Battery electrode thickness measurement
Two laser sensors on both sides of the web measure electrode thickness continuously and without contact on the coating line.
The problem
Coating thickness variation reduces cell capacity.
Conditions
Web moving at 60 m/min.
The method
Differential measurement with two optoNCDT 1900 sensors on a dataCONTROL C4 controller.
The result
Verified: ±1 µm repeatability on the customer line.
