Foil Coatings and Laminates for Battery Applications

DUNMORE Primed Current Collector

Dunmore applies precision coatings to foil substrates to add a number of functionalities to battery components. Whether you are looking for a manufacturer of primed foil / primed current collector, or battery pouches for fuel cells and lithium ion batteries, Dunmore can meet your needs. Functional foil coatings include:

  • Primer coatings
    • Carbon black primer for primed current collector
    • Conductive primer
  • Adhesion promoters / Electro adhesion coating
  • Corrosion resistant coatings

Dunmore’s carbon primer coatings for thin foils such as aluminum foil play an important role in the construction and performance of your battery design. Using precision coating techniques to produce conductive coated aluminum foil gives optimal performance to your battery technology as you introduce different electrode materials to the lithium ion battery construction.

Carbon Coated Aluminum Foil

Dunmore provides carbon coated aluminum foil products for your lithium ion battery design. Using carbon coated aluminum foil provides better mechanical strength and helps prevent short circuits in the finished product. It also improves adhesion with your electrode material. It allows you to use better performing electrode materials while negating issues related to adhesion with the current collector layer.

Battery Component Converting Capabilities

Dunmore’s contract manufacturing services can service your commercialization needs, or provide R&D support during the design phase of your project. Dunmore can coat, laminate, and slit aluminum foil, copper foil, stainless steel foil, and other foils. The organization has a history of successfully processing thin foils and thin films that are often difficult to handle.

Dunmore’s carbon coated aluminum foil capabilities include:

  • Dual side coating
  • Lane coating
  • From .36 mil – 8 mil foil thickness
  • Annealed (soft) through H19 temper foils
  • 14" - 60" wide
  • Drying to 350°F
  • Roll diameter up to 32”, weights to 2000 lbs

Flexible Battery Packaging Material Solutions

In addition to providing carbon coated foil for Lithium-ion batteries, Dunmore has the capabilities to produce battery packaging material for thin film lithium batteries and flexible printed batteries. There are a number of different flexible substrates that can be used to ensure your flexible battery is fully encapsulated and keeps its integrity. Common battery packaging material includes aluminum laminated film, metallized film, and other flexible polymer substrates.

Dunmore looks forward to speaking with you about your flexible battery design, and working with you to produce the right battery packaging material. Whether you are looking to produce an aluminum laminated film or barrier coated flexible substrate, we can provide the materials and chemistry expertise to help you develop your flexible battery product. Our history of chemical formulating has produced a broad portfolio of heat sealable adhesive options, which will be critical in producing a robust flexible battery.

Dunmore has extensive knowledge with a variety of flexible polymer substrate, encapsulation film, and other flexible substrates. The design and production of the right barrier film or encapsulation film using high performance flexible substrates will be crucial to ensure you achieve the stringent WVTR requirements.
