摘要： A material for a cathode is made of a carbon material hard to turn to graphite and obtainable by burning a carbon precursor. For this carbon material having the graphitization resistance, the weight % Ps of carbon in the material is smaller than 0.59 or the stacking index SI is smaller than 0.76. This carbon has a structure of stacked layers, which is determined by the diffraction peak due to the (002) plane of the crystal lattice, and the X-ray diffraction spectrum on the side of an angle lower than the diffraction peak among the X-ray diffraction spectrum. The average Nave of the number of stacked layers is smaller than 2.46. Alternatively, letting the burning temperature be T °C, and the half-width of a peak appearing near 1,340 cm-1 in the Raman spectrum be HW, the following condition is satisfied: HW > 138-0.06 T. This carbon material is manufactured by thermally treating a carbon precursor by burining it in an inert gas atmosphere flown at a flow rate of 0.1 ml per minute or more per one gram of the carbon precursor at a temperature of 600 °C or high, or in an atmosphere pressurized at 50 kPa or less at a temperature of 600 °C or high. In this case, the carbon precursor is placed in a layer so that the contact area of the precursor with the atmosphere is 10 cm2 or more.

摘要： A gel electrolyte secondary cell in which discharge capacity loss can be suppressed even with the use of a graphitized carbonaceous material of a small particle size as a negative electrode material to assure low impedance, superior cell voltage and load characteristics and high charging/discharging efficiency. To this end, a graphitized carbonaceous material prepared by firing meso-carbon micro-beads is used as a material for a negative electrode 9.

摘要： A negative electrode material for secondary cells for nonaqueous electrolytic solution realizing a high charge-and-discharge capacity and a high charge-and-discharge efficiency. The electrode material contains a product of carbonization of at least one member selected from among coffee bean, tea leaf, canes, corns, fruits, straws and chaffs; or contains a carbonaceous material resulting from a vegetable polymer and containing metal elements, phosphorus and/or sulfur in a total amount of 0.2 to 20 wt.% in terms of elements; or it contains a carbonaceous material having a diffraction peak at an angle of diffraction (i.e., 2υ) of 30 to 32 degrees in the pattern of X-ray powder diffraction (CuKα). Such a negative electrode material is produced by firing at least one member selected from among coffee bean, tea leaf, canes, corns, fruits, straws and chaffs or a mixture obtained by adding at least one member selected from among metal elements, phosphorus and sulfur to a crystalline or fibrous cellulose to effect carbonization. The obtained material is used in producing a secondary cell for a nonaqueous electrolytic solution fitted with a positive electrode made of a lithium double oxide and a negative electrode made of a carbonaceous negative electrode material capable of doping with lithium ions and dedoping as an active material of the negative electrode as the carbonaceous negative electrode material.
