Another Mobile Phone Will Use Silicon-based Anode!

Sources from the supply chain show that vivo will soon launch a blue ocean battery using a new generation of silicon-carbon anode material . Its energy density is about 20% higher than ordinary graphite anode batteries and about 16% higher than extreme graphite anode batteries. The battery will be equipped with vivo S19 series mobile phones and will be supplied by CATL.

In addition, many digital bloggers have recently revealed that upcoming flagship models such as iQOO 13 series, OPPO Find X8 series, OnePlus 13, Realme GT6 Pro, etc. will be equipped with ultra-large-capacity batteries of more than 6000mAh and silicon-based anode. The development of materials has added new impetus to the improvement of mobile phone battery life. Huawei, Xiaomi and other leading mobile phone manufacturers have launched corresponding models. Xiaomi 14 Ultra equipped with Jinshajiang battery uses the latest generation of silicon carbon anode technology, containing silicon to Up to 6%, the capacity has been increased to 5300mAh (the previous generation was 5000mAh), and the battery life has been increased by 17%.

"Charge in five minutes, talking for two hours", this classic mobile phone advertising slogan, the first half of the sentence highlights the fast charging performance, the second half of the sentence highlights the battery life performance, and the theoretical specific capacity of the silicon-based anode material can reach 4200mAh/g , while having high rate performance, is undoubtedly an ideal material to realize this vision.

However, silicon-based materials still have unresolved pain points such as large expansion coefficient and short cycle life. At the same time, the high price makes some low-end and mid-range models beyond reach. The current price of digital artificial graphite anode is only 65,000 yuan/ton (9,000USD) , while CVD silicon carbon The price of the anode is as high as 850,000 yuan/ton (11,700 USD). If the blending ratio is 3%, the cost will be 24,000 yuan/ton (3,314 USD) higher. In the future, as the technology improves and the cost decreases, more and more models will be used.
