摘要： A positive-electrode material for a lithium secondary battery is provided. The material includes a lithium oxide compound or a complex oxide as reactive substance. The material also includes at least one type of carbon material, and optionally a binder. A first type of carbon material is provided as a coating on the reactive substance particles surface. A second type of carbon material is carbon black. And a third type of carbon material is a fibrous carbon material provided as a mixture of at least two types of fibrous carbon material different in fiber diameter and/or fiber length. Also, a method for preparing the material as well as lithium secondary batteries including the material is provided.

摘要： A process for the preparation of nanofilament particles of SiOx in which x is between 0.8 and 1.2, the process comprising: a step consisting of a fusion reaction between silica (SiO2) and silicon (Si), at a temperature of at least about 1410° C., to produce gaseous silicon monoxide (SiO); and a step consisting of condensation of the gaseous SiO to produce the SiOx nanofilament particles. The process may also comprising using carbon.

摘要： A method for producing an electrode material for a lithium-ion secondary battery. The method includes the following steps: (a) mixing components of a basic ingredient or active substance of electrode material and a conductive carbon material to obtain a conductive carbon material-composited material; (b) mixing the conductive carbon material-composited material and a surface layer-forming material; an (c) burning the mixture obtained at step (b) to obtain the electrode material. Also, a lithium-ion secondary battery including an electrode which includes the material.
