Xiaomi 11 Ultra Silicon-oxygen Anode Battery Technology
Xiaomi’s exploration of new batteries never stops. In today’s afternoon, Lei Jun again come forward for the Xiaomi 11 Ultra warm-up and announced that Xiaomi 11 Ultra will be the industry’s first super fast-charging silicon-oxygen anode battery, which can make the phone battery thinner and faster charging.
Silicon-oxygen anode (negative electrode) battery was previously mainly used in the new energy automotive industry, and Xiaomi is the world’s first time to apply the technology to cell phone products, through the negative electrode to increase the nanoscale silicon material, bringing 10 times the theoretical gram capacity of graphite.
It is reported that nowadays, the energy density of traditional graphite negative electrode battery is close to the theoretical limit (372mAh/g), it has been difficult to improve again, which limits the capacity of cell phone batteries, as well as the volume of thin and light cell phones, while the Silicon-oxygen anode technology can have a higher energy density, bringing greater battery capacity and higher fast charging.
Xiaomi said that the Xiaomi 11 Ultra model is also equipped with the second generation of silicon-oxygen anode battery technology, through the “silicon doped lithium” to achieve the silicon particles are not easy to pulverize, bringing 10 times the theoretical grams of capacity than graphite. At the same time, through the nano-silicon lithium treatment, overcome the previous generation of silicon-carbon anode battery first charge efficiency is low, and the battery cycle life is short two industry challenges.
Besides, Xiaomi also said that the Silicon-oxygen anode technology will be the future direction of battery technology, with the continued development of silicon-oxygen negative electrode batteries, cell phone batteries will become faster charging, lighter, and thinner, but also high-capacity characteristics.
Xiaomi 11 Ultra Silicon-oxygen Anode Battery Technology explanation
Xiaomi 11 Ultra’s first super-fast charging Silicon-oxygen anode battery wants to make the battery capacity larger, will inevitably be accompanied by the phone volume expansion. This is because the traditional graphite negative electrode battery energy density is close to the theoretical limit, it is difficult to further improve. But Xiaomi never stops exploring new battery materials, Xiaomi had the first attempt at Silicon-oxygen anode battery technology on the MIX Alpha. Today, Xiaomi 11 Ultra debuts a super-fast charging Silicon-oxygen anode battery with higher battery energy density! Larger capacity! Faster charging!
The first super-fast charging silicon-oxygen cathode battery “silicon doped lithium” the second generation of silicon-oxygen cathode battery by “silicon doped lithium” in the battery cathode increased the nanoscale silicon-oxygen compound so that the silicon particles are not easy to break the powder, bringing theoretical 10 times the ion storage capacity of the traditional graphite material. By doping the silicon with lithium, the previous generation silicon-carbon anode battery has overcome the two industry challenges of low first charge efficiency and short battery cycle life.
Xiaomi 11 Ultra 4 with the continued development of silicon-oxygen negative battery, cell phone batteries will become faster charging, thinner and lighter, and both high-capacity characteristics, which will be the future development direction of battery technology.
It is worth mentioning that, from the current official information, Xiaomi 11 Ultra, in addition to the super-fast charging Silicon-oxygen anode battery, will also bring several heavyweight innovation technologies such as liquid lens on Mi Mix, Surging Chip, the machine is the perfect display of Xiaomi’s technical strength, very much anticipated.
