| 1 | Advances in the structure design of substrate materials for zinc anode of aqueous zinc ion batteries显示文摘Aqueous zinc ion batteries(AZIBs) demonstrate tremendous competitiveness and application prospects because of their abundant resources,low cost, high safety, and environmental friendliness. Although the advanced electrochemical energy storage systems based on zinc ion batteries have been greatly developed, many severe problems associated with Zn anode impede its practical application, such as the dendrite formation,hydrogen evolution, corrosion and passivation phenomenon. To address these drawbacks, electrolytes, separators, zinc alloys, interfacial modification and structural design of Zn anode have been employed at present by scientists. Among them, the structural design for zinc anode is relatively mature, which is generally believed to enhance the electroactive surface area of zinc anode, reduce local current density, and promote the uniform distribution of zinc ions on the surface of anode. In order to explore new research directions, it is crucial to systematically summarize the structural design of anode materials. Herein, this review focuses on the challenges in Zn anode, modification strategies and the three-dimensional(3D) structure design of substrate materials for Zn anode including carbon substrate materials, metal substrate materials and other substrate materials. Finally, future directions and perspectives about the Zn anode are presented for developing high-performance AZIBs. | Sinian Yang Hongxia Du Yuting Li Xiangsi Wu Bensheng Xiao Zhangxing He Qiaobao Zhang Xianwen Wu | 2023 | Green Energy & Environment2023，8，6： | 0 |
| 2 | Hydrated ammonium manganese phosphates by electrochemically induced manganese-defect as cathode material for aqueous zinc ion batteries显示文摘Aqueous zinc ion batteries(AZIBs) with the merits of low cost, low toxicity, high safety, environmental benignity as well as multi-valence properties as the large-scale energy storage devices demonstrate tremendous application prospect. However, the explorations for the most competitive manganese-based cathode materials of AZIBs have been mainly limited to some known manganese oxides. Herein, we report a new type of cathode material NH_(4)MnPO_(4)·H_(2)O(abbreviated as AMPH) for rechargeable AZIBs synthesized through a simple hydrothermal method. An in-situ electrochemical strategy inducing Mn-defect has been used to unlock the electrochemical activity of AMPH through the initial charge process, which can convert poor electrochemical characteristic of AMPH towards Zn^(2+)and NH_(4)+into great electrochemically active cathode for AZIBs. It still delivers a reversible discharge capacity up to 90.0 m Ah/g at 0.5 A/g even after 1000thcycles, which indicates a considerable capacity and an impressive cycle stability. Furthermore, this cathode reveals an(de)insertion mechanism of Zn^(2+)and NH_(4)+without structural collapse during the charge/discharge process. The work not only supplements a new member for the family of manganese-based compound for AZIBs, but also provides a potential direction for developing novel cathode material for AZIBs by introducing defect chemistry. | Xiangsi Wu Guangli Liu Sinian Yang Yuting Li Hongqiang Wang Qingyu Li Xianwen Wu | 2023 | Chinese Chemical Letters2023，34，4： | 0 |
