ZTE Snapdragon 8 Gen 3 series reveals new look, three models use silicon carbon negative electrode battery for the first time

November 21 news, recently exposed news shows that ZTE’s upcoming Snapdragon 8 Gen 3 The new series of phones introduce silicon carbon anode battery technology, including three models: 5500mAh 165W, 6000mAh 80W, and 6500mAh 80W.

According to blogger @digitalchatstation, the upcoming Red Magic 9 Pro mobile phone will be equipped with a 6500mAh battery and support 80W fast charging, while the Red Magic 9 Pro The model uses a 5500mAh battery and supports 165W fast charging. According to netizens’ speculation, the remaining 6000mAh 80W version may be the upcoming Nubia Z60 Ultra mobile phone, it is reported that the machine will be officially unveiled next month.

Silicon carbon anode battery technology may be relatively unfamiliar to most people. However, the Honor Magic 5, Huawei P60 Art, and Xiaomi MIX Fold released this year Many flagship models such as 3 have already adopted this technology. The introduction of this technology allows the battery capacity of mobile phones to be significantly increased while maintaining a thin balance of body.

It is understood that the energy density of traditional graphite anode materials is approximately 372mAh/g, while the theoretical energy density of pure silicon anode materials can reach 4200mAh/g, which is the highest energy density of graphite anode materials. 10 times as much. However, the silicon anode expands during charging and discharging, and the expansion volume can be as high as 300%. In order to solve this problem, the silicon-carbon anode battery adopts a carbon wrapping method, which effectively alleviates the problem of silicon anode expansion

Although the current silicon-carbon anode battery technology is still in the early stage of commercialization, as more manufacturers develop Research investment is expected to lead to better development prospects in the future.
