A US research team raised the capacity and voltage of a lithium-sulfur battery using a three-electron sulfur reaction. We compare the electrode-level figures, the calculated cell-level value, and the pouch-cell durability test to see what practical use still requires.
US rare earth mine production rose to 51,000 tons in 2025, but USGS data show net import dependency for compounds and metals jumped from 53% to 67%. The bottleneck lies in separation and refining capacity, not mining—a structural gap that could keep China dependence intact into the 2030s.
South 8 has begun running a semi-automated line for extreme-cold lithium-ion cells. The 5 MWh per year figure is a 2027 capacity target, a different stage from customer prototype work or compliance with U.S. sourcing rules.
Google will launch the first satellite for its Project Suncatcher space-based AI data center initiative aboard SpaceX next week, testing in orbit whether TPUs can withstand radiation, radiate heat in a vacuum, and support ultra-close formation flying.
Qnetic's Pulsar flywheel, designed for 200kWh storage, has begun integrated low-speed testing. A 100-cycle trial and separate motor tests show early progress, but a temporary steel rotor and independent evaluation leave key questions unanswered.
Modal Motors is taking orders for drone motors, but first deliveries are still planned. We look at its rare-earth-free and U.S.-sourced versions, when Niron's magnets will reach mass production, and what performance data has been disclosed.
At least 45 US data center projects, valued at about $68 billion, were blocked or delayed by local opposition in April–June 2026. Here is what the figure does and does not mean, and how New York's voluntary guidance frames who bears local costs.
Soochow University and LONGi placed insulating zirconia particles at a buried interface to cut charge losses in a tandem solar cell. Here is how it works, what the certified figure means, and what the 2,000-hour test shows.
SwRI has introduced the Electrical Interchangeability Index (EII) to compare sodium-ion and lithium-ion batteries by application. Peer-reviewed research shows how temperature, charge level and load matter, while the limits of the published data remain.
A research team including Yunnan University ran a solar cell underwater for two hours at a depth of 10 meters, storing 324 mWh. Here's what the 34.71% efficiency figure and roughly 5.49-year lifespan estimate actually measure.
