The invention provides for a lithium secondary battery using a non-aqueous solvent wherein the anode material is prepared by the pyrolysis of organic compound starting materials obtained by reacting at least one conjugated polycyclic compound with a nitro compound or with a nitrating agent. The anode material contains at least the elements carbon and nitrogen, the nitrogen content ranging from 0.5% to 6% by weight. Eighty percent or more of this nitrogen is bound to carbon by either C--N or C.dbd.N bonds. The ratio of the intensity of the x-ray photoelectron spectroscopy ("XPS") peak observed for the anode material at 401.2.+-.0.2 eV to the intensity of peak observed for the anode material at 398.8.+-.0.4 eV is 1.0:1 or more.
A lithium secondary battery using a non-aqueous solvent wherein the anode material is prepared by the pyrolysis of organic compound starting materials obtained by reacting at least one conjugated polycyclic compound with a nitrocompound or with a nitrating agent, the anode material containing at least the elements carbon and nitrogen;
An anode material for a lithium secondary battery using a non-aqueous solvent prepared by pyrolyzing organic compound starting materials obtained by reacting at least one conjugated polycyclic compound with a nitrocompound or with a nitrating agent, the anode material containing at least the elements carbon and nitrogen;
An anode material is sheet form for use in the preparation of anodes for a secondary battery, which anode material is prepared by pyrolyzing organic compound starting materials obtained by reacting at least one conjugated polycyclic compound with a nitrocompound or with a nitrating agent, the anode material containing at least the elements carbon and nitrogen;
