Nanostructured materials lie at the heart of fundamental advances in efficient energy storage and/or conversion, in which surface processes and transport kinetics play determining roles. This review describes recent developments in the synthesis and characterization of composites which consist of lithium metal phosphates (LiMPO(4), M = Fe, Co, Ni, Mn) coated on nanostructured carbon architectures (unordered and ordered carbon nanotubes, amorphous carbon, carbon foams). The major goal of this review is to highlight new progress in using different three dimensional nanostructured carbon architectures as support for the phosphate based cathode materials (e.g.: LiFePO(4), LiCoPO(4)) of high electronic conductivity to develop lithium batteries with high energy density, high rate capability and excellent cycling stability resulting from their huge surface area and short distance for mass and charge transport.
纳米结构材料在高效储能和/或转换的基础研究中处于核心地位,其中表面过程和传输动力学起着决定性的作用。本综述描述了在合成和表征复合材料方面的最新进展,这些复合材料由纳米结构碳结构(无序和有序的碳纳米管、无定形碳、碳泡沫)上覆盖的锂金属磷酸盐(LiMPO(4),M = Fe、Co、Ni、Mn)组成。本综述的主要目的是强调使用不同的三维纳米结构碳结构作为基于磷酸盐的正极材料(例如:LiFePO(4)、LiCoPO(4))的支撑物的新进展,以开发具有高能量密度、高倍率性能和优异循环稳定性的锂电池,这是由于它们具有巨大的表面积和短的质量和电荷传输距离。
