While Apple normally outsources manufacturing to outside companies, it tries to do much of the engineering and design in-house. And second ETnews the company’s latest research and development efforts are aimed at the iPhone battery.
The report suggests that Apple is experimenting with new cathode materials: nickel, cobalt, manganese, and aluminum. The new approach will also see a substantial increase in silicon content. Silicon expands when it heats up during charging, but Apple has found a way to mitigate the problem.
The new cathode mix promises better battery density (read greater capacity for the same volume) and faster charging. The tech giant will likely use carbon nanotubes (CNTs) as conductive materials, which will further boost the battery’s performance.
The same report states that the first devices, probably iPhones, with the new battery technology, will be launched as early as 2025. This suggests that the development is at a later stage and is far from being in its infancy.
