Differential Scanning Calorimetry

Definition

Differential Scanning Calorimetry (DSC) is a thermal analysis technique that measures how a material's heat capacity changes as it is heated or cooled, providing insights into phase transitions, crystallization behavior, and thermal stability. This method is crucial in evaluating the quality and performance of materials used in solid-state batteries, allowing for the assessment of their thermal properties and any changes that may occur during production and operation.
