Energy storage battery double-sided adhesive

Why do EV batteries need adhesives?

An essential contribution of adhesives to EV battery design is that they allow for greater simplicity. For example, adhesives help reduce or eliminate mechanical fasteners, reducing battery complexity. Some formulations eliminate the need for primer, reducing the materials needed in production and VOCs associated with primer use.

What is a battery adhesive?

Courtesy of Dupont. Some adhesives for battery assembly serve a multifunctional role, providing structural joining, thermal management, and support for dielectric isolation. Adhesives in this class offer thermal management and medium strength that supports the stiffness and mechanical performance of the battery pack.

How can a PET film protect a battery from dielectric breakdown?

For the electrical insulation of sensitive battery components and effective protection against dielectric breakdown, Lohmann offers various single- or double-sided PET films. They can be applied to metal parts of the battery, e.g., on side panels, cell housing or battery case components.

Are EV batteries thermally conductive?

Thermally conductive adhesives, sealants, and gap fillers are critical in EV battery thermal management and safety. Battery cell, module, and pack designers should be aware that traditional silicone-based thermal gap fillers may cause contamination that can result in contact failure.

Why should you use multifunctional tape in the battery manufacturing process?

Using multifunctional tape solutions in the battery manufacturing process combines multiple benefits: They offer immediate and strong adhesion and thus fast handling and add functionality in just one product.

What are the advantages of double sided tapes?

nd provide a thermal conductivity of up to 2 W/mK.the heat management inside the EV battery and help keeping the lithium-ion between 20 and 35 °C in order to enable the longest possible lifetime double-sided tapes are free of solvents, halogens and silicones and protection of el
