After this phase ends, we start qualifying our material for introduction in the product lines,\u201d he said.<\/span><span>&nbsp;<\/span><\/p>\n<p><span>LeydenJar claims that batteries equipped with its anodes could charge a phone to 80% in less than seven minutes. And the tech could make laptop batteries 40% smaller, allowing for thinner designs. In drones, it could almost double the range.<\/span><\/p>\n<p><span>The company plans to build a second, giga-scale factory, PlantTwo, in 2028.&nbsp;<\/span><\/p>\n<h2><b>Secret silicon sauce<\/b><\/h2>\n<p><span>Silicon was actually used to make anodes before graphite was. But technical challenges have largely kept silicon anodes to the confines of the lab. The problem is that silicon swells and breaks easily when charged, reducing the lifespan of the batteries it\u2019s used in and even potentially making them unsafe.&nbsp;<\/span><\/p>\n<p><span>LeydenJar has fixed this issue by <\/span><span>growing tiny columns of silicon, several micrometers thick, on copper foil. In contrast to a solid sheet of silicon, the spaces in between these columns allow swelling to take place within the material itself, which keeps it from impacting the cell as a whole.&nbsp;&nbsp;<\/span><\/p>\n<p><span>The sponge-like columns are porous and flexible, and lead to a high anode loading area \u2014 which means more places for electrons to cling onto. This translates to an energy density up to 1.350 Wh\/l or 390 Wh\/kg. That\u2019s up to 70% more energy storage than a graphite anode equivalent.&nbsp;&nbsp;<\/span><\/p>\n<figure class=\"post-image post-mediaBleed aligncenter\"><img decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-1404531 js-lazy\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2024\/03\/LeydenJar-Silicon-Anode-Foil.jpg\" alt=\"leydenjar silicon anode foil\" width=\"1640\" height=\"1093\" sizes=\"(max-width: 1640px) 100vw, 1640px\" data-srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2024\/03\/LeydenJar-Silicon-Anode-Foil.jpg 1640w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2024\/03\/LeydenJar-Silicon-Anode-Foil-280x187.jpg 280w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2024\/03\/LeydenJar-Silicon-Anode-Foil-203x135.jpg 203w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2024\/03\/LeydenJar-Silicon-Anode-Foil-405x270.jpg 405w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2024\/03\/LeydenJar-Silicon-Anode-Foil-1536x1024.jpg 1536w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2024\/03\/LeydenJar-Silicon-Anode-Foil-796x531.jpg 796w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2024\/03\/LeydenJar-Silicon-Anode-Foil-1592x1061.jpg 1592w\"><figcaption><a href=\"https:\/\/thenextweb.com\/news\/dutch-battery-startup-silicon-anodes-eindhoven-leydenjar#\" data-url=\"https:\/\/twitter.com\/intent\/tweet?url=https%3A%2F%2Feditorial.thenextweb.com%2Fdeep-tech%2F2024%2F03%2F05%2Fdutch-battery-startup-silicon-anodes-eindhoven-leydenjar%2F&amp;via=thenextweb&amp;related=thenextweb&amp;text=Check out this picture on: LeydenJar\u2019s silicon anode foil is up to 10x thinner than the graphite equivalent.
