Argonne innovations and technology to help drive circular economy | US Department of Energy Science News


DOE/Argonne National Laboratory
Argonne is looking at alternative supply chains for critical materials, says Cynthia Jenks, head of Argonne s circular economy initiative. Mining these materials from our nation s urban sources would enhance national security.

Imagine 10 million people, each drinking a bottle of water a day and then deciding on what to do with the container. Do they throw it in the trash, toss it to the gutter or recycle it?
This isn t a far-fetched scenario. In fact, U.S. consumers purchased nearly 50 billion water bottles in 2018, or about 137 million bottles a day, according to one estimate. ....

Breakthrough greatly enhances the ultrafast resolution achievable with X-ray free-electron lasers.
A large international team of scientists from various research organizations, including the U.S. Department of Energy s (DOE) Argonne National Laboratory, has developed a method that dramatically improves the already ultrafast time resolution achievable with X-ray free-electron lasers (XFELs). It could lead to breakthroughs on how to design new materials and more efficient chemical processes. ....

New Lead-based Anode for Next-generation Lithium-ion Batteries


New Lead-based Anode for Next-generation Lithium-ion Batteries
The lithium-ion battery powers everything from mobile phones to laptops to electric vehicles. Scientists worldwide are always on the hunt for new and improved components to build better batteries for these and other applications.
Scientists from the U.S. Department of Energy’s (DOE) Argonne National Laboratory report a new electrode design for the lithium-ion battery using the low-cost materials lead as well as carbon. Contributors to this pivotal discovery also include scientists from Northwestern University, Brookhaven National Laboratory and the Ulsan National Institute of Science and Technology (UNIST). 
“Our research has exciting implications for designing low-cost, high-performance, sustainable lithium-ion batteries that can power hybrid and all-electric vehicles,” said Eungje Lee, principal author and materials scientist in Ar ....
