Measurement of Separator Contraction Behavior (TMA)

The TMA-60 Thermomechanical Analyzer is an effective tool for evaluation of the expansion and contraction behaviors of separators and other battery materials under heating.

The contraction behavior was measured for two types of separators (1 and 2) extracted from lithium ion batteries.

Sample 1 contracts in a higher temperature range than Sample 2.
