摘要: An object of the present invention is to provide a carbonaceous molded body for a battery electrode having high charge/discharge capacity, high initial charge/discharge efficiency, and excellent cycle life. The aforementioned object can be achieved by a carbonaceous molded body for a battery electrode of the present invention, including: carbon fibers where lithium can be doped and dedoped; and a carbonaceous material; wherein the thickness is 1 mm or less, atomic ratio (H/C) between hydrogen atoms and carbon atoms based on elemental analysis is 0.1 or less, porosity determined from bulk density of the molded body and true density of butanol is from 25 to 80%, and volatile matter content is 5.0 wt. % or less.
