摘要
碳微纳米材料如碳纳米管、石墨烯、多孔碳等具有独特的结构与优良的导电性、超大比表面积、极佳的柔韧性和优异的电化学性质。此外,碳材料还能与过渡金属氧化物、硫族化合物、新型二维材料等无机活性材料复合以大幅提高能源器件(如锂电池、超级电容、太阳能电池和光电催化体系等)的性能。然而,如何对其性能进行精确调控仍然面临着巨大挑战。为此,需要合理设计与可控制备碳基/无机纳米复合材料,以克服传统能源材料中电荷传输受限、动力学缓慢、界面稳定性差等所导致的能量转换效率和储能密度较低的问题。近两年来,本研究团队在碳基及无机纳米复合材料的能源应用方面取得了一定进展,包括制备多核卵壳结构的碳/无机纳米材料用于锂电负极、基于柔性磷酸钒锂/碳纳米复合纤维的高倍率性能锂电正极、基于超薄硫化物纳米片/碳材料的太阳能电池和柔性能量纤维、新型光电催化剂用于氢能源转换等。
Nanocomposite based on carbon nanomaterials and other inorganic active materials(transition metal oxides, chalcogenides, etc.) can greatly improve the performances of energy devices. Here we report several feasible approaches to prepare 3D hierarchical carbon and/or inorganic based architectures with precisely-designed components and structures for energy applications: 1) CuO encapsulated mesoporous carbon multi-yolk-shell octahedra as high-stability anodes for lithium ion batteries. 2) Free-standing, flexible, binder-free Li_3V_2(PO_4)_3 encapsulated carbon nanofabric cathodes for fast charging lithium-ion batteries. 3) One-step fabrication of ultrathin MoS_2 nanofilms with high catalytic activity on transparent conductive glass for solar cells.
