Battery mounting

For more performance and safety.

Battery mounting has a special role to play in today’s development of new devices: performance of the battery is supposed to improve leading to heavier batteries with every new generation, while designs should remain thin to enable a contemporary, flat design of mobile devices or to enable completely new concepts such as foldable devices.

Regulations such as the EU Battery Directive and increased interest of end customers in sustainable solutions push manufacturers to ensure the reparability and recyclability of their devices, which make removable batteries mandatory. The right adhesive tape solutions can overcome these challenges and open up completely new design possibilities.

Requirements for adhesive battery mounting solutions

High and reliable adhesion combined with the ability to reduce shock and shifting is the best way to avoid the risk of battery damage. Depending on the method of battery mounting, the tapes must also have very good removability to ensure that the battery can be detached easily and safely. The availability of a wide range of different tape thicknesses gives you more freedom and flexibility in the design of this component, thus enabling larger batteries with more power.

Adhesive solutions for all battery mounting methods

Battery mounting
The battery is wrapped and bonded to a PET film. This film is then bonded to the housing by using an adhesive tape with a high bonding performance. If needed, the battery can be easily removed from the wrapping film and thus from the housing. Thinner tapes are often required due to the multilayer design.
Along with efficiency aspects, high bonding power and a good impact resistance are the key properties for permanent battery mounting. This method allows very thin designs. The battery removal process, on the other hand, is comparatively complex, as either low or high temperatures are required to release the bond.
The battery with the die-cut already attached is mounted into the housing. By stretching the tape the battery can be removed very easy and residue-free. High tear resistance and low removing force are critical for this detaching method, but it allows complex battery designs.
Solvent removal
The tape is bonded to the battery, which is then attached into the housing. Critical for this method is a high initial bonding performance of the tapes, but a big decrease of the bonding power after applying solvents, so that the battery can be detached easily. This method allows thin designs.
