered-type Zinc birnessite during the electrochemical Zinc Ion insertIon and extractIon. The results not only benefit for the practical applicatIon of rechargeable Zinc Ion battery, but also broaden the horizons of understanding the electrochemical behavior and mechanism of rechargeable Zinc Ion batteries.

  • concentrated dual catIon electrolyte strategy for aqueous Zinc Ion batteries
    Energy and Environmental Science, 2021
    Co-Authors: Yunpei Zhu, Yongjiu Lei, Yi Cui, Jun Yin, Xueli Zheng, Abdulhamid M Emwas, Omar F Mohammed, Husam N Alshareef
    Abstract:

    Rechargeable Zn-Ion batteries are highly promising for statIonary energy storage because of their low cost and intrinsic safety. However, due to the poor reversibility of Zn anodes and dissolutIon of oxide cathodes, aqueous Zn-Ion batteries encounter rapid performance degradatIon when operating in conventIonal low-concentratIon electrolytes. Herein, we demonstrate that an aqueous Zn2+ electrolyte using a supporting Na salt at a high concentratIon is efficient to address these issues without sacrificing the power densities, cycling stability, and safety of Zinc-Ion batteries. We show that the high-concentratIon solute minimizes the number of free water molecules and the changes in the electronic state of the electrolyte. A combinatIon of experimental and theoretical investigatIons reveals that a unique interphase, formed on the Zn anode, enables reversible and uniform Zn plating. Utilizing a cathode of sodium vanadate synthesized through a scalable strategy, the Zn–sodium vanadate battery with the concentrated bi-catIon electrolyte shows improved cycling stability, decent rate performance, and low self-discharge. This work provides new insights on electrolyte engineering to achieve high-performance aqueous batteries.

    Co-Authors: Jun Ming, Jing Guo, Chuan Xia, Wenxi Wang, Husam N Alshareef
    Abstract:

    Abstract The increasing global demand for energy and the potential environmental impact of increased energy consumptIon require greener, safer, and more cost-efficient energy storage technologies. Lithium-Ion batteries (LIBs) have been successful in meeting much of today’s energy storage demand; however, lithium (Li) is a costly metal, is unevenly distributed around the world, and poses serious safety and environmental concerns. Alternate battery technologies should thus be developed. Zinc-Ion batteries (ZIBs) have recently attracted attentIon due to their safety, environmental friendliness, and lower cost, compared to LIBs. They use aqueous electrolytes, which give them an advantage over multivalent Ion batteries (e.g., Mg2+, Ca2+, Al3+) that require more complex electrolytes. However, as with every new technology, many fundamental and practical challenges must be overcome for ZIBs to become commercial products. In this manuscript, we present a timely review and offer perspectives on recent developments and future directIons in ZIBs research. The review is divided into five parts: (i) cathode material development, including an understanding of their reactIon mechanism; (ii) electrolyte development and characterizatIon; (iii) Zinc anode, current collector, and separator design; (iv) applicatIons; and (v) outlook and perspective.

  • highly stable aqueous Zinc Ion storage using a layered calcium vanadium oxide bronze cathode
    Angewandte Chemie, 2018
    Co-Authors: Chuan Xia, Jing Guo, Xixiang Zhang, Husam N Alshareef
    Abstract:

    Cost-effective aqueous rechargeable batteries are attractive alternatives to non-aqueous cells for statIonary grid energy storage. Among different aqueous cells, Zinc-Ion batteries (ZIBs), based on Zn2+ intercalatIon chemistry, stand out as they can employ high-capacity Zn metal as the anode material. Herein, we report a layered calcium vanadium oxide bronze as the cathode material for aqueous Zn batteries. For the storage of the Zn2+ Ions in the aqueous electrolyte, we demonstrate that the calcium-based bronze structure can deliver a high capacity of 340 mA h g-1 at 0.2 C, good rate capability, and very long cycling life (96 % retentIon after 3000 cycles at 80 C). Further, we investigate the Zn2+ storage mechanism, and the corresponding electrochemical kinetics in this bronze cathode. Finally, we show that our Zn cell delivers an energy density of 267 W h kg-1 at a power density of 53.4 W kg-1 .

    Abstract:

    In this work, a microwave approach is developed to rapidly synthesize ultralong Zinc pyrovanadate (Zn3 V2 O7 (OH)2 ·2H2 O, ZVO) nanowires with a porous crystal framework. It is shown that our synthesis strategy can easily be extended to fabricate other metal pyrovanadate compounds. The Zinc pyrovanadate nanowires show significantly improved electrochemical performance when used as intercalatIon cathode for aqueous Zinc-Ion battery. Specifically, the ZVO cathode delivers high capacities of 213 and 76 mA h g-1 at current densities of 50 and 3000 mA g-1 , respectively. Furthermore, the Zn//ZVO cells show good cycling stability up to 300 cycles. The estimated energy density of this Zn cell is ≈214Wh kg-1 , which is much higher than commercial lead-acid batteries. Significant insight into the Zn-storage mechanism in the pyrovanadate cathodes is presented using multiple analytical methods. In additIon, it is shown that our prototype device can power a 1.5 V temperature sensor for at least 24 h.
