Fit-for-Purpose Battery Safety Testing
Battery developers can now verify new formulations’ safety in early-stage testing with less material and faster turnaround times than late-stage safety testing.
Dual Testing Modes
- Scanning operating mode assesses thermal abuse, thermal degradation, onset temperature, heat of reaction and material cross-reaction
- Isothermal operating mode evaluates heat flow during Solid Electrolyte Interface (SEI) formation, charge/discharge, overcharge, and overdischarge
Coin Cell Capsule
New coin cell capsules are compatible with 2032 and any 20 mm diameter coin cell. With its fit-for-purpose design, it suits testing of coin cells without teardown, providing accurate whole-cell safety testing previously impractical on a DSC.
- Coin cell standard capsules maintain thermal signal throughout the full sample range
- Coin cell cycling capsules optimize heat flow during isothermal cycling
- 20 mm classic aluminum pans for material samples
