Cependant, jusqu&#039;\u00e0 pr\u00e9sent, les fabricants devaient choisir entre deux options\u00a0: permettre une charge ultra-rapide ou garantir une longue dur\u00e9e de vie aux cellules. La charge rapide d\u00e9grade la structure des nanofeuilles, ce qui r\u00e9duit leur dur\u00e9e de vie par rapport \u00e0 la technologie LFP \u00e9prouv\u00e9e.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Une \u00e9quipe de chercheurs chinois a peut-\u00eatre trouv\u00e9 une solution \u00e0 ce probl\u00e8me. Ils ont mis au point une anode compos\u00e9e de nanofeuilles de dioxyde de titane d&#039;environ 10 nanom\u00e8tres, formant des sph\u00e8res creuses \u00e0 double coque. L&#039;innovation majeure r\u00e9side dans un rev\u00eatement de graph\u00e8ne de seulement 0,4 nanom\u00e8tre d&#039;\u00e9paisseur, qui enveloppe chaque nanofeuille. Un simple m\u00e9lange de graph\u00e8ne avec d&#039;autres mat\u00e9riaux n&#039;a pas donn\u00e9 les m\u00eames r\u00e9sultats, tandis qu&#039;une couche protectrice directe a permis d&#039;accro\u00eetre la conductivit\u00e9 \u00e9lectrique.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Les r\u00e9sultats des tests sont tr\u00e8s prometteurs. \u00c0 un taux de charge rapide de 10C, correspondant th\u00e9oriquement \u00e0 environ six minutes, l&#039;anode a conserv\u00e9 une capacit\u00e9 de 131 mAh\/g m\u00eame apr\u00e8s 10\u00a0000 cycles. \u00c0 un taux de 100C, soit une charge d&#039;environ 36 secondes, elle a atteint une capacit\u00e9 de 121 mAh\/g. En comparaison, les nanofeuilles non prot\u00e9g\u00e9es se sont d\u00e9grad\u00e9es apr\u00e8s environ 400 cycles. Les ions sodium, plus volumineux, exercent une forte contrainte sur la surface de l&#039;anode lors de la charge rapide, et la couche protectrice de graph\u00e8ne emp\u00eache la formation de fissures et les r\u00e9actions excessives avec l&#039;\u00e9lectrolyte.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Toutes ces mesures ont \u00e9t\u00e9 r\u00e9alis\u00e9es, bien entendu, en laboratoire. Par ailleurs, l&#039;anode fonctionne \u00e0 une tension moyenne plus \u00e9lev\u00e9e que les anodes classiques en carbone dur, ce qui peut r\u00e9duire la densit\u00e9 \u00e9nerg\u00e9tique globale de la batterie. Bien entendu, cette nouvelle technologie devra \u00eatre valid\u00e9e sur des cellules et des packs de batteries de plus grande taille, con\u00e7us pour la production commerciale, avant de pouvoir \u00eatre utilis\u00e9e dans les v\u00e9hicules \u00e9lectriques de s\u00e9rie.<\/p>","protected":false},"excerpt":{"rendered":"<p>Natrij-ionske baterije postajajo vse privla\u010dnej\u0161a alternativa litijevim, saj temeljijo na cenovno dostopnej\u0161ih in bolj raz\u0161irjenih surovinah, ponujajo ve\u010djo varnost ter dobro delujejo tudi pri nizkih temperaturah.
