China’s smartphone brand Xiaomi has shown a solid-state battery technology that provides higher mechanical strength and stability as well as higher capacity in its latest flagship smartphone Xiaomi 13 series, reported eeNews on March 10.

In laboratory tests, the solid-state battery technology achieved an energy density of over 1000Wh/L, a 20% improvement in low-temperature discharge performance and a significant increase in the pass rate of pinprick experiments.

The energy density of 1000Wh/l tops the 800Wh/l of silicon-based lithium ion packs with a liquid electrolyte. Ilika in the UK and Solithor in Belgium and iten in France are all working on solid state battery systems, and Sakuu in the US has demonstrated 3D printed lithium metal solid state cells.

On a modified Xiaomi 13, the bating to eeNews. tery achieved a capacity of 6,000mAh with higher reliability. The comapny’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, according to the company.

Xiaomi also debuted its 300 W HyperCharge technology at the beginning of March. 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.

The solid state battery uses a lithium metal anode with an inorganic diaphragm to prevent the growth of lithium dendrites that can penetrate the layers of the cell and cause short circuits and fires.

Another major benefit of solid-state batteries is the improved performance at low temperatures. The labs tests shows the solid-state battery has a 20% improvement in performance compared to regular batteries at -20°C, providing reliable operation in cold climates and conditions, said eeNews.
