Abstract
A metallic particle detector system includes a particle detection unit with a detector configured to detect, and provide signals as function of, light reflected from a surface of an active material layer on a charge collector backing layer moving on a roll-to-roll coated electrode manufacturing line. The particle detection unit also includes a controller configured to receive the signals from the detector and determine, in-situ and as a function of the signals from the detector, a foreign metallic particle on the active material layer. The controller is also configured to determine a position of the foreign metallic particle on the charge collector backing layer moving on the roll-to-roll coated electrode manufacturing line.
