The development of battery technology is very important for mobile phone users. The aim is not only to increase capacity, but also durability and charge time/cycle. A Xiaomi not the first to work on new battery technology, the graphene and MTW technology introduced in Mix 4 is nothing new. But now it's trying again!
(Sorry for the rough translation, I tried to make it clearer)
A new breakthrough in Xiaomi in battery technology! This is the first time battery-grade, high-silicon technology has been used in mobile phones. The silicon content has increased 3-fold. Combined with a completely upgraded packaging technology, the battery capacity increases by 10% with the same performance. In addition, the battery is equipped with Xiaomi's ripple charge level measurement chip. Research algorithms and lower-level data analysis, comprehensive security protection from hardware, software to cloud, realize the black technology of small size, large capacity and security protection, and comprehensively improve user experience.
A new generation of battery technology takes silicon to a new level. The single cell capacity increases to 67W with high power output of 8%. Combined with highly integrated packaging technology, battery capacity increases by 10% and battery life increases by 100 minutes. It will be released next year, with mass production starting in six months.
Xiaomi's new battery, battery-grade, adopts high-silicon technology, higher silicon content and introduces gradient-pole technology. It successfully adds a higher proportion of silicon to the negative electrode, which is the silicon-oxygen anode battery of conventional mobile phones. The content is increased 3-fold to obtain a higher energy density, which can bring the energy density of a fast-charging battery up to 740 Wh/L and also solves the problems of low first efficiency. High expansion and cycle damping, which gradually increase as the silicon ratio increases.
Pole piece compensation technology is used for the first time on mobile phone batteries. With this technology, an ultra-thin keng film is mixed on the surface of the negative terminal chip. Through an electrochemical reaction, the Keng metal can directly replenish the Keng lost during the activation process, thus compensating for the initial loss of battery capacity. However, the high risk of Keng metal is no longer present in compensating the capacity in this process. Therefore, bar piece patching technology provides a safe and reliable long-lasting experience.
In addition, gradient rod piece technology breaks through the technical limitations of traditional single-layer rod pieces and uses a composite design consisting of different materials from the inner layer to the outer layer. High-energy silicon materials are distributed in the inner layer and filler graphite materials are distributed in the outer surface layer to achieve. The hierarchical design of the pole gradient solves the problem of compatibility between high energy density and fast charging performance.
The highly integrated packaging is mainly composed of MCP and MNP technology, which makes the battery pack more compact and effectively improves the use of internal space.
MCP is Xiaomi's first mobile phone battery packaging technology. It uses the top seal of the cell for precise positioning and tightly controls the bending angle to achieve Z-type secure stacking of the top seal of the cell. At the same time, the PCM's outdated 90º position close to the battery cell can greatly reduce the battery height, make full use of the battery compartment, and improve the strength and safety of the overall protective plate and battery cell head.
Xiaomi's rising charge level measurement chip, the core of the smart battery system. Information data on battery material, user battery big data and battery encryption system support the evolution of the algorithm. Based on this data analysis to achieve full battery safety and extend battery life to improve user experience. At the same time, it breaks the industry's battery chip technology and exclusively develops new ISP and SOA functions, so that cells, batteries and systems can be combined more efficiently and further make batteries safer and healthier.
With local monitoring function, Mi Pao's charge level measurement chip intelligently detects the user's charging behavior at night, opens the night battery maintenance, avoids full charge status for a long time. Thus delaying battery aging and extending battery life. At the same time, combined with Xiaomi's industry-first battery time range intelligent technology, it can provide users with battery maintenance after high temperature season detection. It can reduce the high temperature aging factor of the battery and extend the battery life. Through Xiaomi's first low-power rolling battery life battery monitoring and calculation of daily and weekly battery usage patterns, it manages battery aging scenarios and maintains the battery. Connect to battery charger, terminal and cloud, intelligently identify batteries, smart charging options and smart reminders for for unofficial batteriesto avoid informal damage.
Slim, light, long battery life, smart core, this is a comprehensive update of Xiaomi's next generation battery technology.
