| When the battery like pa2487ur is charged, the lithium ions in the cathode material (lithium compound) migrate via a separator to between the layers of carbon material that form the anode, and a charging current flows. |
When the battery like pa3383u-1brs is discharged, the lithium ions in the carbon material that form the anode migrate via a separator to the cathode material (lithium compound), and a discharging current flows. |

- LiMn2O4+Cn —> Li1-XMn2O4+CnLix

| Lithium ion rechargeable batteries such as pa3107u-1bas operate based simply on this theory of lithium ions migrating between the cathode and anode. Lithium ion rechargeable batteries e.g. pa3291u-1brs are therefore fundamentally different from non-rechargeable lithium batteries like pa3384u-bas in that the basic form of the cathode and anode materials does not change. |
