Solar-Powered Desalination Produces Drinking Water and Recovers Valuable Minerals

Researchers at the University of Rochester, led by Professor Chunlei Guo, have developed an innovative solar-powered desalination system that converts seawater into drinking water while recovering nearly all salts in solid form. Unlike traditional desalination methods that create environmentally harmful brine, this system uses black metal panels etched with femtosecond lasers. The laser-textured surfaces make the panels highly absorbent of sunlight and extremely effective at wicking water. Water is pulled across the panel, evaporates, and leaves the salts to slide into untreated regions, preventing clogging and maintaining continuous operation. This technology not only produces fresh water but also isolates valuable minerals, including lithium, which is essential for lithium-ion batteries. In tests using water from three oceans and the Great Salt Lake, the system extracted almost all salts and recovered about 50% of lithium from the residual minerals. The panels’ design allows for scalable applications, offering potential global benefits for drinking water access and sustainable mineral sourcing. Funding came from the National Science Foundation, the Bill & Melinda Gates Foundation, and the Worldwide Universities Network. While the technology is still in the proof-of-concept stage, its innovative approach could reduce energy consumption and environmental impact compared to conventional desalination.

@paulschoe please buy 1x #sodium cell and drive a nail through it

Is #sodium safer than #lithium ? It seems like "it depends"
https://techxplore.com/news/2026-04-safer-sodium-battery-thermal-runaway.html
It seems sodium-ion can also thermal run away when puctured for example

what safety risks are associated with sodium-ion batteries?

Thermal runaway / fire: still possible (especially with flammable organic electrolytes and high states of charge), though many studies find SIBs generally show lower heat release and slower propagation than Li‑ion cells.

Electrolyte flammability and decomposition gases: conventional non‑aqueous electrolytes can ignite or produce toxic/reductive gases during abuse or overheating; nonflammable electrolytes are an active research area.

SEI instability and parasitic reactions: sodium salts and solvents can form less stable solid–electrolyte interphases than lithium systems, causing continuous side reactions... #goodbms is key (again) #need #team #electricalengineer build better #bms

Safer sodium battery eliminates thermal runaway with a heat-triggered polymer barrier

Some batteries have been known to catch fire or explode at high temperatures or when under stress. This safety concern has pushed researchers to experiment with different ways to design safer batteries that can ideally still perform reliably and efficiently. Sodium-ion batteries (NIBs) are considered a promising alternative to lithium-ion batteries, but still face safety risks, especially at high capacities. But now, a team of researchers in China has designed a new type of electrolyte for NIBs that may eliminate these risks, allowing for stable performance across a wide temperature range.

Forschende der #UniversityofRochester haben ein solares Verfahren entwickelt, das #Meerwasser entsalzt und zugleich #Lithium für #EAuto-Akkus gewinnt.

Laserstrukturierte Metallpaneele verdunsten Wasser effizient, während Salze in fester Form zurückbleiben. So entstehen #Trinkwasser und verwertbare Rohstoffe ohne belastende Sole.

In Tests konnte rund die Hälfte des enthaltenen Lithiums isoliert werden. Die Technologie ist skalierbar, aber noch im Laborstadium.

Rohstoff für E-Auto-Akkus: Neue Methode gewinnt Trinkwasser und Lithium aus Meerwasser

Die Gewinnung von sauberem Wasser und wichtigen Rohstoffen für die Energiewende sind zwei große Herausforderungen. Ein neues Verfahren auf Basis von Verdunstung soll beide gleichzeitig bewältigen. Die zurückbleibenden Salze werden dabei nicht zum Problem, sondern zur Ressource.

#MIT researchers develop a low-cost technique to get #lithium out of rocks
The low-temperature process could unlock cleaner lithium from America’s abundant hard rock while minimizing waste.
Currently, lithium hard rock extraction involves baking the rock at over 1,000C and chemically leaching it to extract lithium. Now, a team has developed a low-temperature process for extracting battery-grade lithium from the most common type of lithium-bearing mineral.

MIT researchers develop a low-cost technique to get lithium out of rocks

MIT researchers developed a low-temperature process for extracting battery-grade lithium from the common mineral spodumene. The closed-loop process could help the U.S. tap into its own abundant sources of lithium, a critical element that is currently refined primarily in China.
