Cell Testing
Exponent laboratories are equipped to test a large variety of cell chemistries, form factors and configurations. Our experienced engineers can design unique application specific test protocols that are tailored to evaluate a cell’s performance in its operating environment
We commonly conduct a variety of high-level performance and reliability tests on cells including:
- Normal operation evaluation
- Capacity analysis and testing to identify degradation mechanisms
- Cell performance evaluation under a variety of temperature conditions (constant or cyclic)
- Calendar life testing
- Cell shelf life testing
- Cell service life testing
- Vent testing
We also conduct cell stress tests to evaluate response to a variety of stresses including:
- Electrical
- Electrical overstress/overcharge
- Electrical overdischarge
- Electrical life cycles
- Electrical short circuit performance
- Environmental
- Heating including hot box, flame attack, and UL projectile testing
- Altitude simulation
- High/low humidity
- Mechanical
- Random and controlled impacts
- Random and controlled drops
- Steady force application
- Random and controlled vibration
- Mechanical shock
- Crush and puncture, including nail penetration
- Customized user abuse scenarios
- Vehicle accident scenarios
