Consider the phenomena of Li intercalation of graphite at the anode of a Lithium Ion battery, something you should have run across in your review. Intercalation of lithium metal in between the layers of graphite forms a thermodynamically stable compound whose formula is LiC6. At the cathode of a lithium ion battery is another bizarre chemical, typically lithium cobalt oxide (LiCoO2). The two half cell reactions can be expressed as follows: Li+1 + e- + C6 à LiC6                            Eo =...
