Why do EV batteries need to be sealed?

Effective battery sealing is the foundation for best-in-class battery performance. Without a reliable seal, all of the technology and range advancements a manufacturer can marshal will ultimately fail. Henkel has the practical know-how and the capable portfolio to help make the next generation of EV batteries succeed.

What is a battery seal?

A battery seal is a safety device that tightly seals a battery to prevent the loss of electrolytes. It is sealed to the cell by means of radial crimping pressure or by impact.

What is the purpose of a sealed battery?

The purpose of a sealed battery is to reduce or eliminate the gassing during charging and discharging of the battery reaction, so that water loss does not occur from the electrolyte. The potential difference (emf) of any reaction can be readily calculated from the concept of a sealed battery.

What is a battery pack seal?

While thermal and electrically conductive materials often get the limelight, battery pack seals do the heavy work of protecting the battery components from intrusion by moisture, dust, and other debris.

What is battery pack perimeter sealing?

Battery pack perimeter sealing applications are just one element in a wider group of advanced materials, such as adhesives, thermal interface materials, and battery safety materials that work in concert to shield and protect the entire symphony of vital EV components.

Does Henkel seal a battery?

Battery sealing and battery safety go hand in hand. Henkel’s high-performance sealers guard the battery pack interior by working in conjunction with – or in place of – conventional fasteners to create a continuous, robust barrier against contamination.
