Pressure measurements are critical inspection steps for Lithium-ion battery production to ensure product quality.
Fujifilm's Prescale pressure measurement film is used in several applications, including roller condition check for electrode pressing, welding horn contact pressure adjustment, and checking the swelling level of the battery.
This does not only support daily production quality stability but also improves overall LiB quality, service life, capacity improvement, and miniaturization.
Below are some Prescale pressure measurement applications for the Lithium-ion battery manufacturing process.

Electrode process
Process Examples:
-Coating positive electrodes and negative electrode on an aluminum or copper core.
-Calendaring the positive electrodes and negative electrodes continuously to increase its density.
-Slitting positive electrodes and negative electrodes to desired width.
-Transporting electrodes to the next process.
Benefits of Prescale:
-Prevents dimensional errors and ensures accurate coating and pressure
or promotes accurate slitting.
Process Examples:
-Calendaring the positive electrodes and negative electrodes continuously to increase its density.
-Transporting electrodes to the next process.
Benefits of Prescale:
-Prevents thickness variation of the electrode.
Assembly process
Process Examples:
-Welding TAB to electrodes by ultrasonic welding machine.
-Sealing laminate film of the cell.
Benefits of Prescale:
-Verify that the TAB is securely welded to the electrode.
-Prevents welding defects that cause leakage.
Aging process
Process Examples:
-Charge or discharge the cell to have comprehensive inspection.
Benefits of Prescale:
-Visualize the load applied to the LiB to see its energy performance.
-Facilitate pressure adjustment to avoid damage or deformation.
