Stellantis is about to test the first-ever production-line lithium-sulfur batteries
In a milestone, supermaterials trailblazer Lyten has shipped lithium-sulfur (Li-S) batteries to Stellantis and other US and EU OEMs for testing.
Lyten’s shipment of A samples of its 6.5 Ah Li-S pouch cells is the first major step in the commercial evaluation of lithium-sulfur batteries by leading US and European automakers. Stellantis announced that it had invested in Lyten’s lithium-sulfur battery development in May 2023.
“This milestone is the result of years of dedicated work and innovation from the Lyten team, and we are just at the start of further expanding the capabilities of our lithium-sulfur battery cells,” said Lyten CEO and cofounder Dan Cook.
Operating from its automated pilot production line in San Jose, California, which came online in May 2023, Lyten produces lithium-sulfur batteries using standard lithium-ion manufacturing equipment and practices. The company plans to ship cylindrical A samples later this year, and its first giga-scale factory is currently being designed.
Lithium-sulfur batteries face issues related to cycle life and stability under real-world operating conditions, but Lyten says it’s addressed those challenges in its lithium-sulfur EV batteries.
Lyten has integrated its proprietary 3D graphene structure within the Li-S battery’s cathode. This structure enhances the battery’s overall stability and conductivity, addressing common issues such as the polysulfide shuttle effect, which typically leads to rapid capacity loss in Li-S batteries.
By using a lithium metal composite for the anode instead of the traditional graphite, Lyten has improved the anode’s stability and efficiency. This modification also helps to increase the battery’s overall energy density while potentially reducing degradation over time.
The need for critical minerals like nickel, cobalt, and manganese in the cathode is also eliminated, and that means a projected 65% lower carbon footprint than lithium-ion batteries and a supply chain that can be fully sourced in the US or EU at scale.
In February 2024, Chrysler announced the inclusion of Lyten’s Li-S batteries in its Halcyon concept EV, and the US Department of Energy has granted Lyten $4 million to accelerate development. Lyten has raised more than $410 million in equity capital to date.

The US solar industry just delivered another huge quarter, installing 11.7 gigawatts (GW) of new capacity in Q3 2025. That makes it the third-largest quarter on record and pushes total solar additions this year past 30 GW – despite the Trump administration’s efforts to kneecap clean energy.
According to the new “US Solar Market Insight Q4 2025” report from Solar Energy Industries Association (SEIA) and Wood Mackenzie, 85% of all new power added to the grid during the first nine months of the Trump administration came from solar and storage. And here’s the twist: Most of that growth – 73% – happened in red states.
Eight of the top 10 states for new installations fall into that category, including Texas, Indiana, Florida, Arizona, Ohio, Utah, Kentucky, and Arkansas. Utah jumped into the top 10 this quarter thanks to two big utility-scale projects totaling more than 1 GW.
But the report also flags major uncertainty ahead. Federal actions, including a July memo from the Department of the Interior (DOI), have slowed or stalled the approvals pipeline for utility-scale solar and storage. Without clarity on permitting timelines, Wood Mackenzie’s long-term utility-scale forecast through 2030 remains basically unchanged from last quarter.
“This record-setting quarter for solar deployment shows that the market is continuing to turn to solar to meet rising demand,” said Abigail Ross Hopper, SEIA’s president and CEO. She added that strong growth in red states underscores how decisively the market is shifting toward clean energy. “But unless this administration reverses course, the future of clean, affordable, and reliable solar and storage will be frozen by uncertainty, and Americans will continue to see their energy bills go up.”
Two new solar module factories opened this year in Louisiana and South Carolina, adding a combined 4.7 GW of capacity. That brings the total new US module manufacturing capacity added in 2025 to 17.7 GW. With a new wafer facility coming online in Michigan in Q3, the US can now produce every major component of the solar module supply chain.
“We expect 250 GW of solar to be installed from 2025 to 2030,” said Michelle Davis, head of solar research at Wood Mackenzie and lead author of the report. “But the US solar industry has more potential. With rising power demand across the country, solar could do even more if current constraints were eased.”
SEIA also noted that, following an analysis of EIA data, it found that more than 73 GW of solar projects across the US are stuck in permitting limbo and at risk of politically motivated delays or cancellations.

The spiritual successor to the beloved Chevy Geo Tracker, production of the new-for-2026 electric Spark EUV has officially begun in Brazil with more than 200 miles of range.
That’s right, kids. To know the Chevy Tracker is to love the Chevy Tracker. The tiny, top-heavy Suzuki-based SUV combined bold colors, fun styling, (relatively) good fuel economy, and real off-road chops (especially in ZR2 trim) with an affordable price tag to make the Tracker an early favorite among the serious rock-crawling crowds.
Like, really
While it’s still too early to tell whether or not the all-new Chevy Spark EUV will come even close to that little proto-SUV, it seems we won’t have to wait much longer to find out – GM Authority reports that production of the 2026 Chevy Spark EUV has officially begun at Comexport’s Planta Automotiva do Ceará (PACE) plant, in the state of Ceará, Brazil.
GM Brazil invested the equivalent of $73 million to get the PACE factory ready to assemble GM’s modern, zero-emissions Chevy crossover for the South American and Middle Eastern markets – an investment big enough to earn a visit from Brazilian president Luiz Inácio Lula da Silva, who was on-hand for the December 3rd kickoff event.
“It’s not a car factory,” said Comexport Vice President and PACE shareholder, Rodrigo Teixeir. “(The) goal is to develop technology there, not simply assemble a vehicle.”
Production of the new Spark EUV began last week, with production of the equally new Chevy Captiva EV set to begin as early as Q1 of 2026.
2026 Chevy Spark EUV
The Made in Brazil Chevrolet Spark EUV is heavily based on the Chinese Baojun, and is powered by that vehicle’s single 75 kW (101 hp), 180 Nm (130 lb-ft) motor driving the front wheels. Power comes from the Baojun’s 42 kWh LFP battery that, with regenerative braking, is good for up to 360 km (220 miles) on the NEDC driving cycle.
Weirdly, the new Spark is also equipped with a 10.1″ infotainment screen and 8.8″ digital instrument cluster (above) that supports both Apple CarPlay and Android Auto standard – technology that GM claims lead to “unsafe” driver behaviors in North America.
Let us know what you think of the little electric SUV, and whether or not you think it would be a hit in the US (it would) in the comments.
