Current collector
A current collector is a conductive support that collects electrons from the electrode and conveys them to the terminal, or conveys them from the terminal to the electrode.

In context
Thin metal foil is widely used in lithium-ion cells. Stability at the reaction potential and processability are considered together.
Example
The current collector's main roles are electron transport and electrode support, rather than charge storage.
Key distinction
Do not treat metal foil and the active material layer as the same material.
