Interestingly, the researchers say that these new batteries will be twice as energy-dense as traditional lithium-ion options. This holds the potential to revolutionize the electric vehicle industry.

Moreover, aqueous batteries use water as the solvent for electrolytes, enhancing their safety. Traditional non-aqueous lithium-ion batteries have a high energy density, but their safety is compromised due to the flammable organic electrolytes, a component that allows the battery to charge and discharge, they utilize.

Lower energy density

However, aqueous batteries generally have a lower energy density due to the limited solubility of the electrolyte and low battery voltage.
