Lithium-ion batteries (LIBs) have become the predominant power source for portable electronics for many years in virtue of the advantages of high energy density, long lifespan and environmental benignity.In recent decades, the continuously surging demand in large-scale energy applications such as electric vehicles and electric grids boosts numerous interests in seeking for high-performance electrode materials that can store more energy efficiently.Metal oxides (e.g., CoxOy) have been regarded as very appealing candidates for this purpose because of their much higher capacity than that of conventional graphite.However, they also suffer from unstable structure,poor conductivity and sluggish kinetics for charge transfer and ionic diffusion during the electrochemical reactions.

金属空气电池属于燃料电池的一种,其燃料采用金属(镁、铝、锌等)及其合金板,其电解质可以采用中性盐溶液或碱溶液,其阴极为催化层和带有防水透气层的多孔扩散电极。在金属空气电池的开发研究过程中,其阴极高效氧还原催化剂的开发研究是其重要问题之一。研究了催化剂前体聚合卟啉(PTPPM)和聚合酞菁配合物(PPcM) (M=Co、Fe)的制备方法和工艺。用UV-vis、IR对催化剂前驱体进行表征,结果表明,得到
储热材料在压制成型过程或封装填充过程中易产生空间分布不均，加之储热材料自身热阻的存在，以及换热器结构本征特性，极可能导致整套相变储/释热换热器内部储热材料温度分布的不均匀性，即沿单体换热元件(管束)轴向方向以及沿整套换热器迎风面垂直方向(热流体流动方向)，储热材料的温度梯度可能过大，这将造成在换热器的某些管束区域内，储热材料的温度已越过相变点，且达到最高允许温度值，而某些管束区域内，储热材料的温度
