Presenter:\u00a0Filippo Fenini Abstract<\/strong><\/p>\n\n\n\n Aqueous Organic redox flow batteries (AORFB) are emerging\nas large-scale storage technology, as organic redox species have the potential\nto be a low cost commodity with broad geographical availability. Capacity fade\nmechanisms in AORFB are attributable to decomposition pathways of the active\nmolecules. Such reactions are often catalyzed by either basic or acidic\nenvironment, yet most of AORFB reported are operated in such conditions, to\nachieve the highest solubility (energy density). Here we report a close-to-neutral\norganic-inorganic battery with excellent cyclability and high durability.\n2,7-AQDS is used as negative electrolyte and Fe(CN)64- as positive electrolyte.\nIt will be shown how the energy density of the negative side can be increased\nby the addition of an inexpensive co-electrolyte. The tests indicate how time\nrather than number of cycles is responsible of the capacity fade. After 1000 h\nof cycling, the negative side of the AORFB still exhibit high capacity\nretent ion.<\/p>\n\n\n\n Full conference program<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Presenter:\u00a0Filippo FeniniTitle: Close-to-neutral operation enables high capacity retention: long-term testing of an aqueous organic-inorganic redox flow battery Affiliation: Aarhus University … Continue reading Close-to-neutral operation enables high capacity retention: long-term testing of an aqueous organic-inorganic redox flow battery<\/span><\/a><\/p>\n","protected":false},"author":28,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"page-templates\/full-width.php","format":"standard","meta":{"footnotes":""},"categories":[52,56],"tags":[],"class_list":["post-1228","post","type-post","status-publish","format-standard","hentry","category-nordbatt2019","category-oral-presentation"],"_links":{"self":[{"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts\/1228","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/users\/28"}],"replies":[{"embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/comments?post=1228"}],"version-history":[{"count":3,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts\/1228\/revisions"}],"predecessor-version":[{"id":1296,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts\/1228\/revisions\/1296"}],"wp:attachment":[{"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/media?parent=1228"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/categories?post=1228"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/tags?post=1228"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
