According to a source, Apple is working on a bespoke battery design built in-house. The iPhone maker is claimed to be aiming to improve product battery life by modifying the chemistry of its batteries. According to South Korean news outlet ET News, Apple's reported battery technology advancements are likely to make their way into the company's products for the next couple of years, implying that development of the purported battery enhancements is pretty close.
Apple is developing enhanced battery technology
According to the report (in Korean), Apple is developing enhanced battery technology for the following products, including a "next-generation battery" (translated from Korean). According to reports, the corporation is directly involved in the design of the new technology, from the development of the cathode and the essential components and materials to the usage of alternative materials for more remarkable performance.
Apple is contemplating a new cathode material composition, as well as the usage of carbon nanotubes (CNTs) as a conductive material - both of which could offer increased performance over the company's current battery components.
The company is also experimenting with employing other materials for the anode material used in the battery. Apple is claimed to be exploring utilising silicon instead of graphite, despite silicon's tendency to expand while charging or discharging, because the company has identified a means to alleviate the expansion issue.
According to reports, the corporation has been working on the technology since at least 2018, including the hiring of an executive from Samsung SDI, the South Korean firm's battery and electronics section, a year later.
Conclusion
While Apple hasn't said when we can expect to see the alleged battery improvements or which devices will be equipped with the next-generation battery design, the report claims that Apple is looking to launch devices with the new battery technology within the next two years, which means we could see devices with improved battery life over their predecessors as early as 2025.
