Technology Comparison
Inter-cell insulation materials are critical for battery safety. They effectively prevent short circuits, block single-cell failure spread, and are essential for improving overall safety, stability and service life.
Traditional PET Insulation Film Technology
As a traditional cell insulation material, PET insulation film isolates the impact of single-cell failures on adjacent cells. However, with a thickness of only 0.015-0.20 mm, it is prone to defects during production, affecting appearance and performance. Traditional processes still need optimization.
- Prone to scratches and peeling due to poor lamination
- Easy overlapping at edges, resulting in poor dimensional consistency
- Average voltage resistance/insulation performance
- Average adhesion/durability
- Manual edge treatment increases damage risk and electrolyte leakage
Precision Industrial Coating Technology
Independently developed by Rocktin, precision industrial coating enables large-area, high-speed and accurate coating. AI image recognition precisely avoids non-spray areas, with no splash or pollution. It supports multi-sided simultaneous spraying and high-viscosity materials, fully superior to traditional PET insulation film processes.
- Innovative side-spray technology | Solves uneven lamination and edge overlapping
- Efficient film-forming process | Solves uneven thickness and scratches
- Splash-free process | Solves residue and secondary pollution
- Ultra-fast coating & curing | Solves low efficiency and manual errors
- Special high-viscosity materials | Solves peeling and aging
- Excellent material performance | Solves insufficient insulation/chemical resistance
