The iPhone 17 series will be equipped with silicon-carbon negative electrode batteries

The battery life of iPhone has always been the biggest pain point for users, especially compared with Android flagships which now use silicon-carbon negative electrode batteries. 6000mAh is already commonplace, and there is even a 7000mAh level.

As it is “far behind”, Apple is also starting to fight back.

According to the latest news from the supply chain, Apple’s iPhone 17 series will be aligned with Android flagship phones, equipped with silicon-carbon negative electrode batteries, and the battery capacity will be increased to 5000mAh and above.

However, due to limited internal space, it is expected that only the iPhone 17 Pro Max model will be able to enjoy a battery of more than 5000mAh.

Compared with the previous generation, the iPhone 16 Pro Max only has a 4685mAh battery, which is a significant improvement and will refresh Apple’s longest battery life performance in history.

It is reported that the theoretical specific capacity of silicon is as high as 4200mAh/g, which is much higher than the 372mAh/g of traditional graphite negative electrode materials.

Therefore, silicon-carbon composite negative electrode materials can greatly improve the energy density of batteries, allowing the batteries to store more electricity at the same volume or weight.

In addition to having more power in the same volume, the silicon-carbon negative electrode enhances the thermal stability and structural integrity of the battery by introducing carbon material as a buffer matrix compared to the pure silicon negative electrode, reducing the safety risks of the battery under extreme conditions of use (such as high temperature, overcharging, over-discharging, etc.).
