Allegro Energy has been granted a US patent for its cutting-edge micro-emulsion electrolyte technology, further solidifying its position as a global leader in long-duration energy storage. This milestone follows previous patent successes in Europe and several other key markets, showcasing the international significance of Allegro’s breakthrough approach.
Allegro’s modular micro-emulsion electrolyte system is a game-changer for the energy storage industry, enabling safer, more cost-effective, and scalable solutions for applications ranging from grid storage to renewable energy integration.
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.
“The US patent reinforces Allegro’s ability to deliver a truly global and transformative solution for long-duration energy storage,” said Allegro Energy CEO Thomas Nann. “With energy storage playing a crucial role in the renewable transition, our micro-emulsion platform ensures scalability and adaptability across a range of battery chemistries, from redox flow to advanced ion batteries.”
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.
With this latest US patent covering all of Allegro’s intended claims, Allegro Energy is well-positioned to partner with utilities, industrial operators, and battery manufacturers worldwide to drive the future of clean energy storage and rapidly support the drive to 24/7 carbon-free energy.
