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 ....

UNIST team develops new electrolyte additive for high-energy-density Li-ion batteries

UNIST team develops new electrolyte additive for high-energy-density Li-ion batteries
Researchers at the Ulsan National Institute of Science and Technology (UNIST) in Korea have developed an innovative electrolyte additive that enables a high-energy-density Li-ion battery to retain more than 80% of its initial capacity even after hundreds of cycles.
When this additive was added to a large-capacity battery composed of a high-nickel anode and a silicon mixed anode, the initial capacity was maintained at 81.5% even after 400 charging and discharging cycles 10% to 30% better than commercial additives such as FEC (fluoroethylene carbonate) or VC (vinylene carbonate).
An open-access paper on their work is published in ....

Despite worldwide use of lithium batteries, the exact dynamics of their operation has remained elusive. X-rays have proven to be a powerful tool for peering inside of these batteries to see the changes that occur in real time.
Using the ultrabright X-rays of the Advanced Photon Source (APS), a U.S. Department of Energy (DOE) Office of Science User Facility at the DOE s Argonne National Laboratory, a research team recently observed the internal evolution of the materials inside solid-state lithium batteries as they were charged and discharged. This detailed 3D information may help improve the reliability and performance of the batteries, which use solid materials to replace the flammable liq ....

Using X-ray tomography, a research team has observed the internal evolution of the materials inside solid-state lithium batteries as they were charged and discharged. Detailed three-dimensional information from the research could help improve the reliability and performance of the batteries, which use solid materials to replace the flammable liquid electrolytes in existing lithium-ion batteries.
The operando synchrotron X-ray computed microtomography imaging revealed how the dynamic changes of electrode materials at lithium/solid-electrolyte interfaces determine the behavior of solid-state batteries. The researchers found that battery operation caused voids to form at the interface, which c ....
