A lithium battery pole thickness measurement system based on laser displacement sensor

As the main component of lithium-ion battery components, the size of the thickness of lithium-ion battery pole piece, directly impact on the conductive efficiency and space utilization of the battery. In the rolling production process of lithium-ion battery pole piece, it requires real-time detection of changes in the thickness of a pole piece. In this paper, it combined with the characteristics of the lithium-ion battery pole thickness after rolling, and through the analysis of the current thickness measurement method, developed the measurement system of lithium-ion battery pole thickness which is based on laser displacement sensor.
