Technology Description

NREL recently developed micro-calorimeters that are highly accurate and capable of measuring heat signals of the order of a few microwatts. This technology will enable the industry to measure and distinguish between multiple heat sources within the battery and accurately identify aging mechanisms within cells. The abilities of this tool will help bridge the gap between material limitations and cell level performance. Building of the prototype was funded by the Vehicle Technologies Office.
