In recent years, it is expected to develop high performance power sources from the viewpoint of possible application as auxiliary power units for fuel cell electric vehicle. The present study investigated a development of charging-discharging electrode materials with high power and energy densities. It was revealed that control of nanoporous structure is effective for yielding high rate charging-discharging electrode materials.The research results are as follows.1.Mesoporous and macroporuos anatase-TiO_2 were successfully synthesized by a bicontinuous microemulsion-aided process and a colloidal crystal-template process, respectively. The mesopores and macropores enabled Li-salt electrolyte to penetrate smoothly, and the high surface area promoted high rate Li-intercalation reaction. However it was also found that increase in electronic conductivity of porous samples is required for yielding high performance of charging-discharging.2.Nanoporous carbons obtained by a colloidal crystal-template process showed high electric double-layer capacitive property, indicating that the formation of mesopores and macropores are indispensable for high rate ion transport.3.Mesoporous and macroporous nanocomposite of TiO_2 and carbon nanotubes were successfully synthesized for the first time. Macroporous nanocomposite of porous carbon and V_2O_5 nanolayers was also fabricated. These porous nanocomposites showed extremely high capacities at high charging-discharging rates because of coexistence of ion-transport and electron-conduting nanochannels in the materials.

近年来，从可能应用于燃料电池电动汽车的辅助动力单元的角度来看，有望开发出高性能电源。本研究探讨了高功率和能量密度充放电电极材料的发展。结果表明，控制纳米孔结构是制备高倍率充放电电极材料的有效方法。研究结果如下：1。采用微乳剂辅助双连续法和胶体晶体模板法分别成功合成了中孔锐钛酸盐和大孔锐钛酸盐。中孔和大孔使锂盐电解质能够顺利渗透，高表面积促进了高速率的锂嵌入反应。然而，我们也发现，提高多孔样品的电子导电性是产生高性能充放电的必要条件。胶体晶体模板法制备的纳米孔碳具有高的双电层容性，表明中孔和大孔的形成是实现高速率离子传输的必要条件。首次成功地合成了二氧化钛和碳纳米管的介孔和大孔纳米复合材料。制备了多孔碳和V_2O_5纳米层的大孔纳米复合材料。这些多孔纳米复合材料在高充放电速率下表现出极高的容量，因为材料中存在离子传输和电子传导的纳米通道。
