ABSTRACT:
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-type secondary battery, is constituted by a carbonaceous material having a specific microtexture. The carbonaceous material is characterized by an average (002)-plane spacing of at least 0.365 nm according to X-ray diffraction method, and also a ratio .rho..sub.H /.rho..sub.B of at least 1.15 wherein .rho..sub.H denotes a density measured by using helium gas as a substitution medium and .rho..sub.B denotes a density measured by using butanol as a substitution medium.
