The coating was developed by scientists at the US Department of Energy\u2019s Lawrence Berkeley National Laboratory. It is called HOS-PFM and ensures battery stability in addition to high charge and discharge rates by simultaneously conducting electrons and ions, as said by the laboratory in a press release.<\/p>\n\n\n\n<p>According to the senior scientist in Berkeley Lab\u2019s Energy Technologies Area, Gao Liu, \u201c<em>The advance opens up a new approach to developing EV batteries that are more affordable and easy to manufacture,<\/em>\u201d adding that \u201c<em>The coating also shows promise as a battery binder that could extend the life of a lithium-ion battery from an average of ten to about 15 years.<\/em>\u201d<\/p>\n\n\n\n<p>In order to demonstrate the superior properties of <strong>HOS-PFM<\/strong>, the team coated aluminum and silicon electrodes, after which performance testing was conducted. This type of coating is produced using a <strong>nontoxic<\/strong> polymer and will enable the usage of electrodes that contain silicon up to <strong>80%<\/strong>. This high silicon content could <strong>boost<\/strong> the energy density of <strong>Li-Ion<\/strong> batteries by a minimum of <strong>30%<\/strong>, making this type of battery more cost-competitive and more <strong>affordable<\/strong>, as opposed to those containing graphite.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<p class=\"flex-video\"><iframe loading=\"lazy\" title=\"Electric vehicle batteries could get big boost with new polymer coating\" width=\"600\" height=\"338\" src=\"https:\/\/www.youtube.com\/embed\/s85tYSNa1Q4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/p>\n\n<\/div><\/figure>\n\n\n\n<p>According to Liu, this could lead to <strong>increasing<\/strong> the availability of entry-level EVs, as a result of cheaper batteries. In addition, the experiments showed that HOS-PFM coating prevents degradation during battery cycling of silicon and aluminum-based electrodes and delivered high battery capacity over 300 cycles.<\/p>\n\n\n\n<p>The findings are described in the journal <em>Nature Energy<\/em>. The team plans to work with companies in order to advance <strong>HOS-PFM<\/strong> to mass manufacturing levels. This research was supported by the DOE Vehicle Technologies Office and by the Toyota Research Institute. Founded in <strong>1931<\/strong>, the researchers from the Berkeley Lab develop solutions for energy and environmental sustainability. Such projects are essential for solving EVs\u2019 relatively short driving range and battery life concerns.<\/p>\n\n\n\n<p><small><em>Article Source: <a href=\"https:\/\/newscenter.lbl.gov\/2023\/03\/07\/ev-batteries-new-polymer-coating\/\" target=\"_blank\" rel=\"noreferrer noopener\">Berkeley Lab<\/a><br>Image by <a href=\"https:\/\/pixabay.com\/users\/distelapparath-2726923\/?utm_source=link-attribution&amp;utm_medium=referral&amp;utm_campaign=image&amp;utm_content=4158594\" target=\"_blank\" rel=\"noreferrer noopener\">Markus Distelrath<\/a> from <a href=\"https:\/\/pixabay.com\/\/?utm_source=link-attribution&amp;utm_medium=referral&amp;utm_campaign=image&amp;utm_content=4158594\" target=\"_blank\" rel=\"noreferrer noopener\">Pixabay<\/a><\/em><\/small><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Electric vehicles (EVs) could benefit from new conductive polymer coating that can boost their Lithium-Ion (Li-Ion) batteries, and make them longer-lasting.
