    摘要： The present invention provides a secondary cell with an enlarged capacity, therefore enlarging a discharge capacity as well as improving charge/discharge cycle characteristics. The secondary cell has a carbon material for a negative electrode, wherein the spacing of (002) planes d.sub.002, a true density, a crystallite size in the direction of c axis Lc, a and specific surface area of the carbon material are restricted to ranges of 3.39.ANG. to 3.62.ANG., 1.70 g/cc to 2.20 g/cc, 10.ANG. to 50.ANG., and 2 m.sup.2 /g to 50 m.sup.2, respectively. The carbon material is selected from a carbon material group consisting of needle cokes, pitch cokes, and coke derived from furfuryl alcohol.

    摘要： A secondary battery is comprised at a positive electrode, an electrolyte and a negative electrode which intercalates lithium reversibly. The negative electrode uses a carbon compound having a crystal structure of graphite in which carbon (C) is partially replaced by both boron (B) and nitrogen (N) and has the formula BC.sub.3 N or in which (C) is partially replaced by boron (B) and has the formula BC.sub.3. In the battery, the positive electrode may be a metal chalcogen or metal oxide, such as FeS.sub.2, MoS.sub.2, TiS.sub.2, LiNiO.sub.2, LiMn.sub.2 O.sub.3, LiFeO.sub.2 LiCoO.sub.2 or MnO.sub.2. The electrolyte may be a nonaqueous electrolyte or a solid electrolyte. The non-aqueous electrolyte uses an organic solvent and a lithium salt.
