Adhesive tape solutions for electrode fixing applications

Avery Dennison offers fixing tapes that are used to bind multilayer electrode constructions consisting of current collector foils, anode and cathode materials, and separator films in EV battery cells.

Pressure-sensitive adhesives for binding of multilayer electrode fixing constructions

Avery Dennison electrode fixing tape solutions — offered with polyethylene terephthalate (PET) and polypropylene (PP) plastic facestocks — are easily visible, compatible with battery materials, and do not contribute to unintentional self-discharge.

These tapes offer key features and benefits, including:

Polypropylene facestock is chemically inert to prevent self-discharge due to DMT redox shuttle
Green color for visible indication of application
Electrolyte-compatible acrylic adhesive
Self-wound, linerless construction with various widths available on plastic cores
Made in USA for Inflation Reduction Act compliance

Key benefits

Self wound clear facestock with green adhesive for application indication
Excellent prolonged resistance to electrolyte at elevated temperature
Polypropylene facestock provides inertness for best electrolyte compatibility to reduce potential of self discharging driven by DMT redux shuttle
Dielectric facestock provides electrical insulation (4.5 kV AC Breakdown Voltage)

ES 1281

ES 1281 is a 1 mil clear polyester single coated tape with a highly transparent film that features excellent tear strength, heat resistance, dimensional stability and chemical resistance. The tape’s adhesive is a green pigmented acrylic with electrolyte resistance/compatibility. This product is intended for electrode fixing in batteries by wrapping around the separator film and back onto itself.
