Do energy storage batteries need adhesive film

How do I choose the best adhesive film for a battery pack?

The type of battery cells: Adhesive films must be suitable for the type of battery cells used in the battery pack (material, size and shape). The operating conditions: Adhesive films must be suitable for the operating conditions of the battery pack, e.g. temperature and humidity.

Can adhesives be used in EV battery packs?

During The Battery Show North America, Battery Technology spoke with Frank Billotto, Dupont ’s Business Development Manager for EVs. In this article, we'll delve into how adhesives can be utilized in EV battery packs and gain insights into how they enhance performance, as he explained.

What are battery adhesives and how do they work?

According to Billotto, these adhesive materials act as interfaces between the battery cells and the cooling plates, ensuring heat is efficiently dissipated during charging and discharging. These adhesives enhance battery longevity by helping keep the batteries within the optimal temperature range (typically 35-60°C).

Why do electric vehicle batteries need adhesives & sealants?

These adhesives keep the cells firmly in place throughout the vehicle's lifespan. Adhesive technology plays a vital role in the assembly and performance of electric vehicle battery packs. From ensuring structural integrity to managing heat and enhancing safety, adhesives, and sealants contribute significantly to the success of EVs.

What is a double sided adhesive film used for?

Fixing electronic circuits: (double-sided) adhesive films are used to implement electrical circuits in battery packs. This can be, for example, the BMS (Battery Management System) for controlling the charging and discharging process of the battery cells.

Why do EV batteries need ribbon bonding?

Billotto emphasized that ribbon bonding facilitates the efficient transfer of heat from the batteries into the cooling system, all while providing structural support. Dupont’s BETAMATE (5) and BETAFORCE (7) are part of a broad portfolio of adhesives for numerous EV applications.
