Current collectors are conductive components in batteries that collect and distribute electrical current between electrodes and external circuits.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Purity | >99.5% for aluminum, >99.9% for copper | |
| Thickness | 6-20 μm | |
| Tensile Strength | 150-300 MPa | |
| Surface Roughness | Ra 0.1-0.5 μm | |
| Electrical Conductivity | >58 MS/m for copper, >35 MS/m for aluminum |

Aluminum is used for cathodes because it forms a protective oxide layer that prevents corrosion in high-voltage environments, while copper is used for anodes because it remains stable at lower potentials and doesn't form lithium alloys that could degrade performance.
Thinner collectors reduce battery weight and volume, improving energy density, but must maintain sufficient mechanical strength and conductivity. Optimal thickness balances these factors for specific applications.
