Battery Insulating Layer Printing

Battery Insulating Layer Printing

Power Battery: Inkjet Printing vs. Traditional Blue Film

LION TEC Precision non-contact inkjet deposition of insulating layers for batteries, preventing short circuits, optimizing insulation uniformity, and enabling compatibility with low-temperature processes and flexible substrates.

Application Background

  • CTP/CTC battery technologies impose higher requirements on the shear resistance and mechanical strength of blue films for power batteries.

 

 

  • The 800V high-voltage electrical architecture of electric vehicles sets stricter standards for the resistance and ultra-high voltage breakdown resistance of battery blue films.

 

 

  • Improve the production cycle efficiency of insulating layers.

 

 

  • Superior protection strength enables batteries to achieve higher energy density.

Application Areas

  • Excellent insulation performance, ultra-high voltage breakdown resistance (>6000V for 80μm thickness)

 

 

  • Superior reliability and high mechanical strength

 

 

  • Precise inkjet thickness control at micrometer level

 

 

  • Simultaneous multi-surface printing & forming
