\u00bb<\/h4>\n<p>Maxime has designed miniatures batteries based on the alloy of lithium materials. These so-called solid state batteries are developed in 3D architecture, which gives them a high storage capacity.<\/p>\n<blockquote>\n<p>\u00ab The challenge of the years 2010-2020 is to design batteries with high energy densities in very small spaces. We can take the image of a lung: its complex tree-like structure, composed of alveoli ending in capillaries, allows an optimal gas exchange with the air.\u00a0\u00bb<\/p>\n<\/blockquote>\n<p>His project dedicates several years of research on the subject. His predecessor had worked in 3D architecture but on a half battery. Now, a battery is composed of (at least) 6 layers of materials.<\/p>\n<blockquote>\n<p>\u00ab Thanks to my thesis work, I have laid the final brick. With the stacking of all the layers of materials in 3D, I have validated the fabrication of a complete device! \u00bb<\/p>\n<\/blockquote>\n<p>After an integrated preparatory school at ISEN, Maxime continued his engineering studies and obtained a master\u2019s degree in communicating systems at the University of Lille with a major in nano and microtechnologies, where he developed a strong interest in energy storage and conversion. There, he met Christophe Lethien, his thesis director, who steered him towards promising themes.<br \/>\nFor Maxime, the challenge of his research lay in the design of all-solid batteries because the electrolyte, the conductive substance that separates two electrodes and allows the exchange of ions, is composed of liquid solvents.<\/p>\n<blockquote>\n<p>\u00ab One difficulty was to carry out all the material synthesis on a 3D architecture that uses advanced deposition techniques called \u00ab atomic layer deposition or ALD. \u00bb<\/p>\n<\/blockquote>\n<p>Maxime\u2019s work is in the maturation phase. He wishes to continue working in the field of renewable energy. He plans to extend his prototype to a global project of energy storage systems for other types of batteries or components. The result is a startup with a future, housed at IEMN!<\/p>\n<\/div><\/section><\/p><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-kq28xf4t-e65d638837ca1e6e3f489ea930ed56fc\">\n#top .hr.av-kq28xf4t-e65d638837ca1e6e3f489ea930ed56fc{\nmargin-top:9px;\nmargin-bottom:30px;\n}\n.hr.av-kq28xf4t-e65d638837ca1e6e3f489ea930ed56fc .hr-inner{\nwidth:50px;\nmax-width:45%;\n}\n.hr.av-kq28xf4t-e65d638837ca1e6e3f489ea930ed56fc .av-seperator-icon{\ncolor:#b02b2c;\n}\n<\/style>\n<div  class='hr av-kq28xf4t-e65d638837ca1e6e3f489ea930ed56fc hr-custom  avia-builder-el-9  el_after_av_four_fifth  el_before_av_three_fourth  hr-center hr-icon-yes'><span class='hr-inner inner-border-av-border-fat'><span class=\"hr-inner-style\"><\/span><\/span><span class='av-seperator-icon' aria-hidden='true' data-av_icon='\ue808' data-av_iconfont='entypo-fontello'><\/span><span class='hr-inner inner-border-av-border-fat'><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-w92e9k-34e5e5967e03de80190cf7a6b85e581e\">\n@keyframes av_boxShadowEffect_av-w92e9k-34e5e5967e03de80190cf7a6b85e581e-column {\n0%   { box-shadow:  0 0 0 0 #745f7e; opacity: 1; }\n100% { box-shadow:  0 0 15px 0 #745f7e; opacity: 1; }\n}\n.flex_column.av-w92e9k-34e5e5967e03de80190cf7a6b85e581e{\ntransform:scale(1.1);\nz-index:5;\nbox-shadow: 0 0 15px 0 #745f7e;\nborder-radius:8px 8px 8px 8px;\npadding:1px 1px 1px 1px;\nbackground-color:#edeae6;\nbackground:radial-gradient( #edeae6, #c9c9c9 );\n}\n<\/style>\n<div  class='flex_column av-w92e9k-34e5e5967e03de80190cf7a6b85e581e av_three_fourth  avia-builder-el-10  el_after_av_hr  el_before_av_hr  first flex_column_div av-animated-generic pop-up shadow-not-animated'     ><section  class='av_textblock_section av-kpo3ar28-a126c8a62f12c46bc9efe9d3084dc730'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><h6><span style=\"color: #000000;\">\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-168fn08-1241fff7a210d1cd7badc4d8703be219\">\n.av_font_icon.av-168fn08-1241fff7a210d1cd7badc4d8703be219 .av-icon-char{\nfont-size:20px;\nline-height:20px;\n}\n<\/style>\n<span  class='av_font_icon av-168fn08-1241fff7a210d1cd7badc4d8703be219 avia_animate_when_visible av-icon-style- avia-icon-pos-left av-no-color avia-icon-animate'><span class='av-icon-char' aria-hidden='true' data-av_icon='\ue85e' data-av_iconfont='entypo-fontello' ><\/span><\/span>You have both contributed to a lot of micro and nanotechnology developments in cleanrooms.

This material is found naturally in graphite crystals. Researchers discovered it in 2004 by using the adhesive strip of a roll of scotch tape to exfoliate layers of graphite. \u00ab Its characteristics are unique: both strong and light, an excellent thermal conductor, deformable and transparent; however, it is difficult to synthesize and couple with other materials. <span style=\"color: #000000;\">\" <\/span>Nathali got around the difficulty by creating an artificial material that mimics the characteristics of graphene:<\/p>\n<blockquote>\n<p>\u00ab We made a honeycomb structure by making holes in III-V semiconductors to mimic the organization of carbon atoms in graphene, based on quantum physics. <span style=\"color: #000000;\">\"<\/span><\/p>\n<\/blockquote>\n<p>To observe quantum phenomena, one must work at a microscopic scale such that the electrons behave mainly as waves.
