However, the practical application of ASSBs is still hampered by difficulties in controlling the interfaces between the solid electrolyte and the electrodes. Halide-based lithium ion conductors show promise but are not stable against negative Li or LixIny electrodes, hence the need to assemble ASSBs with a dual solid electrolyte design. In a collaborative work between the Coll\u00e8ge de France (Chaire du Solide et de L&rsquo;\u00e9nergie, Pr Jean-Marie Tarascon) and the IEMN (CSAM Group, Pr Christophe Lethien), a new strategy has been implemented to fight against the chemical incompatibility between two solid electrolytes within an ASSB. It consists in depositing a protective layer of nanometric thickness (from 1 to 2 nm) of Li3PO4 realized by Atomic Layer Deposition (ALD) between two solid electrolytes (Li3InCl6 and Li6PS5Cl). Thanks to this surface engineering process with highly conformal nanoscale films, ASSBs showing a dramatic retention of capacity over 400 cycles have been successfully assembled.<\/p>\n<p><a href=\"..\/wp-content\/uploads\/2023\/03\/batteries.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-57076 aligncenter\" style=\"display: block; margin-left: auto; margin-right: auto;\" src=\"..\/wp-content\/uploads\/2023\/03\/batteries.jpg\" alt=\"\" width=\"560\" height=\"264\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2023\/03\/batteries.jpg 560w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2023\/03\/batteries-300x141.jpg 300w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2023\/03\/batteries-18x8.jpg 18w\" sizes=\"auto, (max-width: 560px) 100vw, 560px\" \/><\/a><\/p>\n<\/div><\/section><\/p><\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":20,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[297],"tags":[],"class_list":["post-57067","post","type-post","status-publish","format-standard","hentry","category-newsletter"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/57067","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/users\/20"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/comments?post=57067"}],"version-history":[{"count":0,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/57067\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=57067"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/categories?post=57067"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/tags?post=57067"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
