Apple has been producing an increasing number of its own parts internally; according to a recent rumor, batteries may soon be added to the list of components that Apple creates in-house. Furthermore, the batteries may end up in Apple devices as early as the next year.
According to industry insiders cited by the Korean website ETNews (via MacRumors), Apple has been developing its own batteries at least since 2018, when the iPhone manufacturer started employing individuals with prior battery-related experience and submitting applications for relevant patents.
According to ETNews, Apple is now assembling cathode materials to assess performance in order to produce a "completely new" battery with significantly better performance.
It appears that the composition of the Apple battery differs greatly from that of other batteries on the market. For better performance, it mixes basic components such aluminum, manganese, nickel, and cobalt.
According to reports, the corporation is also looking into using silicon content as a cathode material instead of the more common graphite. However, ETNews reports that Apple is aiming to address silicon's issue with volume increase when charging and discharging.
Furthermore, according to reports, Apple is investigating carbon nanotubes for their potential to increase conductivity, which would allow for higher performance from materials that are less prevalent. Faster charging times might also result from that switch.
The end product, the battery, is expected to be a breakthrough that hasn't been released into the market yet. According to a source who spoke with ETNews, Apple's requirement for high-performance batteries surged dramatically with the release of the Vision Pro headset. The $3,500 device has a battery life rating of about two to 2.5 hours. While competing smartwatches now last many days on a single charge, gadgets like the Apple Watch have maintained the same "all-day" rating since their launch.
The ETNews article doesn't specify Apple's current progress on these batteries or what kinds of performance gains have been found during testing.
The majority of batteries are lithium-ion, consisting of an electrolyte layer, cathode, and an anode. Typically, graphite is used for the cathode and lithium metals for the anode. Reliance Digital claims that because "Li-ion" batteries have a greater capacity while taking up less space within a device, they are found in the majority of smartphones.
Generally speaking, the industry has experienced a major increase in battery performance in recent years, either as a result of software managing operating systems and batteries or physical engineering techniques such chipset power efficiency.
Furthermore, Apple is not the only business developing better batteries. OnePlus unveiled the "glacier battery" during the summer, claiming to be able to fit a 6,100 mAh battery cell into a 5,000 mAh slot. According to reports, that battery, which uses silicon carbon anode technology, can run for two days on a single charge.
Other businesses, like as Realme, have been advancing charging technology. A 320W charger that the business just unveiled is meant to be able to fully charge a smartphone battery in less than five minutes. That charger isn't compatible with any real devices yet.
Apple allegedly co-developed its battery project in addition to its now-canceled attempt at an Apple Car. Subsequently, the emphasis turned to mobile applications. If rumors are to be trusted, Apple batteries ought to be appearing in their devices by 2025.
We anticipate the new battery will be available in the iPhone 17 series if it is released next year.
