This layer addresses previous issues, such as the growth of needle-like zinc structures\u2014known as zinc dendrites\u2014as well as unwanted chemical side reactions that trigger hydrogen formation and corrosion.<\/p>\n<p>The research team, led by Professor Roland Fischer, Chair of Inorganic and Metal-Organic Chemistry at the TUM School of Natural Sciences<a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/aenm.202403030\" target=\"_blank\" rel=\"noopener\">, uses a unique material for this purpose<\/a>: a porous organic polymer called TpBD-2F.<\/p>\n<p>This material forms a stable, ultra-thin, and highly ordered film on the zinc anode, allowing zinc ions to flow efficiently through nano channels while keeping water away from the anode.<\/p>\n<h3>Zinc batteries as a cost-effective alternative to lithium-ion batteries<\/h3>\n<p>Da Lei, PhD student and lead author of the research, explained: \u201cZinc-ion batteries with this new protective layer <a href=\"https:\/\/www.innovationnewsnetwork.com\/aqueous-zinc-on-batteries-a-promising-lithium-ion-alternative\/51188\/\">could replace lithium-ion batteries in large-scale energy storage<\/a> applications, such as in combination with solar or wind power plants.<\/p>\n<p>\u201cThey last longer, are safer, and zinc is both cheaper and more readily available than lithium.\u201d<\/p>\n<p>While lithium remains the first choice for mobile applications like electric vehicles and portable devices, its higher costs and environmental impact make it less attractive for large-scale energy storage.<\/p>\n<p>Professor Fischer added: \u201cWe have shown that the chemical approach developed to extend zinc battery lifespan not only works but is also controllable.<\/p>\n<p>\u201cAs fundamental researchers, we are primarily interested in new scientific principles\u2014and here we have discovered one.\u201d<\/p>\n<p>Fischer concluded: \u201cWe have already developed a first prototype in the form of a button cell. I see no reason why our findings couldn\u2019t be translated into larger applications.<\/p>\n<p>\u201cNow, it&#8217;s up to engineers to take up the idea and develop appropriate production processes.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>TUM researchers have developed a new chemical method to increase zinc battery lifespan and improve energy
