Apple Working on New Battery Tech for iPhones, Promises Faster Charging and Higher Capacity

Even though Apple normally signs external companies for manufacturing, it tries to do as much of the engineering and design in-house. And according to ETnews the company's latest research and development efforts are aimed toward the battery of the iPhone.

Apple is working on a new battery tech to boost endurance and charging speed

The report suggets Apple is experimenting with new materials for the cathodes - nickel, cobalt, manganese and aluminum. The new approach will also see the silicon content increase substantially. Silicon expands when it heats up during charging, but Apple has found a way to mitigate the issue.

The new cathode mix promises improved battery density (read higher capacity at the same volume) and faster charging. The tech giant will likely use carbon nanotubes (CNTs) to serve as conductive materials, which will further boost battery performance.

The same report claims that the first devices, likely iPhones, with the new battery tech, will launch as soon as 2025. This suggests that development is at a later stage and it's far from its infancy.
