Presenter:\u00a0Dr. Christian Elkj\u00e6r Abstract<\/strong><\/p>\n\n\n\n Li1<\/sub>Ni0.5<\/sub>Mn1.5<\/sub>O4<\/sub> is a promising cobalt free cathode material that offers high energy density at a competitive price. Due to the high operating voltage of 4.7 V vs. Li\/Li+, LNMO based batteries however suffers from limited lifetime due to instabilities of the various components in the cell. At Haldor Tops\u00f8e we develop LNMO and have focused much of our research in the detailed understanding of the structure and chemistry of the cathode material by using our existing facilities for microstructural characterization of catalyst materials by e.g. XRD and electron microscopy. In this presentation, we will show how the size of the spinel lattice is closely correlated with the amount of Mn3+<\/sup> in the structure as measured electrochemically and how this is related to the composition of the LNMO as measured by electron microscopy. Further, these parameters have a profound influence on the integrity of the cathode material, and thereby the cycling stability, in half-cells. <\/p>\n\n\n\n Full conference program<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Presenter:\u00a0Dr. Christian Elkj\u00e6rTitle: Towards Automatic Disassembly of EV-Batteries Affiliation: Haldor Topsoe A\/S Abstract Li1Ni0.5Mn1.5O4 is a promising cobalt free cathode … Continue reading Improving the cycling stability of high voltage LNMO by tailoring structure and composition<\/span><\/a><\/p>\n","protected":false},"author":47,"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-1949","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\/1949","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\/47"}],"replies":[{"embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/comments?post=1949"}],"version-history":[{"count":2,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts\/1949\/revisions"}],"predecessor-version":[{"id":1954,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts\/1949\/revisions\/1954"}],"wp:attachment":[{"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/media?parent=1949"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/categories?post=1949"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/tags?post=1949"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
