Xiaomi announced solid-state battery technology in China. This tech will offer higher energy density amongst other things. Before we get to it, however, it’s worth noting that HONOR introduced the very first silicon-carbon battery a couple of days ago.
That battery was announced during the HONOR Magic5 Pro launch. It is already used in the phone, but only in the Chinese model. That tech offers a 12.8% improvement when it comes to energy density compared to lithium batteries.
Xiaomi announced solid-state battery tech which offers higher energy density & more
On the flip side, Xiaomi says that its pre-developed solid-state battery tech can achieve an energy density of over 1,000Wh/L. In other words, it can technically offer an improvement of 20%. It can also offer a 20% improvement in low-temperature discharge performance, and an increase in the acupuncture experiment passing rate.
So, what makes these solid-state batteries different? The answer is… the electrolyte. Solid electrolytes offer better mechanical strength than liquid ones. They’re also great in the low energy density state, low temperature performance, and are technically safer, it seems.
Earlier, we mentioned that these batteries have an energy density of over 1,000Wh/L. That is a considerable improvement over regular lithium batteries, and it allows for more energy to be stored in the same space.
Safety is another aspect that sets them apart
Xiaomi also mentioned safety as another aspect of why these batteries are superior. They are safer than regular ones, as solid electrolytes can prevent the penetration of lithium dendrites.
Needless to say, this is very interesting, and it could potentially push the battery tech forward. Those batteries are not yet ready for primetime, it seems, but Xiaomi did put one in the Xiaomi 13 prototype for testing purposes. It did great in terms of endurance.
Xiaomi did not say when can we expect these batteries in commercial products.
