| 1 | 锂离子电池用三维多孔V_(x)O_(y)@Cu复合负极材料的制备及其储能性能显示文摘为了提高锂离子电池的能量密度,通过非溶剂致相分离和热处理制备了三维连续多孔矾氧化物@铜复合薄膜,用作锂离子电池的负极材料,并对其储能性能进行测试。结果表明:该复合膜有发达的三维铜通道,具有适当的孔径(10-20μm),而矾氧化物颗粒通过热处理可以粘附在三维铜集流体上;在100 mA/g的电流密度下,200次循环后,活性物质质量分数为3%、5%的复合电极材料的比容量分别高达455.7 mA·h/g、477.2mA·h/g,同时表现出良好的倍率性能。因此,三维多孔结构不仅可以缩短电子/离子的传输路径,而且可以诱导空间受限的矾氧化物,为矾氧化物的体积膨胀/收缩提供了一个稳定的空间来限制粉化。 | 雷中祥 解刚 陈泽钧 | 2021 | 天津工业大学学报2021，40，6： | 1 |
| 2 | Nonsolvent-induced phase separation-derived TiO_(2) nanotube arrays/porous Ti electrode as high-energy-density anode for lithium-ion batteries显示文摘TiO_(2) nanotube arrays,growing on three-dimensional(3 D)porous Ti membrane,were synthesized using a facile nonsolvent-induced phase separation and anodization process.The length of those three-dimensional nanotube arrays could be tuned by prolonging the anodizing time.When the anodizing time is 8 h,the three-dimensional TiO_(2) nanotube arrays/porous Ti electrode exhibits well cycling stability and ultra-high specific capacity,which is used in lithium-ion batteries,attributed to the high utilization rate of the substrate and the high growth intensity of the active materials.Three-dimensional TiO_(2) nano tube arrays/porous Ti electrode,at 100μA·cm^(-2) with 8 h anodizing time,shows a typical discharge plateau at 1.78 V and exhibits the specific capacity with 2126.7μAh·cm^(-2),The novel nanotube arrays@3 D porous architecture effectively shortens the electron/ion transmission path,which could pave way for optimizing the design of highperformance anode materials for next-generation energy storage system. | Zhi-Jia Zhang Jun Zhao Zhi-Jun Qiao Jia-Min Wang Shi-Hao Sun Wen-Xing Fu Xi-Yuan Zhang Zhen-Yang Yu Yu-Hai Dou Jian-Li Kang Ding Yuan Yue-Zhan Feng Jian-Min Ma | 2021 | Rare Metals2021，40，2： | 1 |
