The powder adheres to the anode and becomes a thin, lithiated coating that effectively prevents the formation of damaging dendrites.<\/p>\n<p>A powder of phosphorus and sulfur ground into the surface of lithium metal foil demonstrated its surface energy can be tuned without the need for toxic solvents. Anodes so modified and paired with lithium-iron-phosphate-oxide cathodes in test cells showed they retained 70% more capacity after 340 charge-discharge cycles than off-the-shelf batteries.<\/p>\n<p>The study <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>ears in <i>Advanced Materials<\/i>.<\/p>\n<p>&#8220;This would simplify the manufacture of high-capacity batteries while greatly improving them,&#8221; Tour said. &#8220;Sanding these powdered solids into a lithium metal anode dramatically reduces dendrite formation that can short circuit a battery, as well as the accelerated consumption of the materials.&#8221; <\/p>\n<p>Lead author and Rice graduate student Weiyin Chen and his lab colleagues applied the necessary elbow grease to test a variety of powder candidates on their electrodes. They first brushed the surface to give it texture, then brushed in powder to create the fine film that reacts with the lithium metal and forms a solid passivation layer.<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/brushing-thin-films-on-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/2022\/brushing-thin-films-on-1.jpg\" data-sub-html=\"Brushing metal powders into the surface of lithium anodes shows promise to curtail the threat of dendrites that damage recyclable batteries, according to scientists at Rice University.

Fred Higgs III that sanding certain powders into surfaces can make them superhydrophobic, or highly resistant to water.<\/p>\n<p>Co-authors of the paper are Rice alums John Li and Duy Luong; graduate students Jacob Beckham, Nghi La and Jianan Xu, and academic visitor Victor Li.
