Thermal image flash thermography reveals differences in thickness and composition.
A newly developed tool by Purdue University researchers to detect flaws in lithium-ion batteries as they are being manufactured is being hailed as a step toward reducing defects and inconsistencies in the thickness of electrodes that affect battery life and reliability. The electrodes, called anodes and cathodes, are copper on one side and coated with a black compound to store lithium on the other. Li-ions travel from the anode to the cathode when the battery is being charged and in the ...
