The race for the “holy grail” of EV batteries is heating up. Mercedes-Benz is now testing EVs with solid-state batteries on the street, which may unlock over 600 miles of driving vary.
Mercedes solid-state battery-powered EVs hit the street
Mercedes is working with US-based Factorial Power to launch the brand new battery tech, promising extra driving vary, sooner charging, and effectivity.
Final summer season, Factorial delivered its first solid-state battery cells primarily based on its propriety FEST (Factorial Electrolyte System Know-how).
Mercedes and Factorial took it a step additional, revealing the extra superior all-solid-state Solstice battery in September. The brand new batteries are being co-developed to energy Mercedes’ next-gen electrical fashions. With a sulfide-based stable electrolyte, the battery is safer and extra environment friendly.
With a “breakthrough” vitality density of 450 Wh/kg, Factorial mentioned the brand new Solstice battery is predicted to offer 80% extra driving vary than present lithium-ion batteries.
In accordance with Autocar, Mercedes is already testing EVs with solid-state battery tech on the street. The assessments are going down within the UK utilizing an EQS prototype outfitted with the brand new batteries.

Though full specs have but to be confirmed, Mercedes mentioned the EQS’s 12-module battery housing was versatile sufficient for various configurations.
Mercedes expects the brand new battery to increase the driving vary by about 25%. The present EQS 450+ rated with as much as 511 WLTP miles vary would recommend a driving vary of over 620 miles.

Factorial goals to unlock over 600 miles of driving vary with 40% weight financial savings in comparison with standard Li-ion batteries. The corporate says Solstice is 33% smaller than a present 90 kWh battery at 580 lbs.
In December, Factorial introduced a serious milestone after its Solstice all-solid-state battery cells achieved 40 Ah capability. The corporate is working with different main automakers, together with Hyundai and Stellantis, to advance solid-state battery expertise and goals to launch solid-state batteries by 2030.

In accordance with Mercedes chief tech officer Markus Shafer, the brand new Solstice batteries will “set new requirements in vary, value, and efficiency. ” Mercedes expects to be producing solid-state batteries at scale by the top of the last decade.
Electrek’s Take
Mercedes is amongst a number of automakers and different corporations creating solid-state batteries in hopes of unlocking extra vary, security, and effectivity.
The information comes after native studies earlier this month steered Hyundai will reveal its all-solid-state EV battery demo line in March. Japanese rival Honda unveiled its pilot line to the general public in November.
Stellantis introduced plans to launch a fleet of electrical Dodge Chargers powered by Factorials solid-state batteries in 2026.
Hyundai, Honda, Toyota, Stellantis, and others goal to mass-produce solid-state batteries by the top of the last decade.
And don’t overlook that Chinese language EV battery leaders BYD and CATL are additionally racing to launch solid-state batteries. Which firm will come out on high?
