Research Explores How Rechargeable Batteries Degrade
November 16, 2023 | Leave a Comment
Pacific Northwest National Laboratory researchers have upended what’s known about how rechargeable batteries function. Rechargeable battery performance could be improved by a new understanding of how they work at the molecular level. For decades, researchers have assumed that the inevitable filmy buildup on electrodes inside rechargeable batteries is the driver of performance loss. Research shows […]

Texas A&M University scientists use quantum methods to predict Lithium-metal (Li-metal) batteries great potential for packing more significant amounts of energy than the current lithium-ion batteries. For example, a Li-metal electric battery in a car could travel more miles, and a Li-metal phone battery could have longer battery life. However, the metal surface of Li-metal […]

Images Made Of the Gunk That Forms In Lithium Batteries
February 23, 2022 | Leave a Comment
SLAC National Accelerator Laboratory scientists have made realistic close-ups of a plump, squishy layer called the solid-electrolyte interphase (SEI) that forms on lithium metal anodes as a result of chemical reactions with the electrolyte. Knowing what it really looks will give them a new way to improve next-gen battery design. Lithium metal batteries could store […]

Watching Batteries Work
February 20, 2014 | 1 Comment
Researchers at the Oak Ridge National Laboratory (ORNL) can image and measure electrochemical processes in batteries in real time and at nanoscale resolution. Using a new microscopy method scientists watch a miniature electrochemical liquid cell that is placed in a transmission electron microscope to study an enigmatic phenomenon in lithium-ion batteries called the solid electrolyte […]
