A hierarchical Ni foam@Co3O4 pseudocapacitors materials were synthesized with Co(NO3)2·6H2O as raw materials and urea as a precipitating agent by a hydrothermal and annealing treatment.The phase structure,morphology and capacitance performance of the synthesized samples were characterized.The results show that the Co3O4 flowers composed of Co3O4 nanowires standing on the Ni foam.The Ni foam@Co3O4 has an excellent electrochemical capacitance,and the area specific capacitance is 1350mF/ cm2 (~750 F/g).

富锂层状正极材料在在4.50V以下首次充放电过程与普通三元的电化学行为并无差异,在充电电位4.50V,Li2MnO3材料被激活,此时锂离子从锂层脱出并伴随着产生O空位,随之形成层状MnO2组分.[1] 材料在初次充放电过程的结构变化至关重要,Mohanty et al 采用原位XRD测试Li1.2Co0.1Mn0.55Ni0.15O2电极,发现了峰位偏移和相结构调整现象.
以ZnSe和ZnTe纳米晶为代表的锌基半导体纳米晶,不仅具备优异的光电特性,还具有良好的环境和生物兼容性;是理想的发光和生物标记材料.近年来锌基半导体纳米晶在合成和光学性能调控方面都获得了明显进展,但在其能级结构表征方面却进展缓慢,特别是在其揭示能级结构与物性参数(尺寸、形貌、结构)之间关联方面缺乏系统研究.
磷酸铁锂(LFP)和磷酸钒锂(LVP)都是现在研究或者应用的主流聚阴离子锂离子正极材料.磷酸铁锂本身的结构特征[1]让其具有了颇为优异的性能,特别是安全性高和原材料廉价环保的特点使得其在诸如电动汽车、便携式移动设备电源、储能电源等领域发挥着重要的作用,磷酸钒锂的理论比容量高,但是容量衰减的较快,而且原料昂贵.考虑到他们性能上的优缺点,制备LFP和LVP的杂化材料是现在一个研究热点.
