Abstract
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.
