• Voltage monitoring supports state-of-charge and short circuit analysis

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

Large Format DSC Cell Technology

The large format DSC cell’s exceptional reliability, accuracy, and reproducible heat flow measurements enable detection of even weak thermal transitions, revealing the early signs of battery degradation or failure. This reliability enables battery scientists to:
