Xiaomi promises 1h40 more autonomy with batteries of the same size

Xiaomi would have found a way to improve the autonomy of our smartphones. The manufacturer claims to be able to increase the capacity of the batteries by 10% for the same size.

Without finding a new battery technology to significantly increase the autonomy of our electronic devices, manufacturers have been working for several years to accelerate their charge. In a few years, our smartphones have gone from 5 or 7 W chargers to 22, 30, 65 or even 120 watt chargers at best. However, Xiaomi seems to want to change things.

A lithium battery with high silicon content

In a recent post Weibo, the Chinese manufacturer presented its new High-Silicon battery technology. Don’t expect a big revolution, this is still a lithium-ion battery, but this improved format could be very interesting if it delivers on its promises.

Xiaomi indicates that it has tripled the amount of silicon at the anode (the negative electrode) of the battery and has developed a new format to reduce the battery control circuit. In addition, the set is coupled with a new artificial intelligence algorithm for energy management.

Result: Xiaomi would have managed, according to their statements, to create a battery with a capacity 10% greater than current technologies for an identical size. According to their statements, this represents 100 more minutes of autonomy for our smartphones, or 1h40.

Production in 2022

Xiaomi indicates that the mass production of these batteries will begin in the second half of 2022. So we should not expect this technology to be integrated in the Xiaomi 12, but in the next generation.

However, one question remains unanswered. Silicon anodes for lithium-ion batteries are nothing new, but this technology has been sidelined due to life issues. Has Xiaomi managed to resolve this drastic loss of capacity concern over time? We will have to wait for a more complete presentation, or even the first tests of the device, to find out.
