Researchers create flexible battery that can run on salt water
Instead of packing electrolytes that are corrosive or toxic, the team used sodium-based chemicals like sodium sulfate, which was once used as a laxative, as well as saline and a solution used for cell culture. While it’s still preferable that those solutions don’t leak out of the batteries and onto or inside of a human, if they do, it wouldn’t pose the same risks that other batteries’ chemicals…
