6 Frequently Asked Questions about “Battery module back passivation”
What is a passivation layer in a lithium battery?
Passivation is a very thin, high resistant, self-assembled layer formed on the surface of the lithium anode. It is formed as a result of a chemical reaction between the battery electrolyte and the lithium anode. Without the passivation layer, this type of lithium battery would not exist because the lithium would discharge and degrade quite rapidly.
What is passivation in a lithium thionyl chloride battery cell?
Passivation in a lithium thionyl chloride battery cell is a chemical reaction between the solid metallic lithium metal and the liquid catholyte (cathode and electrolyte) in the cell. It is a self-assembled, thin, highly resistant layer of lithium chloride crystals on the surface of the lithium metal.
How does temperature affect the passivation layer of a battery?
Higher temperature causes a thicker passivation layer, thus storing at cooler (room) temperature helps mitigate passivation layer growth. Consequently, using fresher batteries helps assure a less resistive passivation layer has formed in the battery. The passivation layer is diminished by appropriate electrical current flow through the cell.
What is battery de-passivation?
Battery de-passivation is a process that “conditions” the battery for proper operation.
How does a passivation layer affect a cell?
The most obvious affect of the passivation layer is voltage delay. Voltage delay will occur when a load is placed on the cell as illustrated in the following drawing: After a load is applied to a cell, the high resistance of the passivation layer causes the voltage of the cell to drop rapidly.
What causes a voltage delay in a passivated cell?
As the passivation layer thickens, the voltage delay becomes more severe. On continued discharge though, the voltage of a passivated cell will rise to a level equivalent to the load voltage of an unpassivated cell. Adjusting storage conditions to reduce the likelihood of passivation is the best way to reduce voltage delay problems.
