43 millions de tonnes <\/h2>\n

La compagnie p\u00e9troli\u00e8re et gazi\u00e8re allemande Neptune Energy a d\u00e9couvert un \u00e9norme gisement de lithium \u00e0 Altmark, une r\u00e9gion situ\u00e9e entre Hambourg et Berlin. Il s’agit de 43 millions de tonnes d’\u00e9quivalent carbonate de lithium (LCE). Ce mat\u00e9riau ne peut pas \u00eatre utilis\u00e9 directement pour les batteries, car il doit d’abord \u00eatre purifi\u00e9. \u00c9tant donn\u00e9 que le LCE se compose d’environ 19 % de lithium pur, la d\u00e9couverte permet d’obtenir quelque 8,1 millions de tonnes de lithium utilisable. \u00c0 titre de comparaison, l’Australie et le Chili – les poids lourds actuels du march\u00e9 du lithium – produisent chacun entre 9 et 11 millions de tonnes. Gr\u00e2ce \u00e0 cette d\u00e9couverte, l’Allemagne se hisse d’un seul coup au premier rang mondial. <\/p>\n

Le jackpot pour l’industrie automobile allemande ?<\/h2>\n

Pour l’Allemagne, cette d\u00e9couverte n’est pas une surprise. Le pays poss\u00e8de les plus grands constructeurs automobiles du monde, mais d\u00e9pend principalement des importations pour les mati\u00e8res premi\u00e8res des batteries. Une batterie moyenne pour une voiture \u00e9lectrique contient environ 8 kg de lithium. Avec la nouvelle r\u00e9serve allemande, il y aurait th\u00e9oriquement assez de mati\u00e8re pour produire environ 1,01 milliard de batteries de v\u00e9hicules \u00e9lectriques. Ces chiffres sont \u00e0 prendre avec des pincettes, car l’extraction et la purification du lithium sont des processus complexes et co\u00fbteux, en particulier en Europe, o\u00f9 la r\u00e9glementation est tr\u00e8s lourde. Mais m\u00eame si une fraction seulement s’av\u00e8re exploitable, l’industrie europ\u00e9enne des batteries s’en trouvera consid\u00e9rablement stimul\u00e9e. <\/p>\n

Notes annexes et avenirs<\/h2>\n

Ensuite, il y a la course \u00e0 la technologie. Si le lithium est actuellement indispensable pour les batteries des VE, les travaux battent leur plein sur des alternatives telles que les batteries sodium-ion et les batteries \u00e0 semi-conducteurs<\/a>. Celles-ci pourraient \u00eatre moins ch\u00e8res, plus rapides \u00e0 recharger et extr\u00eamement durables. Mais tant que cette technologie n’est pas largement pr\u00eate, le lithium reste la cl\u00e9 de l’avenir \u00e9lectrique. Dans la vid\u00e9o<\/a> ci-dessous, nous vous en disons plus sur les batteries \u00e0 semi-conducteurs : <\/p>\n
