Bill Strunk of Oak Ridge National Laboratory’s Nuclear Science and Engineering Directorate has received the ORNL Director’s Award for Outstanding Individual Accomplishment in Science and Technology.

ORNL Director Thom Mason presented the top researcher award to Strunk during Friday night’s annual Awards Night event hosted by UT-Battelle, the management and operating contractor of ORNL for the U.S. Department of Energy.

Strunk was recognized for exemplary leadership of ORNL’s uranium science and engineering programs, which has led to enhancements in the nation’s nuclear security, a press release said. He is also credited with the establishment of research and development capabilities and facilities that will enable ORNL to excel in vitally important areas of research. Strunk, who works in the Enrichment Science and Engineering Division, also earned the Division Level Research Leadership award.

Recycled tires could see new life in lithium-ion batteries that provide power to plug-in electric vehicles and store energy produced by wind and solar, say researchers at Oak Ridge National Laboratory.

By modifying the microstructural characteristics of carbon black, a substance recovered from discarded tires, a team led by Parans Paranthaman and Amit Naskar is developing a better anode for lithium-ion batteries. An anode is a negatively charged electrode used as a host for storing lithium during charging.

The method, outlined in a paper published in the journal RSC Advances, has numerous advantages over conventional approaches to making anodes for lithium-ion batteries.

“Using waste tires for products such as energy storage is very attractive not only from the carbon materials recovery perspective but also for controlling environmental hazards caused by waste tire stock piles,” Paranthaman said.

The ORNL technique uses a proprietary pretreatment to recover pyrolytic carbon black material, which is similar to graphite but man-made. When used in anodes of lithium-ion batteries, researchers produced a small, laboratory-scale battery with a reversible capacity that is higher than what is possible with commercial graphite materials.
