本文总结了近年来纳米薄膜锂离子电池电极材料的研究情况,特别是本课题组在这方面的工作进展。我们从纳米颗粒和纳米结构两方面对各种纳米电极材料进行了分类和归纳,对于纳米颗粒组成的薄膜电极材料,除了对传统的锂-金属氧化物(LiMO2,LiMn2O4等)电极材料和聚阴离子型(LiFePO4等)电极材料薄膜化的研究做了介绍之外,着重介绍了一系列基于纳米效应的具有新型反应机理的正负极材料,包括二元金属化合物薄膜电极(MX)、含锂复合薄膜电极(M-LiX)以及多元复合薄膜电极(MXY,M1X-Y,M1X-M2Y)。这些新型电极材料及其反应机理的研究为锂离子电池的发展开辟了新的方向。对于纳米结构组成的薄膜电极材料,我们主要对三维结构的纳米丝电极和三维微网碳膜电极进行了介绍,指出这些三维纳米结构材料的研究将为未来三维微电池的开发奠定基础。

This review summarizes the research in nanosized thin film electrode materials for ion batteries and our progress in this field. Nanosized thin film electrode materials are introduced by dividing into nanoparticle-materials and nanostructure-materials. For nanoparticle materials, besides introducing traditional thin film electrode materials like lithium-metal oxide （LiMO2, LiMn204, etc. ） and lithium-metal polyanion （LiFePO4, etc. ）, we emphasize a series of novel thin film electrodes with new electrochemical reaction mechanisms based on nanometer- size effects, including binary metal compound （MX）, composite materials contained lithium （M-LiX） and polynary composite system （MXY, MIX-Y, M^X-M2Y）. The investigations of these new kinds of electrode materials will open new opportunity for the development of lithium ion battery. For nanostructured materials, we foeuse on three-dimensional （3D） structured electrode and carbon micro-net films electrode. These studies lay the foundations for future 3D mierobatteries.
