A method for testing a sample of a battery cell, comprising:
- arranging the sample of the battery cell in a sample pan of a test crucible;
- arranging a spacer on the sample of the battery cell;
- sealing the sample pan;
- and
- performing differential scanning calorimetry (DSC) testing of the sample relative to a reference crucible, wherein the reference crucible does not include a reference sample during the DSC testing.
