These deposits were carried out on planar silicon substrates but also on complex three-dimensional architectures as shown in the figure below. This particular architecture allows to deploy an exchange surface 50 to 80 times larger between the electrodes compared to an equivalent planar micro-battery. The final objective of this thesis work was to show the fabrication of 3D all-solid micro-batteries in Lithium-ion technology.<\/p>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-13ewzjw-da1815c7a8a572fcf64b974c4c4df7b7\">\n.av_font_icon.av-13ewzjw-da1815c7a8a572fcf64b974c4c4df7b7{\ncolor:#ef790b;\nborder-color:#ef790b;\n}\n.av_font_icon.av-13ewzjw-da1815c7a8a572fcf64b974c4c4df7b7 .av-icon-char{\nfont-size:20px;\nline-height:20px;\n}\n<\/style>\n<span  class='av_font_icon av-13ewzjw-da1815c7a8a572fcf64b974c4c4df7b7 avia_animate_when_visible av-icon-style- avia-icon-pos-left avia-icon-animate'><span class='av-icon-char' aria-hidden='true' data-av_icon='\ue842' data-av_iconfont='entypo-fontello' ><\/span><\/span>\n<p><a href=\"https:\/\/sciences-technologies.univ-lille.fr\/actualite\/\/laureat-prix-these-cnano2020\/\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>Read more +<\/strong><\/a><\/p>\n<\/div><\/section><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-11v0kgd-37a18114e9f0a449e88f53526d3d2891\">\n.flex_column.av-11v0kgd-37a18114e9f0a449e88f53526d3d2891{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-11v0kgd-37a18114e9f0a449e88f53526d3d2891 av_one_half  avia-builder-el-3  el_after_av_one_full  el_before_av_one_half  first flex_column_div av-zero-column-padding  column-top-margin'     ><section  class='av_textblock_section av-khetkgye-2e46e036b1b2a234bc13a43308cdae2d'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p style=\"text-align: center;\"><em><strong><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/11\/visuelA.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-medium wp-image-43122\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/11\/visuelA-300x188.jpg\" alt=\"\" width=\"300\" height=\"188\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/11\/visuelA-300x188.jpg 300w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/11\/visuelA-16x10.jpg 16w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/11\/visuelA.jpg 452w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a>Figure 1.
