The Chinese electronics behemoth Xiaomi has revealed a breakthrough in solid-state batteries technology that should result in increased energy density, improved low-temperature performance, and improved safety.
The business is aiming to create solid-state batteries that can be utilized by EVs and, more crucially, mobile devices.
Xiaomi’s Solid State Batteries Energy Density
The huge 1,000 Wh/l energy density was said to be a major advance by the Chinese tech company. That is more than twice what most EVs can deliver in terms of energy density. It currently amounts to roughly 450 Wh/l.
The new technology promises to address a number of problems with contemporary lithium batteries. Solid-state batteries not only have a higher energy density but also work better in colder temperatures. At -20°C, Xiaomi claims a 20% improvement in efficiency.
Also, solid-state cells are safer because they don’t blow up when pierced because they don’t contain liquid electrolytes.
The positive electrode was coated with solid electrolyte ceramics to increase durability even more.
Xiaomi managed to fit a 6,000 mAh battery inside the compact Xiaomi 13 smartphone during testing.
The true problem with cutting-edge technology, as is typically the case, is making such batteries commercially feasible and scalable.
While Xiaomi still has a ways to go, if it continues on its current path, we may very well see an electric vehicle (EV) produced by Xiaomi that is powered by a solid-state battery in the years to come.
