Production run spot checks of materials for lithium-ion batteries and fuel cells could be a thing of the past because of a process developed at Oak Ridge National Laboratory. The infrared/thermal nondestructive evaluation technique invented by a team led by David Wood examines key parameters such as porosity and thickness of the coating in real time without destroying product.
