Reusable and fireproof ‘water batteries’ promise explosion-free power

A team of researchers led by the RMIT University in Australia has unveiled ‘water batteries,’ which promise to offer a safer alternative to lithium-ion energy storage. 
The team eliminates the risk of fires or explosions in their batteries by employing water instead of organic electrolytes. In contrast to lithium-ion counterparts, using water ensures enhanced safety by preventing such hazardous incidents while still facilitating the flow of electric current between the positive and negative terminals.
