Researchers have developed a prototype lithium-ion battery that uses water as an electrolytic solution. The water replaces a flammable organic solvent.

The good news, according to the team of scientists, is that their prototype is durable, can be quickly recharged, and is free from the risk of catching fire. (Just a reminder that gasoline in ICE cars is flammable, folks.)

In the abstract published in the Proceedings of the National Academy of Sciences of the United States of America, the abstract states that the prototype achieves “higher ionic conductivity, environmental benignancy, and high safety.”
