Carbonaceous electrode material for secondary battery and process for production thereof

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-type secondary battery, is constituted by a carbonaceous material having a specific microtexture. The carbonaceous material is characterized by ability of providing an electrochemically lithium-doped product showing a main resonance peak which is shifted by 80 - 200 ppm to a lower magnetic field side from a resonance line of LiCl as a reference substance when subjected to <7>Li-NMR spectroscopy analysis. $$
