Redox\u2011flow batteries accumulate electrical energy in chemical compounds that are then dissolved in an electrolyte. This technology offers a remarkably promising alternative to lithium\u2011ion batteries as stationary energy storage.<\/p>\n
A team of researchers, led by Prof. Dr.\u00a0Ingo Krossing\u00a0<\/strong>from the Institute of Inorganic and Analytical Chemistry at the University of Freiburg has successfully developed a non-aqueous All\u2011Manganese Flow battery (All-MFB) that uses the more sustainable manganese \u2013 an abundant chemical element with a long cycle life \u2013 as its active material.<\/p>\n The Freiburg team has recorded their research findings<\/a> in the latest edition of\u00a0Advanced Energy Materials<\/em>, under the title \u201cInvestigations toward a Non-Aqueous Hybrid Redox-Flow Battery with a Manganese-Based Anolyte and Catholyte\u201d.<\/p>\n Active materials are chemical substances that are necessary in order to store energy in batteries. The researchers have now effectively replaced the previous active material \u2013 the element vanadium \u2013 with manganese, a much more abundant element.<\/p>\n Krossing, along with his research team, has implemented a novel method to apply the sustainable manganese in the battery: until now, coupling the deposition of manganese in its elemental form with the oxidation of manganese in the oxidation state +II to manganese +III had not been used to store electrochemical energy.<\/p>\n The newly-developed redox-flow batteries attain an energy density approximately twice as high compared to the typical redox\u2011flow battery with vanadium.<\/p>\n \u201cWith the electrolytes presented in our publication, energy densities of up to 74 Wh L\u20131<\/sup>\u00a0are possible,\u201d explained Krossing. \u201cThis was already far better in the first try than the energy density of the vanadium redox\u2011flow battery, which has been researched since 1978.\u201d Further optimisation of the battery is necessary, according to the Freiburg chemist, \u201cbut this system describes a new and highly promising design for sustainable stationary energy storage<\/a>.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":" Researchers at Albert-Ludwigs-Universit\u00e4t Freiburg have developed a novel method for producing hybrid redox-flow batteries with a long battery life, with promising potential for sustainable stationary energy storage.<\/p>\n","protected":false},"author":13,"featured_media":12232,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[24433,785],"tags":[649,24161,24134],"acf":[],"yoast_head":"\n
