polyaniline intercalated Manganese Dioxide nanolayers as a high performance cathode material for an aqueous zinc ion battery
Nature Communications, 2018Co-Authors: Jianhang Huang, Zhuo Wang, Mengyan Hou, Xiaoli Dong, Yao Liu, Yonggang Wang, Yongyao XiaAbstract:Rechargeable zinc-Manganese Dioxide batteries that use mild aqueous electrolytes are attracting extensive attention due to high energy density and environmental friendliness. Unfortunately, Manganese Dioxide suffers from substantial phase changes (e.g., from initial α-, β-, or γ-phase to a layered structure and subsequent structural collapse) during cycling, leading to very poor stability at high charge/discharge depth. Herein, cyclability is improved by the design of a polyaniline-intercalated layered Manganese Dioxide, in which the polymer-strengthened layered structure and nanoscale size of Manganese Dioxide serves to eliminate phase changes and facilitate charge storage. Accordingly, an unprecedented stability of 200 cycles with at a high capacity of 280 mA h g-1 (i.e., 90% utilization of the theoretical capacity of Manganese Dioxide) is achieved, as well as a long-term stability of 5000 cycles at a utilization of 40%. The encouraging performance sheds light on the design of advanced cathodes for aqueous zinc-ion batteries.

Zn-MnO2 batteries offer high energy density, but phase changes that lead to poor cathode stability hinder development of rechargeable versions. Here the authors report structurally reinforced polyaniline-intercalated MnO2 nanolayers that boost performance by eliminating phase transformation.

mineralized Manganese Dioxide channel as the stent coating for in situ precise tumor navigation
Nano Research, 2020Co-Authors: Junyuan Xiao, Yiran Zhang, Tonglei Fang, Tianwen Yuan, Qinghua Tian, Jingjing Liu, Yingsheng Cheng, Yueqi Zhu, Liang Cheng, Wenguo CuiAbstract:Drug-eluting stent (DES) is a promising strategy for esophageal cancer. However, full-covered drug-loaded stents cause damage to non-tumor tissue in the esophagus, and the development controlled-release system to prevent non-tumor tissue injure is currently a major challenge. Here, in situ mineralized Manganese Dioxide coating on Ce6 embedded electrospun fibers covered stent was developed for effective tumor therapy via intraluminal photodynamic therapy (PDT), which could reduce phototoxicity to normal esophageal tissue. Oxidation of Manganese ions, which was previously swelled between fibers, was used to accomplish mineralization. After implantation, the Manganese Dioxide coating in situ reacts with tumor endogenous H+ and H2O2, which, on the one hand, could effectively alleviate the hypoxic microenvironment which leads to resistance to PDT, and on the other hand, could expose the Ce6-fibers below the coating for intraluminal PDT. In addition, due to the slow degradation of the coating, this stent could own sustained photodynamic performance for up to one month. Notably, the PDT efficiency of the stent was investigated on orthotopic rabbit esophageal cancer models. Overall, this work suggests that in situ mineralized Manganese Dioxide coated electrospun fibers covered stent may provide a new strategy for advanced esophageal cancer patients as a functional drug delivery platform.

rechargeable aqueous zinc Manganese Dioxide batteries with high energy and power densities
Nature Communications, 2017Co-Authors: Ning Zhang, Fangyi Cheng, Liubin Wang, Xinghui Long, Fujun Li, Jun ChenAbstract:Although alkaline zinc-Manganese Dioxide batteries have dominated the primary battery applications, it is challenging to make them rechargeable. Here we report a high-performance rechargeable zinc-Manganese Dioxide system with an aqueous mild-acidic zinc triflate electrolyte. We demonstrate that the tunnel structured Manganese Dioxide polymorphs undergo a phase transition to layered zinc-buserite on first discharging, thus allowing subsequent intercalation of zinc cations in the latter structure. Based on this electrode mechanism, we formulate an aqueous zinc/Manganese triflate electrolyte that enables the formation of a protective porous Manganese oxide layer. The cathode exhibits a high reversible capacity of 225 mAh g−1 and long-term cyclability with 94% capacity retention over 2000 cycles. Remarkably, the pouch zinc-Manganese Dioxide battery delivers a total energy density of 75.2 Wh kg−1. As a result of the superior battery performance, the high safety of aqueous electrolyte, the facile cell assembly and the cost benefit of the source materials, this zinc-Manganese Dioxide system is believed to be promising for large-scale energy storage applications. The development of rechargeable aqueous zinc batteries are challenging but promising for energy storage applications. With a mild-acidic triflate electrolyte, here the authors show a high-performance Zn-MnO2 battery in which the MnO2 cathode undergoes Zn2+ (de)intercalation.
