A freeze-thaw molten salt battery for seasonal storage

Posted by in categories: innovation, robotics/AI

It relies on a new “freeze-thaw” design. A recent study has just been published by U.S. scientists who have managed to develop an aluminum-nickel molten salt battery that can retain over 90% of its initial capacity over a period of up to 12 weeks. Having an energy density of 260 W/hour per kg, the new battery was built with an aluminum anode and a nickel cathode, immersed in a molten-salt electrolyte.


The breakthrough could have many applications in soft robotics including in the Metaverse.
