Boulder Ionics signs exclusive licensing agreement with CSIRO for pyrrolidinium-based ionic liquids in battery electrolytes

Boulder Ionics Corp., developer and producer of high-performance electrolytes and electrochemical-grade ionic liquids for advanced energy storage devices (earlier post), signed an exclusive worldwide licensing agreement with Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia’s national science agency, to develop and commercialize the use of pyrrolidinium-based ionic liquids in electrolytes for lithium-ion and advanced chemistry batteries.

Under the terms of the agreement, the Boulder Ionics research team will work with CSIRO to develop electrolyte formulations optimized for specific applications. Pyrrolidinium-based ionic liquids have been identified by researchers worldwide as promising next-generation electrolytes for lithium-ion batteries.

The high stability of these electrolytes enables batteries that can work at very high temperatures, high voltages and with next-generation “beyond lithium-ion” technologies like lithium-sulfur and metal-air batteries. Boulder Ionics will use its high-throughput synthesis platform to produce high purity electrolytes in commercial volumes at competitive prices.

CSIRO has been actively researching and developing ionic liquids for electrochemical applications, especially lithium batteries, for 10 years now. By licensing our technology portfolio and developing a strong collaboration with Boulder Ionics, we believe substantial improvements to lithium battery technology are just around the corner.

—CSIRO Research Scientist Dr. Adam Best

Boulder Ionics’ Iolyte ionic liquids and electrolytes displace conventional carbonate-based solvents and lithium salts and offer increased safety and broader operating temperatures in applications including ultracapacitors, lithium-ion batteries and next-generation metal-air batteries.



One more building block towards improved lower cost ultra caps and batteries. Coupled with improved advanced Anodes and Cathodes, 3-3-3 reliable batteries become a strong possibility for the not too distant future.
