    摘要: A negative electrode material for lithium ion secondary batteries comprises amorphous coated particles that are composed of a plurality of consolidated particles having no specific shape, said consolidated particles being obtained by consolidating a plurality of primary spheroidized graphite particles, and 0.5-20% by mass of an amorphous carbon layer that covers the surfaces of the consolidated particles and binds the consolidated particles with each other; and 0.5-20% by mass of a highly crystalline carbon layer that is formed so as to cover the outer surfaces of the amorphous coated particles and has an interplanar distance ascribed to CVD processing of 0.335 nm or more but less than 0.3369 nm. The negative electrode material for lithium ion secondary batteries is also characterized by having a porosity of 5% by volume or less, and a method for producing the negative electrode material for lithium ion secondary batteries.

    摘要: The present invention relates to a graphite particle and a carbon-graphite composite particle both suitable for use in electrode for lithium ion secondary battery, as well as to processes for producing these particles. The graphite particle of the present invention has an average particle diameter of 5 to 50 μm, wherein one or more recesses having a depth of 0.1 to 10 μm are formed in the surface. The graphite particle is produced by a mixing step for mixing raw material graphite particles and recess-forming particles, a press molding step for press-molding the mixture composed of the raw material graphite particles and the recess-forming particles to obtain a molded article, a pulverization step for pulverizing the molded article, and a separation step for separating and removing the recess-forming particles from the pulverized molded article. The carbon-graphite composite particle of the present invention is produced by performing a thermal CVD step which comprises covering the surface of the above-mentioned graphite particle with a carbon layer.
