Abstract: An object of the present invention is to provide a cathode active material which contains small-particle sized and low-crystalline lithium transition metal silicate and which undergoes charge-discharge reaction at room temperature. The cathode active material for a non-aqueous electrolyte secondary battery is characterized by containing a lithium transition metal silicate and exhibits diffraction peaks having half widths of 0.175 to 0.6°, the peaks observed through powder X-ray diffractometry within a 2? range of 5 to 50°.

Abstract: A particulate mixture etc., which can be used as a precursor of lithium transition metal silicate-type compound of small particle size and low crystallinity, is provided. Further, a cathode active material that can undergo charge-and-discharge reaction in room temperature, and comprises lithium transition metal silicate-type compound, is provided. It is a mixture of silicon oxide particulates, transition metal oxide particulates, and lithium transition metal silicate particulates, and its powder X-ray diffraction measurement shows diffraction peaks near 2?=33.1° and near 2?=35.7°, and said silicon oxide particulates and said transition metal oxide particulates are amorphous, and said lithium transition metal silicate particulates are in a microcrystalline or amorphous state. Furthermore, a cathode active material obtained by grinding the active material aggregate obtained by heat-treating this particulate mixture is provided.

Abstract: A saddle riding type vehicle includes a balancer beam rotatably mounted on a vehicle body to cause a right wheel and a left wheel to move up and down in opposite directions, and is capable of making turns by leaning the vehicle body. The saddle riding type vehicle also includes a headlight, a drive mechanism arranged to rotate the headlight, a front detector arranged to detect a rotation angle of the balancer beam relative to the vehicle body, and a controller programmed to control the drive mechanism based on a result of detection by the front detector. The rotation angle detected by the front detector corresponds to an angle of the vehicle body leaning sideways relative to a traveling surface (relative lean angle). The controller controls the drive mechanism based on such result of detection by the front detector. The headlight can therefore illuminate directions of movement properly.
