The company is working on developing solid-state batteries
that can be used for mobile devices and, most importantly, EVs.
The Chinese tech giant said it had made a big breakthrough
and achieved a massive 1,000 Wh/l energy density. That's more than twice the
energy density most EVs have to offer. As of now, that's about 450 Wh/l.
The new tech promises to solve many issues with modern
lithium batteries. Aside from the improved energy density, solid-state
batteries also perform better in low temperatures. Xiaomi claims about 20%
improved efficiency at -20°C.
In addition, solid-state cells are safer as they don't
explode when punctured due to the lack of liquid electrolytes.
The engineers further improved durability by coating the
positive electrode with solid electrolyte ceramics.
Xiaomi tested its prototype on a Xiaomi 13 smartphone and
was able to cram up a 6,000 mAh unit inside the small handset.
As is usually the case with cutting-edge tech, the real
challenge is producing those batteries at scale and making them economically
viable. Xiaomi still has a long way to go, but if it keeps the current pace, we
may very well see a Xiaomi-made EV powered by a solid-state battery in the
coming years.
