Allegro Energy, a “global leader in long-duration energy storage”, says this milestone follows previous patent successes in Europe and several other key markets, “showcasing the international significance of Allegro’s breakthrough approach”.

Allegro notes that its 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 - and by overcoming key limitations of traditional aqueous and non-aqueous electrolytes, the technology significantly expands the electrochemical stability window, enhancing energy density while maintaining the affordability and safety of water-based systems.

“The U.S. patent reinforces Allegro’s ability to deliver a truly global and transformative solution for long-duration energy storage,” said Dr. Thomas Nann, CEO and Co-Founder Allegro Energy. “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,” notes Allegro.

“With this latest U.S. 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,” concludes Allegro.

About Allegro Energy
Allegro Energy has developed a water-based electrolyte that matches or outperforms the current state of the art in all forms of electrical energy storage from batteries to supercapacitors. This water-based electrolyte enables energy storage that is not only non-flammable but much less expensive and much safer than competing technology, opening up the ability to address needs at global scale. We’re also not reliant on scarce raw materials that are difficult to source or supply chains that are subject to geo-political power-games.
