Molded article for negative electrode, method of producing the same and lithium secondary battery using the same.

摘要

A mixture of carbon powder and a carbonaceous binder is molded and burned in an atmosphere of nitrogen to form a carbon molded article for a negative electrode. The properties of the carbon molded article are: an interfacial distance (d002) within a range from 3.38 ANGSTROM to 3.56 ANGSTROM measured by X-ray diffraction; and a three-point strength of 100 kgf/cm<2> or greater at room temperature. A lithium secondary battery formed by using this carbon molded article as the negative electrode has a high energy density per unit volume and advantageous charge-discharge characteristics for higher loads.
