Mercedes unveiled its new all-solid-state EV batteries promising higher energy density and safety. Developed with Factorial, its new all-solid-state battery "breakthrough" can extend EV range by up to 80%.
Factorial is "at the cutting edge" of solid-state EV battery tech. The US-based company claims its tech will extend EV range, increase safety, and reduce costs compared to what''s on the market today.
Mercedes was among several automakers, including Hyundai and Stellantis, that invested in Factorial''s $200 million fundraise in 2022.
The company has been advancing its proprietary solid-state FEST (Factorial Electrolyte System Technology) platform for years. Its solid-state battery cells based on the FEST platform were delivered to Mercedes earlier this summer.
On Tuesday, Factorial introduced its latest breakthrough, Solstice. The new all-solid-state EV battery was developed with Mercedes to power its next-gen models.
Factorial said its sulfide-based system addresses concerns over flammable liquid electrolyte designs. It will also maintain stability when operating at temperatures over 194°F (90°C).
The safer design can reduce the need for heavy cooling systems within the battery pack, which can drive even lower prices.
With a "breakthrough energy density" of 450 Wh/kg, Factorial claims the new tech can extend EV range by up to 80%. It will also drastically reduce the weight of EVs for even higher efficiency.
Factorial aims to unlock over 600 miles of driving range for future electric models with 40% weight savings (compared to traditional Li-ion batteries). The company says its tech is also 33% smaller.
Solstice will complement Factorial''s FEST platform for safer and more efficient electric vehicles. The new all-solid-state EV batteries are expected to launch by the end of the decade.
According to chief tech officer Markus Shafer, the new tech is a "cornerstone of Mercedes-Benz''s strategy and commitment" to leading EV battery development. Shafer added that Solstice will help Mercedes "set new standards in range, cost, and performance."
The new tech comes a day after after Toyota announced its plans to develop and produce all-solid-state EV batteries have been certified in Japan.
Anyone else confused by the timeline/development of solid state batteries? I have no idea if they''re going into serious production next year or 25 years from now.
Toyota is among several leading Japanese companies, including Nissan and Panasonic, aiming to boost domestic production. Japan seeks to secure a stable domestic supply chain to reduce reliance on China and South Korea, which currently dominate the global battery market.
Automakers are betting on solid-state batteries for longer-range, more efficient electric vehicles. However, significant challenges, including poor performance in extreme weather, have proven to be more complex than expected.
Update 9/12/24: Mercedes plans to begin testing EVs with solid-state batteries on the road ''in a few months."

Researchers at the University of Waterloo have made a significant breakthrough in lithium-ion battery design, enabling electric vehicles to achieve an impressive charging capability.
This advancement allows EVs to go from zero battery power to an 80% charge in just 15 minutes, greatly enhancing the convenience and efficiency of electric vehicle usage.
Fifteen minutes is significantly faster than the current industry standard of nearly an hour, even at fast-charging stations.
Batteries utilizing this new design can endure more charges—up to 800 cycles, a capability not achievable with current EV batteries.
"We need to make EVs more affordable and accessible, not just for the wealthy," said Yverick Rangom, a Department of Chemical Engineering professor.
"If we can make batteries smaller, charge faster, and last longer, we reduce the overall cost of the vehicle. That makes EVs a viable option for more people, including those who don''t have home charging stations or who live in apartments. It would also increase the value of second-hand EVs, making electric transportation more accessible."
This innovative design aims to alleviate "range anxiety," a common concern among drivers regarding the ability to travel long distances without readily available charging stations.
By addressing this issue, the design enhances the overall driving experience and encourages the use of electric vehicles.
It will also address another major barrier in the market: the reliability of used EVs.
This technology aims to clarify battery health for second-hand buyers by significantly improving its longevity, allowing it to endure up to 800 charges.
