Nonaqueous electrolytic secondary battery and method of producing anode material thereof

A nonaqueous electrolyte secondary battery comprising:

• a positive electrode made of a graphitic material,
• an electrolyte containing a lithium salt;
• and
• a negative electrode made of a carbonaceous material capable of occluding and releasing lithium metal or lithium,
• wherein said positive electrode is an graphitic material that has not been introduced with a conductor, the graphitic material is a graphite crystal having some of carbon atoms forming hexagonal network planes replaced by boron atoms or having boron atoms infiltrated into between layers of hexagonal network planes, and said positive electrode is formed from boron or a boron compound contained in the graphite, such that the content of boron therein is 0.05-11 wt %.
