Apple’s work on improving its batteries for the iPhone to come in 2025
A new report claimed that Apple is developing battery technology in-house, with a goal of making it commercially available in its products by 2025.
Korean business newspaper ETNews reported that Apple is coming up with a completely new battery with “significantly improved performance compared to the existing one”.
For one, the material mix in its existing cathodes (nickel, cobalt, manganese, and aluminium) will see a new composition, with different amounts of raw materials.
A possible new conductive material used is carbon nanotubes (CNTs), which will act as a more effective conductive material.
The anode’s silicon content would also “dramatically increase”, taking over its graphite base to offer more charge with the same volume, on top of increasing charging speeds. Silicon is known to expand during charging, and ETNews assumes that Apple has figured out how to prevent that.
The report further said that Apple’s self-development of batteries has been ongoing since 2018, with an ex-Samsung SDI (Samsung’s battery development company) put in charge of Apple’s battery development. It also said that the “main target” of the new battery technology is “mobile”, which we interpret to be iPhones (although not necessarily limited to them).
