NOVELTY - The electrode material consists of a carbonaceous film covering the surface of an electrode active material consisting of a main component selected from a group including lithium cobaltate, lithium nickelate, lithium manganate and lithium titanate. The ratio of the peak intensity of the spectrum of electrode material in the wavelength range of 1360 plus minus 50 cm-1 and the peak intensity of the spectrum of electrode material in the wavelength range of 1580 plus minus 50 cm-1 at the time of performing Raman-spectrum analysis of electrode material is obtained in the range of 0.65-1.    USE - Electrode material for lithium ion battery (claimed). Uses include but are not limited to electric vehicle, portable electronic device and uninterruptible power supply (UPS) system.    ADVANTAGE - The electrode material having a stable charging/discharging cycle characteristic is obtained by enabling efficient adsorption or desorption of lithium ions by setting the ratio in an appropriate range. The quality of carbonaceous film and electronic conductivity are improved by eliminating the existence of non-volatile component of organic compound during the formation of carbonaceous film.    DETAILED DESCRIPTION - The electrode material consists of a carbonaceous film covering the surface of an electrode active material consisting of a main component selected from a group including lithium cobaltate, lithium nickelate, lithium manganate, lithium titanate and LixAyDzPO4, where A is selected from a group including cobalt (Co), manganese (Mn), nickel (Ni), iron (Fe), copper (Cu), and chromium (Cr), D is selected from a group including magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), titanium (Ti), zinc (Zn), boron (B), aluminum (Al), gallium (Ga), indium (In), silicon (Simply), germanium (Ge), scandium (Sc), yttrium (Y) and materials selected from a group of rare earth elements, x is set in the range of 0-2, y is set in the range of 0-1 and z is set in the range of 0-1.5. The ratio of the peak intensity of the spectrum of electrode material in the wavelength range of 1360 plus minus 50 cm-1 and the peak intensity of the spectrum of electrode material in the wavelength range of 1580 plus minus 50 cm-1 at the time of performing Raman-spectrum analysis of electrode material is obtained in the range of 0.65-1.
