Abstract:
A positive-electrode material for a lithium secondary battery. 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.

Claim (Index 2):
A method of preparing a positive-electrode material for a lithium secondary battery, comprising:\n (a) providing a complex oxide compound as reactive substance; (b) coating the reactive substance particles surface with a carbon material; and (c) mixing the coated reactive substance with carbon black, a mixture of at least two types of fibrous carbon material different in fiber diameter and/or fiber length, and optionally a binder, wherein step (c) is performed by compression shear impact-type particle-compositing technique, wherein the complex oxide compound is a complex oxide of general formula A a M m Z z O o N n F f , and wherein:\n A represents an alkaline metal; \n M represents a transition metal, and optionally at least one non-transition metal, or a mixture thereof; \n Z represents a non-metallic element; \n N is a nitrogen atom; \n F is a fluorine atom; and \n a\u22650, m\u22650, z\u22650, o>0, n\u22650 and f\u22650, a, m, o, n, f and z being selected to ensure electro neutrality of the complex oxide.
