Anode material for lithium secondary batteries and lithium secondary batteries

002 The present invention is to provide a lithium ion secondary battery that realizes to raise an initial charge and discharge efficiency without deteriorating its charge and discharge characteristic in comparison with the conventional technology.A carbon material and a lithium ion secondary battery using the carbon material as the anode material, wherein the face interval dof the carbon material determined by an X ray diffraction apparatus is not less than 0.340 nm and not more than 0.370 nm, and further, V/V representing a ratio of a volume V of pores having diameters from not less than 1 nm to less than 10 nm in the carbon material with respect to a volume V of pores having diameters from not less than 10 nm to less than 100 nm therein is not more than 0.2.
