The battery of Redmi's high-performance new phone has exceeded 8000mAh! The biggest in Xiaomi's history!

　　Recently, the blogger's digital chat station revealed that REDMI is testing a high-performance phone equipped with an 8000mAh super large battery, which will become the model with the largest battery capacity under Xiaomi. It is understood that REDMI's high-performance product series includes the Turbo series and the Supreme series, so the model equipped with an 8000mAh battery may be the K90 Supreme Edition or the Turbo 5 Pro.

At present, REDMI's high-performance model has exceeded the upper limit of 7000mAh battery, and the Turbo 4 Pro launched in the first half of the year is equipped with a 7550mAh battery. Since last year, the Android camp has increased its battery capacity, thanks to the widespread application of silicon-carbon negative electrode batteries. Compared with traditional lithium batteries, silicon carbon anode batteries have higher energy density.

The principle of silicon carbon negative electrode battery is mainly based on the high theoretical specific capacity of silicon materials and its unique alloyed lithium storage mechanism. Silicon reacts with lithium to form an alloy, with a theoretical specific capacity of up to 4200mAh/g, which is much higher than the 372mAh/g of traditional graphite materials.

　　In addition, silicon-carbon negative electrode batteries also have higher safety. Due to the low deintercalation lithium potential, lithium evolution phenomenon during charging can be effectively avoided, thereby reducing the risk of battery short circuit.
