Compared to late-stage safety testing, battery makers can now confirm the safety of novel formulations in early-stage testing with less material and quicker turnaround times.
Dual Testing Modes
- The scanning operating mode evaluates material cross-reaction, heat of reaction, onset temperature, thermal abuse, and thermal deterioration.
- Heat flow during the development of the solid electrolyte interface (SEI), charge/discharge, overcharge, and overdischarge are assessed using the isothermal operating mode.
Coin-Cell Capsule

New coin-cell capsules work with 2032 and any 20 mm diameter coin cell. With its fit-for-purpose design, it is ideal for coin-cell testing without the need for dismantling, delivering accurate whole-cell safety testing that was previously difficult on DSCs.
- Coin-cell standard capsules preserve thermal signal over the whole sample range
- Coin-cell cycling capsules improve heat flow during isothermal cycling
- Twenty mm classic aluminum pans for material samples
Large Format DSC Cell Technology
