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 BC3N or in which (C) is partially replaced by boron (B) and has the formula BC3. In the battery, the positive electrode may be a metal chalcogen or metal oxide, such as FeS2, MoS2, TiS2, LiNiO2, LiMn2O3, LiFeO2+L, LiCoO2 or MnO2. The electrolyte may be a nonaqueous electrolyte or a solid electrolyte. The non-aqueous electrolyte uses an organic solvent and a lithium salt.
