According to a report by Kuai Keji on July 1st， a blogger known as “Digital Chat Station” has hinted that Redmi’s upcoming high-performance smartphone is currently undergoing testing with an impressive 8000mAh-class ultra-large battery. This would mark the largest battery capacity for any Xiaomi-branded device.
It is understood that Redmi’s high-performance product lines include the Turbo series and the Ultimate series. This suggests that the Redmi device with an 8000mAh battery could either be the K90 Ultimate Edition or the Turbo 5 Pro.
Currently， Redmi’s high-performance models have already surpassed the 7000mAh mark， with the Turbo 4 Pro released in the first half of the year featuring a 7550mAh battery.
Since last year， the Android camp has been actively competing in terms of battery capacity. This trend is significantly driven by the widespread commercialization of silicon-carbon anode battery technology. Compared to traditional lithium batteries， silicon-carbon anode batteries offer a higher energy density， allowing for more power storage within a similar physical volume.
The principle behind silicon-carbon anode battery technology is primarily based on the high theoretical specific capacity of silicon materials and their unique alloying lithium storage mechanism. Silicon reacts with lithium to form alloys， achieving a theoretical specific capacity of up to 4200mAh/g， which is considerably higher than the 372mAh/g of traditional graphite materials. This enhanced capacity directly translates to longer usage times for devices.
Furthermore， silicon-carbon anode batteries exhibit enhanced safety performance. Their lower lithium deintercalation potential helps to prevent lithium dendrite formation on the surface during charging， thereby reducing the risk of internal short circuits and improving overall battery safety.
