Prototype Xiaomi 13 unit offers 6,000 mAh battery with breakthrough solid-state battery technology

Xiaomi has unveiled its next-generation battery technology, hot on the heels of Honor and the Chinese version of the Magic5 Pro. Incidentally, only a few days have passed since Xiaomi debuted its 300 W HyperCharge technology, which did not quite reach its 300 W advertised wattage. Still, the technology managed to recharge a 4,100 mAh battery in a mere 5 minutes, which is considerably faster than most conventional smartphone charging standards.

Xiaomi has now showcased its solid-state battery technology, which it has discussed on its Weibo account. Supposedly, the company has achieved 1,000 Wh/L energy density with some of its prototype batteries, which is considerably denser than consumer-grade batteries for the time being. Practically speaking, Xiaomi's solid-state battery would allow the Xiaomi 13 to offer a 6,000 mAh capacity within the same package size as the 4,500 mAh capacity shipping in retail units.

In short, the prototype solid-state battery delivers a 33% capacity uplift from current lithium-ion batteries. Additionally, Xiaomi claims that its solid-state battery is safer than lithium-ion alternatives, with no risk of puncture-related short circuits and fires. Moreover, Xiaomi asserts that the technology provides up to 20% more power than lithium-ion batteries in extreme cold, such as -20 degrees celsius. Unfortunately, Xiaomi is not ready to mass-produce these batteries yet. Instead, it will likely be a few more years before companies like Xiaomi pivot to solid-state batteries across their portfolios.
