Apple’s foldable smartphone will be equipped with silicon-carbon(Si -C) anode lithium-ion battery.
It is reported that Apple’s foldable screen mobile phone will be equipped with two silicon-carbon(Si-C) anode batteries, the battery cells use 3D stacking technology, and the capacity is 5000mAh or more, the exclusive supplier of this battery is ATL.
Silicon-carbon Si-C anode material for Apple foldable screen new smart phone that will be launched 2026
Compouding silicon-carbon（Si-C) anode
Suppliers in Apple’s foldable mobile phone supply chain have been busy carrying out preliminary preparations for the Apple foldable mobile phone to be launched in 2026.
Apple’s foldable phone will use two ultra-thin silicon-carbon（Si-C) anode batteries in the core battery configuration, with a single capacity of about 5000mAh. Silicon-carbon （Si-C) anode batteries are made by precisely compounding silicon and carbon materials as anode materials.
Among them, carbon materials usually act as structural supports or auxiliary components, forming various structures with silicon such as silicon-carbon alloys, silicon-coated carbon, and carbon-coated silicon, effectively improving the volume expansion problem of silicon materials during the charging and discharging process, and greatly improving the battery’s cycle stability and C-rate performance.
Significant advantages of silicon-carbon anode materials in lithium batteries:
- High energy density: The specific capacity of silicon-carbon anode is as high as 4200mAh/g, which is much higher than that of traditional graphite materials. The capacity of silicon-carbon composite materials can reach 1500-2000mAh/g, which can significantly improve the energy density of the battery.
- Excellent cycle performance: Through advanced manufacturing processes, the cycle life of silicon-carbon anodes can be significantly improved to more than 1,500 cycles, far exceeding graphite anodes.
- Fast charging capability: Silicon-carbon materials allow lithium ions to be inserted/deinserted at high speeds, so silicon-carbon anode batteries can be quickly charged to meet the needs of modern electric vehicles and mobile devices.
- Safety performance: Silicon-carbon anode materials have low expansion rates and good structural stability, so they are not prone to short circuits or fires, which can improve battery safety.
- Cost-effectiveness: Although the production cost of silicon-carbon anodes is high, due to their high energy density and excellent comprehensive performance, their comprehensive cost-effectiveness is high. With the iteration of technology and large-scale production, the cost of silicon-carbon anodes will be further reduced.
These advantages make silicon-carbon anode an important direction for the development of lithium-ion battery technology in the future, especially in terms of improving battery energy density and improving battery performance.
Before the launch of Apple’s folding screen mobile phone, Apple’s upcoming iPhone 17 series this year will also be equipped with this type of battery.
For a long time, Apple smartphones have been plagued by poor battery runtime. This time, the silicon-carbon anode battery is expected to change this situation in one fell swoop.
In fact, ATL has already supplied silicon-carbon anode batteries for other Chinese brands of mobile phones.
