Battery electrode thickness measurement

Two laser sensors on both sides of the web measure electrode thickness continuously and without contact on the coating line.

Micro-Epsilon optoNCDT laser sensors

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.
