Hydro-Québec to commercialize patents co-invented by Goodenough and Braga for electrolyte for solid-state Li-ion batteries

Hydro-Québec and The University of Texas at Austin signed an agreement for the transfer to Hydro-Québec of patents co-invented by Dr. John B. Goodenough, a professor at The University of Texas at Austin and the 2019 Nobel Laureate in chemistry and Dr. Maria Helena Braga, an associate professor at the University of Porto, Portugal.

These patents relate to a new type of electrolyte to be used in solid-state lithium batteries, which Hydro-Québec’s team of researchers will integrate into a battery with the goal of bringing it to the commercialization stage.

The relationship between The University of Texas at Austin and Hydro-Québec has been long-standing and fruitful; he two institutions have been collaborating for 25 years.

Previous agreements have allowed Hydro-Québec to bring previous University of Texas at Austin patents to the licensing stage and helped bring to market battery innovations that are now used all over the world in a wide range of electronic products.

The partnership with Hydro-Québec has provided the critical technology development needed for commercial production of intellectual property generated at The University of Texas at Austin.

—Dr. Goodenough

Lithium-ion batteries, an invention largely credited to the work of Dr. Goodenough, are the most common type of battery used in electronics and electric vehicles today. Solid-state batteries are considered a safer alternative to present-day lithium-ion batteries, as they do not use flammable liquid electrolytes. In addition, they have a high energy density and are long-lasting, light and much cheaper, making them ideal for the electric transportation market. This technology may be the key to both a greater driving range and greater safety, helping to secure the future of electric vehicle batteries.

Hydro-Québec developed a first-generation solid-state battery in the 1990s and has continued research and development work on improving both efficiency and manufacturing methods with a view to production of a new generation of batteries.



They have also had lousy power output, as it is tougher to move lithium around in a solid than a liquid.

Whether they have cracked that without messing up other metrics is what will count.
