Apple is exploring a new technology called "electrically induced adhesive debonding" for iPhone batteries. This involves encasing the battery in metal instead of foil, allowing users to dislodge the battery from the chassis by administering a small jolt of electricity. This change aims to make battery replacements and repairs more convenient and is in response to the European Union's sustainability regulations.
Voltage-activated adhesives improve repair processes by allowing for quick and convenient electricity-fueled separation of components, reducing the need for high temperatures or physical contact with bonded parts. This method relies on adding ionic components into the adhesive mixture, making it responsive to electrical stimulation. As a result, voltage-activated debonding can reduce the risk of damage to internal components during repairs.
The E.U.'s targets for battery recycling by 2025 include introducing gradual targets for recycling efficiency, material recovery, and recycled content. All collected waste batteries will need to be recycled, and high levels of recovery must be achieved. Additionally, starting in 2027, consumers will be able to remove and replace portable batteries in electronic products at any time during the device's lifecycle.
