Cell Architecture and Composition

The LiFePO4 battery features a sophisticated electrochemical structure:

  • Cathode (Positive Electrode): Composed of $LiFePO_4$ material with an olivine structure, connected via high-purity aluminum foil.

  • Anode (Negative Electrode): Composed of carbon (graphite), connected via conductive copper foil.

  • Separator: A specialized polymer membrane located between the electrodes. It is engineered to be ionically conductive but electronically insulating, allowing lithium ions to migrate while preventing internal short circuits.

  • Electrolyte & Housing: The internal cavity is filled with high-performance electrolyte and hermetically sealed within a robust metal or aluminum-plastic casing.
