CoO 2 + Li + + e - → LiCoO 2. Oxidation takes place at the anode. There, the graphite intercalation compound LiC 6 forms graphite (C 6) and lithium ions. The half-reaction is: LiC 6 → C 6 + Li + + e -. Here is the full reaction (left to right = discharging, right to left = charging): LiC 6 + CoO 2 ⇄ C 6 + LiCoO 2.
On discharge, the anode undergoes oxidation, or loss of electrons, and the cathode sees a reduction, or a gain of electrons. Charge reverses the movement. Li ion batteries come in many varieties but all …

Lithium/BCE/cathode batteries were assembled through the same lamination process that was used for the lithium symmetrical cells and sealed in a 20 mm diameter coin cell with typically 3 bars of pressure. The batteries were then placed inside a Memmert IPP30 climatic chamber and cycled at different temperatures from 40 °C to 80 °C.
Rechargeable lithium batteries have conquered the markets for portable consumer electronics and, recently, for electric vehicles. Lithium, the lightest and one of the most reactive of metals, having the greatest electrochemical potential ( E °=–3.045 V), provides very high energy and power densities in batteries.
