Abstract
A battery using carbonaceous materials with a graphite or disordered graphite structure wherein boron atoms are substituted for carbon atoms in the structure. The electrochemical potential of the carbonaceous materials is shifted as a result of such substitution, and the electrochemical capacity is increased. Both effects are desirable for anode materials in lithium ion type batteries.
