Argonne National Laboratory has been involved in research and development of the battery for more than 40 years. More than 10 years ago, the research center made the strategic decision to expand its investigation of lithium-ion batteries, with emphasis on application development for electric cars.

That decision, and subsequent investments for research by the U.S. Department of Energy, have produced technology transfer agreements, 149 inventions, more than 40 patents and four R & D 100 Awards.

In a natural progression, Argonne is now continuing research in lithium-air. Li-air using an air cathode catalyst that converts oxygen to peroxide, lithium, an electrolyte and an anode of Li.

Li-air batteries hold the promise of increasing energy density up to five to 10 times compared to lithium ion batteries. But that potential can not be made until the critical scientific challenges to be addressed. View Jeff Chamberlain Argonne discuss this technology.

Argonne personnel world-class interdisciplinary researchers has developed a broad and deep understanding of the scientific challenges involved in developing advanced batteries. Researchers will continue building on this knowledge to jump the high hurdles required for the development of commercially viable Li-air batteries. View Argonne materials scientist Khalil Amine discuss this research.

Ensuring safe operation of the battery is one of the main challenges is the development of materials to ensure the reliability and safety. While the potential of Li-air batteries is large, the investigation will take time to reach and close working relationships with industry that finally adopt the technology for commercial applications. See Michael Thackeray, Argonne distinguished member, discuss this adaptation.
