This year could finally be marked by faster and more efficient development of mobile batteries. The silicon-carbon batteries presented by Honor at the recent MWC fair in Barcelona looked like a cry into the dark, but Xiaomi soon responded. This revealed the details on Weibo Solid-state batterieswhich the brand has already successfully tested on the Xiaomi 13 prototype. Compared to currently used batteries with liquid electrolyte, a solid electrolyte is used.
The new battery technology is supposed to make available an energy density of up to 1,000 Wh/l, which is significantly more than that of current Li-Ion batteries (typically 500 – 600 Wh/l). If we show it on a specific example, the Xiaomi 13, which normally has a 4,500mAh battery, had a Solid-state battery with a capacity of 6,000mAh. And that means an increase in capacity by a third! Of course, while maintaining the existing dimensions of the firmly integrated battery.
Solid state batteries will also have advantages in smartphones with regard to safety. When the batteries are punctured, they do not explode or catch fire
In addition, Xiaomi adds that Solid-state batteries are safer than currently used Li-Ion batteries. There is no risk of a short circuit or fire when they are punctured, and the new type of batteries also provide up to 20% more energy in extreme conditions (-20°C). However, while Honor has already used its Silicon-Carbon batteries in the Chinese version of the Magic5 Pro, Xiaomi is not yet ready for mass production of Solid-state batteries. It will probably take a few years for the new battery technology to catch up.
