Presenter: Guiomar Hern\u00e1ndez Abstract<\/strong><\/p>\n\n\n\n \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nSafety and cycling stability are still the main\nconcerns towards developing high energy density lithium metal batteries. In\nthis regard, electrolytes play an important role as they are able to form a\nstable passivating layer called solid electrolyte interphase (SEI). This layer\nis able to suppress continuous electrolyte degradation improving the\ncyclability of the batteries. Although fluoroethylene carbonate (FEC) has been\nfound to be a particularly effective SEI-forming additive, its combination with\nthe conventional LiPF6 salt accelerates the electrolyte degradation. Herein we\nhave study the trigger and mechanism of such degradation with liquid- and\nsolid-state NMR. Furthermore, additives to avoid such degradation have been\ninvestigated to improve chemical and electrochemical stability of electrolytes\nto be used in LiNi1\/3Mn1\/3Co1\/3O2\/Li metal batteries at high temperatures.\n\n\n\n<\/p>\n\n\n\n Full conference program<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Presenter: Guiomar Hern\u00e1ndezTitle: Fluoroethylene Carbonate Containing Electrolytes: Origin of Poor Shelf Life and Its MitigationAffiliation: Uppsala University Abstract Safety and … Continue reading Fluoroethylene Carbonate Containing Electrolytes: Origin of Poor Shelf Life and Its Mitigation<\/span><\/a><\/p>\n","protected":false},"author":13,"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-1230","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\/1230","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\/13"}],"replies":[{"embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/comments?post=1230"}],"version-history":[{"count":4,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts\/1230\/revisions"}],"predecessor-version":[{"id":1299,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts\/1230\/revisions\/1299"}],"wp:attachment":[{"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/media?parent=1230"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/categories?post=1230"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/tags?post=1230"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
