ABSTRACT:
The present invention provides an electrochemical cell or battery which has a non-metallic negative electrode (anode). That is, no solid metal, free metal, active material is used in the cell. Rather than the conventional solid lithium metal anode, the active material of the new electrode comprises substituted carbon active material. The substituted carbon is carbonaceous material arranged in a disordered or ordered graphite structure, where atoms of carbon have been substituted in such structure by at least one other element. The invention also provides carbonaceous materials which are non-graphitic and considered amorphous, non-crystalline, highly disordered, which also have substituted therein elements other than carbon. The invention also provides a process for making such substituted carbons and for preparing an anode containing the substituted carbon.
