@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.

Climate-driven water stress could undercut most proposed U.S. lithium mines

The U.S. may not have enough water to support its lithium ambitions, a new Northwestern University study has found. An essential ingredient for electric vehicle (EV) batteries and other clean energy technologies, lithium is largely mined in Australia and Chile and then processed and refined in China. In recent years, however, the U.S. has pushed to develop its own lithium industry to reduce reliance on foreign supply chains.

Every scientific advancement to procure lithium easily, which is literally everywhere, is a step towards making sure that billionaire who wants to destroy a deep sea ecosystem because he is a selfish profit-centric prick goes out of business.

Researchers develop a new process to get lithium out of rocks

If it scales up, it can help us diversify our sources of a key element.

This is BAD trend for the long term viability of U.S.A.'s ability to compete in the battery and energy storage markets and technologies.

China is accelerating its dominance over critical mineral supply chains - notably
lithium. Chinese companies are on track to control 39% of global lithium production by 2030. https://www.mining.com/chinas-grip-on-lithium-to-hit-39-by-2030-woodmac/ #China #USA #Lithium #EVs #Batteries #Energy #LithiumProduction #ElectricVehicles #BatteryManufacturing

Researchers found a cleaner way to extract lithium for batteries, skipping the big evaporation ponds. #lithium

https://www.sciencedaily.com/releases/2026/05/260522023132.htm

Scientists just found a faster, cleaner way to extract lithium for EV batteries

A breakthrough lithium-extraction method could help solve one of clean energy’s dirtiest problems. Researchers at Columbia Engineering have developed a fast new technique that pulls lithium directly from salty underground brines using a temperature-sensitive solvent, avoiding the giant evaporation ponds that can take years and drain precious water supplies. Even better, the method works on low-quality lithium sources that current technologies struggle to use.
