Spray coating system from Venjakob replaces more cost-intensive film wrapping of battery cells:

This new process of coating and curing the battery cells with 100% UV lacquer in a single pass increases production speeds and reduces the comparatively high costs associated with the previous foiling process.

Technical challenges, golas and highlights at a glance:

• 6-sided coating of battery cells in different battery cell formats

• battery cell formats without retooling

• reliable all-round protection of the cell edges

• increased production speed

• paint recovery, reduced paint consumption

• no handling / turning / gripping

• no damage to the battery cells

Battery cell coating instead of foiling offers many advantages
Various analyses confirm the high effectiveness of the innovative insulating coating, which achieves adhesive strength values of over 15 MPa in tensile shear tests.
