Secondary battery film shape
and sealing thickness measuring

Lithium-ion secondary batteries, mainly used in portable devices,
are expanding their applications by lowering prices and further stabilizing
their performance through mass production and technology development
through product standardization. Moreover, with the full-fledged advent
of the electric vehicle era, it is emerging as a central axis of the eco-friendly
energy industry along with hydrogen batteries. With the expansion of use, stability due to explosion is emerging. As a result,
there is a need for a thickness measurement technology to strengthen
the sealing function and inspect the presence or absence
of internal air bubbles, which is the cause of the explosion. Nexensor's battery inspection solution has 20 times higher light volume
and higher measurement resolution than commercial products,
enabling high precision measurement of surface film thickness
when measuring thickness. In addition, its performance has been verified
by the on-site application.
