Apple is reportedly exploring the development of pure silicon batteries for its iPhones, a move that could significantly enhance battery performance and longevity. In a bid to revolutionise its battery technology, Apple is working on integrating pure silicon batteries into its iPhones. This initiative aims to replace the traditional graphite anodes with silicon, which could potentially offer higher energy density and faster charging times.

However, the transition to silicon anodes is not without its challenges. Silicon tends to expand during charging cycles, which can lead to structural issues within the battery. To address this, Apple is collaborating with manufacturers to develop solutions that can accommodate the expansion and ensure the durability of the batteries.
