The battery achieves impressive energy densities of 330 Wh/kg and 842 Wh/L, with ongoing tests on a 20 Ah cell format aiming for even higher figures of 370 Wh/kg and 1,000 Wh/L.

Notably, these batteries can last up to 1,200 cycles, significantly outpacing traditional batteries that typically last between 500 to 1,000 cycles.

The new battery technology is designed to integrate seamlessly into existing lithium-ion battery manufacturing processes, making it compatible with various cell formats.

Sionic plans to produce enough silicon-carbon composites to equip approximately 200,000 electric cars annually, with Group14 Technologies set to open a manufacturing facility in 2025 to produce 4,000 tons of the composite each year.

This innovative battery technology could significantly accelerate the adoption of electric vehicles and contribute to the mass electrification of transportation.

Sionic Energy has unveiled a groundbreaking electric vehicle battery that can charge in just 10 minutes, utilizing a 100% silicon anode.

The silicon-carbon composite, known as SCC55, was developed in collaboration with Group14 Technologies to enhance overall battery performance.

This innovative battery technology boasts a significant increase in energy density, offering 50% more storage capacity compared to traditional graphite batteries.

Central to this advancement is the SCC55 composite, which enables controlled expansion during charging, ensuring stability and longevity over multiple charge cycles.

Beyond electric vehicles, the battery technology holds potential applications in electronics and aviation, including use in electric aerial vehicles like eVTOL flying taxis.
