A National Institute for Materials Science (NIMS) research team has succeeded in substantially improving the cycling performance of a lithium metal battery by developing a mechanically very strong polymeric gel electrolyte and integrating it into the battery as a layer to protect the lithium metal anode. This achievement may greatly facilitate efforts to put lithium metal anodes—a potentially very high performance anode material—into practical use.

 

Today’s society is rapidly transforming through the widespread use of digital technologies, the increasing popularity of electric vehicles and the growing use of renewable energy. These shifts have created a steadily rising demand for higher performance lithium secondary batteries. Lithium metal anodes have very large theoretical capacities and low working potentials. However, they also have an issue: the process of lithium dissolution and deposition, which occurs as the battery is charged and discharged, is prone to deterioration, shortening the batteries’ charge-discharge cycle lives and posing safety concerns. New technologies capable of stabilizing the charge-discharge cycles of secondary batteries equipped with lithium metal anodes are therefore needed.

 

This research team developed mechanically tough and stretchable gel electrolytes formed by an organic solvent electrolyte containing a high concentration of lithium salts and a hydrogen-bonded polymer. The team then integrated this gel electrolyte as an artificial layer to protect the lithium metal anode. Experiments demonstrated that the addition of the protective layer significantly improved the battery’s cycling stability.

 

In future research, the research team plans to optimize the gel electrolyte for use as a protective layer and evaluate the layer’s effectiveness when combined with various types of electrolytes and next-generation cathodes. The team hopes that this technology will contribute to efforts to put next-generation lithium secondary batteries equipped with lithium metal anodes into practical use.

Cameras used in harsh environments must be designed in a way that prevents temperature swings from influencing their optical performance. New research demonstrates that accounting for the exact lens mounting structure used is a critical step in ensuring that lens systems remain robust to temperature changes. Eric M. Schiesser from Synopsys, Inc. will present the new research at the Optica Design and Fabrication Conference, which will take place 04 – 08 June 2023 in Quebec City, Canada. “Most optical systems – from the camera in your smartphone to the eyes of the Mars rover - are used over a range of temperatures.  To keep the image sharp ...

New study led by Brown researchers sheds light on incidental findings in lung cancer screening

2023-05-09
PROVIDENCE, R.I. [Brown University]—When patients receive a low-dose computed tomography screen for lung cancer, doctors can see more than just the lungs. The screening test often picks up abnormalities or potentially “significant incidental findings” (SIFS) not associated with lung cancer. A new study led by Ilana Gareen, an associate professor of epidemiology at the Brown University School of Public Health, and published in JAMA Internal Medicine, highlights the need for proper reporting and management of these findings to reduce mortality, health care costs and unnecessary ...

The team reports in the journal Genetics in Medicine that they were able to find variants in this gene in patients whose neurodevelopment disorders had previously gone undiagnosed. The research also revealed that the mutations disrupt the way the MRTFB protein controls other genes in the cell and this cascades to affect hundreds of other genes. “We identified ...

Change in breast density over time linked to cancer risk

2023-05-09
Many middle-aged and older women get mammograms every one to two years to screen for breast cancer, as recommended by their doctors. A study by researchers at Washington University School of Medicine in St. Louis indicates that previous mammograms hold underutilized data that could help identify women at high risk of breast cancer and even reveal which breast is likely to be affected. When doctors read mammograms, they assess breast density along with signs of cancer, comparing a woman’s previous mammograms to her most recent one to look for worrisome changes. But some changes are difficult to ...
