Aqueous zinc-ion batteries(ZIBs) combine the benefits of metallic Zn anodes with those of aqueous electrolytes and are well suited for large-scale energy storage because of their inherent high safety, cost-effectiveness, and eco-friendliness. Currently, the practical application of such batteries is hindered by the poor cycling performance of Zn anodes due to uncontrolled dendrite formation and severe side reactions, although recent reports suggest that these problems can be mitigated through the modification of Zn anodes with metal-based *** that the mechanisms of improving Zn deposition and the structural evolution of metal-based materials have not been systematically reviewed, we herein systematically overview the metal-based materials used to stabilize Zn anodes, starting with a brief summary of the anode working mechanism and the challenges faced by stabilized Zn anodes. Subsequently, the design principles of Zn anodes stabilized by metal-based materials and the related recent progress are reviewed, and the key challenges and perspectives for the future development of such Zn anodes are proposed.

An ultrathin and continuous li_4Ti_5O_(12) coated carbon nanofiber interlayer for high rate lithium sulfur battery

引用

Journal of Energy Chemistry 2019年第4期28卷 19-26页

作者： Decheng An Lu Shen Danni Lei Lehong Wang heng Ye Baohua li Feiyu Kang Yan-Bing He Engineering Laboratory for the Next Generation Power and Energy Storage Batteries Graduate School at Shenzhen Tsinghua University Laboratory of Advanced Materials School of Materials Science and Engineering Tsinghua University

Severe capacity fading and poor high rate performance of lithium sulfur(li–S) battery caused by "shuttle effect" and low conductivity of sulfur hampers its further developments and applications. li_4Ti_5O_(12) (LTO)possesses high lithium ion conductivity, and it is also can be used as an active adsorbent for polysulfide. Herein, fine LTO particle coated carbon nanofibers(CNF) were prepared and a conductive network both for electron and lithium ion was built, which can greatly promote the electrochemical conversion of polysulfide and improve the rate performance of li–S batteries. Meanwhile, a quantity of adsorption sites is constructed by defects of the surface of LTO-CNF membrane to effectively immobilize polysulfide. The multifunctional LTO-CNF interlayer could impede the shuttle effect and enhance comprehensive electrochemical performance of li–S batteries, especially high rate performance. With such LTO-CNF interlayer,the li–S battery presents a specific capacity of 641.9 mAh/g at 5 C rate. After 400 cycles at 1 C, a capacity of 618.0 mAh/g is retained. This work provides a feasible strategy to achieve high performance of li–S battery for practical utilization.
