The Chinese technology giant Xiaomi has just anticipated one of the features that we will find on board the Xiaomi Mi 11 Ultra, it is the first ultra-fast charging silicon-oxygen anode battery, which should make smartphone batteries more thin and quick to refill.
Xiaomi Mi 11 Ultra will be the first smartphone in the world with a silicon-oxygen anode battery
Until now, silicon-oxygen anode batteries have been mainly used in the automotive industry (electric cars), Xiaomi will therefore be the first brand in the world to use this technology on its mobile products. This will be done by adding nanoscale silicon materials across the anode, bringing 10 times the theoretical capacity compared to graphite per gram.
At the moment, the energy density of traditional graphite anode batteries is close to the theoretical limit of 372 mAh / g and it is difficult to increase it further. This limits the battery capacity of our smartphones, especially if you want to keep them light and thin. While the technology with silicon oxide anodes can bring a higher energy density, therefore a greater battery capacity and a more performing fast charging.
Xiaomi has said that the upcoming Xiaomi 11 Ultra will be equipped with a second generation silicon-oxygen anode battery. Through the "doping of silicon to supplement lithium", the silicon particles are not easy to pulverize, bringing 10 times the theoretical capacity of graphite.
At the same time, replenishing lithium with nano-silicon overcomes the two industry problems of the previous generation of silicon-carbon anode batteries, low charging efficiency and short battery cycle life.
In addition, Xiaomi also said that the silicon-oxygen anode technology will be the future development direction of battery technology. With the continued development of silicon-oxygen anode batteries, smartphone batteries will become faster, lighter and thinner.
It is worth mentioning that from the current official information, in addition to the super fast-charging silicon-oxygen anode battery, Xiaomi Mi 11 Ultra will also bring a number of important innovations such as lenses liquid.
More information will be announced at the launch of the smartphone, which is March 29, 2021.
The Mi10 phone works very badly, it keeps crashing despite updating from an authorized center, careless purchase and wasted money. Never again Xiaomi
