The key advantage of Allegro’s micro-emulsion technology is its ability to dissolve a wider range of electrochemically active species, while maintaining stability at high voltages— previously a major barrier to the adoption of aqueous electrolytes in advanced energy storage.
The solution is applicable to multiple battery formats, including lithium-ion, sodium-ion, magnesium-ion, and aluminum-ion batteries, as well as supercapacitors and redox flow batteries.
By overcoming key limitations of traditional aqueous and non-aqueous electrolytes, Allegro’s technology significantly expands the electrochemical stability window, enhancing energy density while maintaining the affordability and safety of water-based systems.
