Quick guide
Apple plans to make iPhone batteries user-replaceable by 2027, considering replacing traditional adhesives with electrical adhesion technology. This technique involves encapsulating the battery in a metal that achieves permanent adhesion by applying a low-voltage DC current. Tesa has commercialized electrical adhesion technology, introducing "debonding on demand" products that allow for easy disassembly of components by applying pressure and DC voltage. Electrical adhesion technology is not only suitable for consumer electronics, but also for creating strong bonds between a variety of materials such as biological tissues, graphite, and metals, showing potential in robotics and medicine, among other fields. The convenience and efficiency of this technology bodes well for a bright future in simplifying complex tasks across industries.
Apple's step towards a replaceable iPhone battery
In response to the European Union's advocacy to increase the serviceability of consumer electronics, such as smartphones, Apple has been forced to make the iPhone's battery replaceable by users by 2027. To achieve this, Apple is considering replacing traditional adhesives with electroadhesive technology, which typically requires heat, isopropyl alcohol, or force to separate. The proposed method involves encapsulating the battery in a metal to form a cation/anion pair with the metal shell, ensuring permanent adhesion by a low-voltage DC current application.
Commercialization of electroadhesive technology by Tesa Corporation
The concept of device disassembly utilizing electrical adhesion is not entirely new, and Tesa has already introduced this concept in the form of its "debonding on demand" product, which is designed for electrolytic bonding. The method involves applying a special tape on one side of the metal surface, applying a pressure of 5 bar for 5 seconds. Subsequently, by applying a 12V DC voltage for 60 seconds, the components can be easily removed without leaving any residue and without applying force.
The potential of electroadhesive technology in various industries
The broad applicability of electrical adhesion technology for adhesion is not limited to consumer electronics. Its ability to create strong bonds between a variety of materials, such as biological tissues, graphite, and metals, presents fascinating possibilities in fields such as robotics and medicine. The convenience and efficiency offered by electrical adhesion technology in terms of disassembly, as seen in the context of smartphone battery replacement, bodes well for the bright future of this technology in simplifying complex tasks in various industries.
