Coin cells are assembled and tested at room temperature, at elevated temperature and with high voltage cycling. They were also tested before and after washing and milling treatment. Secondly, the effect of lithiation on different precursors and their suitability for single crystal lithiation was investigated. Several NCM622 precursors were precipitated and their performance after different lithiation conditions was compared. Materials varied in particle size, particle size distribution, tap density and purity.<\/p>\n\n\n\n<p><a href=\"http:\/\/nordbatt.org\/2019\/posters\/\">Full list of posters<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Author: Marianna Hietaniemi Title: Comparison of single crystal and polycrystalline lithiation for NCM622 cathode materialsAffiliation: University of Oulu Abstract Single &hellip; <a href=\"http:\/\/nordbatt.org\/2019\/blog\/marianna-hietaniemi-comparison-of-single-crystal-and-polycrystalline-lithiation-for-ncm622-cathode-materials\/\" class=\"more-link\">Continue reading <span class=\"screen-reader-text\">Poster: Comparison of single crystal and polycrystalline lithiation for NCM622 cathode materials<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"nordbatt-wide.php","format":"standard","meta":{"footnotes":""},"categories":[52,59],"tags":[],"class_list":["post-1734","post","type-post","status-publish","format-standard","hentry","category-nordbatt2019","category-poster-presentation"],"_links":{"self":[{"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts\/1734","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\/2"}],"replies":[{"embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/comments?post=1734"}],"version-history":[{"count":2,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts\/1734\/revisions"}],"predecessor-version":[{"id":1763,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts\/1734\/revisions\/1763"}],"wp:attachment":[{"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/media?parent=1734"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/categories?post=1734"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/tags?post=1734"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
