    摘要： The invention relates to a lithium lanthanum titanate composite solid electrolyte material containing silicon in which amorphous Si or an amorphous Si compound exist in a grain boundary between crystal grains, and a method of producing the same, and belongs to a field of a lithium ion battery. According to the invention, the amorphous Si or the amorphous Si compound exist in the grain boundary between the crystal grains of the lithium lanthanum titanate. The amorphous Si or the amorphous Si compound are introduced into the grain boundary by employing a wet chemical method. In the wet chemical method, the inexpensive organosilicon compound is used as an additive, and the organosilicon compound is added into the lithium lanthanum titanate solid electrolyte material. Thus, it is possible to synthesize the lithium lanthanum titanate composite solid electrolyte material containing silicon by performing sintering when the ratio of mass of the Si or mass of the Si calculated based on mass of the Si compound to mass of the lithium lanthanum titanate is 0.27% to 1.35%.

According to the invention, the amorphous Si or the amorphous Si compound exist in the grain boundary between the crystal grains of the lithium lanthanum titanate. The amorphous Si or the amorphous Si compound are introduced into the grain boundary by employing a wet chemical method. In the wet chemical method, the inexpensive organosilicon compound is used as an additive, and the organosilicon compound is added into the lithium lanthanum titanate solid electrolyte material. Thus, it is possible to synthesize the lithium lanthanum titanate composite solid electrolyte material containing silicon by performing sintering when the ratio of mass of the Si or mass of the Si calculated based on mass of the Si compound to mass of the lithium lanthanum titanate is 0.27% to 1.35%. Grain boundary conductivity thereof is significantly improved, and therefore, total conductivity is improved. In addition, processes of the experimental method are simple and easily performed. Also, an experimental period is greatly reduced, a synthesis temperature is reduced, and energy consumption and production cost are reduced.

    摘要： An electric double layer capacitor which is usable at a high voltage without causing an irreversible current. Both a polarized positive electrode 14 and a polarized negative electrode 16 are made of the same constituents. However, a ratio of an amount of constituents of the polarized positive electrode 14 differs from that of the polarized negative electrode 16. A ratio of a capacitance of the polarized positive electrode to a capacitance of the polarized negative electrode is controlled such that the polarized positive electrode and the polarized negative electrode simultaneously reach respective potentials where the irreversible current is caused. According to this invention there is an advantage that it is possible to increase a voltage applied to the electric double layer capacitor.
