IT House reported on July 1 that Xiaomi today officially announced Xiaomi’s self-developed “Paper G1” battery management chip, and stated that this chip will be released at 7 pm on July 4 and will be installed in the Xiaomi 12S series. .
In addition, Xiaomi also announced that the new phone will use new battery materials, namely the new generation lithium cobalt oxide battery , and adopt battery negative electrode shunt technology, which will reduce the maximum temperature of the battery by 5°C during charging. The battery capacity of Xiaomi Mi 12S has also been increased by 100mAh to 4500mAh.
According to previous revelations, this model only weighs 183g, which is what Lei Jun said "a small body with a large battery".
In addition to Xiaomi 12S, the ultra-large Xiaomi 12S Ultra will use a more advanced and more expensive second-generation silicon-oxygen anode battery. The battery energy density is as high as 714Wh/L, which is 4 times the lithium ion storage capacity of traditional graphite . Although Xiaomi has not announced the battery capacity, it should be no less than a 4800mAh battery and support 67W wired fast charging and 50W wireless flash charging.
Xiaomi 12SUltra, the second-generation silicon-oxygen anode battery
Xiaomi 12SUltra, adopts the silicon-oxygen anode battery commonly used in new energy vehicles. Through the method of "replenishing lithium with silicon", nano-scale lithium-rich silicon-oxygen material is added to the battery negative electrode. Overcome the problem of low initial charging efficiency of silicon-carbon batteries and the easy pulverization of silicon particles, and solve the industry problem of short cycle life of silicon anode batteries. The second-generation silicon-oxygen anode material brings 4 times the lithium ion storage capacity and battery energy of traditional graphite. The density is as high as 714Wh/L, which is significantly higher than the previous generation
Xiaomi 12S. The new generation of lithium carbonate battery
Xiaomi 12S adopts a new generation of lithium carbonate battery material, which greatly improves the voltage resistance characteristics of the system and increases the battery energy density. Compared with conventional lithium oxide batteries, the battery cell width can be reduced by 1mm, and the internal battery protection plate is innovatively narrowed by 2.2mm. The battery power can be increased by up to 100mAh in the same volume, allowing 4500mAh to be accommodated in a small-sized body. Possibly. At the same time, Xiaomi 12S’s new generation lithium acid battery adopts battery negative shunt technology for the first time, which reduces the maximum battery temperature by 5°C during charging.
IT Home learned that Xiaomi also officially announced the new Pengpai G1 battery management chip today. , Xiaomi 12S Ultra will be equipped with two self-developed chips, Xiaomi Pascal P1 and Xiaomi Pascal G1, which can realize millisecond-level real-time monitoring of battery safety, greatly improve the accuracy of battery life prediction, and effectively increase the battery life of mobile phones.
