6000 mAh silicon negative battery! Xiaomi 15Pro upgrade leaked again

On July 23, blogger Digital Chat Station broke the news that the battery capacity of Xiaomi Mi 15 Pro has been increased to 6000mAh and supports 90W wired flash charging. This will be the Pro model with the largest battery in Xiaomi’s digital series.

Digital chat sites previously revealed that the Xiaomi Mi 15 Pro battery has ultra-high energy density and a much higher silicon content than competing products.

After large-scale testing of silicon-based batteries in 2023, second-generation silicon anode batteries have been identified as the future development direction of the industry. This year will usher in the peak of direct competition.

1. The theoretical gram capacity of silicon can reach 4200 mAh/g, which is more than 10 times that of graphite (the theoretical gram capacity of graphite is 372 mAh/g).

2. For the negative electrode, the capacity when the lithium ion insertion amount reaches the maximum is the theoretical gram capacity, which means that under the same weight, the capacity of the silicon negative electrode battery is greater.
3. While maintaining a high gram capacity, silicon anode batteries can also meet the rate performance requirements required for fast charging. With this advantage, Xiaomi Mi 15 Pro maintains a thin and light design while packing a large 6000 mAh battery.

   

   Core configuration
4. Xiaomi 15 Pro uses a full depth 2K screen.
5. Powered by Qualcomm Snapdragon 8 Gen4 mobile platform.
6. Coming out in October.
7. Using a single-point ultrasonic under-screen fingerprint sensor to support wet-hand unlocking.

Editor’s review

The Pro version of Xiaomi’s digital flagship series has always been tepid. This time Xiaomi 15 Pro is expected to break this dilemma. In the current development direction of increasing battery energy density and pursuing continuous reduction in size, the biggest highlight of Xiaomi Mi 15 Pro this time is the obvious improvement in the silicon anode battery. The upgrade to a 6000 mAh battery version should be an upgrade that will surprise users. .

The above is the detailed content of 6000 mAh silicon negative battery! Xiaomi 15Pro upgrade leaked again. For more information, please follow other related articles on the PHP Chinese website!
