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.

While lithium-ion dominates the market, the emergence of new aqueous zinc-ion battery technology signifies a significant shift towards safer and more sustainable energy storage solutions, according to researchers. 

The details of the team’s research were published in the journal Advanced Materials.
