Battery Cell Coating
What are battery cell coating?
In the context of Light weighting, CTC/CTP battery structure technology has been derived. Under the demand of fast energy replenishment, the electrical safety of high-voltage battery makes it necessary to have higher cover age of cell insulation layer. The traditional PE Tape has been difficult to meet the new structure of high-strength bonding between cells, and the shaped structure at the electrode also restricts the application of PE Tape.
New structures require new materials. UV insulating coatings are worthy of your attention for their superior reliability and process flexibility, in addition to making up for the shortcomings of traditional PE Tape.


For Battery Cell Uv Coating
Application: Battery cell coating

In the automotive EV and new energy industries, various power devices require electrical isolation to ensure safe and reliable operation in different applications. Electrical isolation is essential to prevent current leakage.
Product Features of battery cell coating
