    摘要： A carbonaceous electrode having improved capacities for doping and dedoping of a cell active substance, such as lithium, and suitable for a non-aqueous solvent secondary battery, is constituted by a carbonaceous material having a true density as measured by a butanol substitution method of at most 1.46 g/cm3, a true density as measured by a helium substitution method of at least 1.7 g/cm3, a hydrogen-to-carbon atomic ratio H/C of at most 0.15 as measured according to elementary analysis, a BET specific surface area of at most 50 m2/g as measured by nitrogen adsorption BET method, and a carbon dioxide adsorption capacity of at least 10 ml/g. The carbonaceous material is advantageously produced by carbonizing an organic material originated from bamboo genera of family Gramineae, particularly genus Pleioblastus or Bambusa, at 1000-1400° C. under a reduced pressure or under a flowing inert gas stream to provide an appropriate porous structure.
