Honda Motor vise \u00e0 doubler l’autonomie de ses voitures \u00e9lectriques d’ici la fin des ann\u00e9es 2020 lorsqu’elles commenceront \u00e0 adopter des batteries \u00e0 l’\u00e9tat solide, un nouveau type de source d’\u00e9nergie en cours de d\u00e9veloppement, a d\u00e9clar\u00e9 mercredi le responsable de son unit\u00e9 de recherche.<\/p>\n
Les batteries tout solide, qui remplacent les batteries lithium-ion \u00e0 l’\u00e9tat liquide, permettront de doubler l’autonomie d’ici la fin de la d\u00e9cennie et de la multiplier par 2,5 d’ici les ann\u00e9es 2040, a d\u00e9clar\u00e9 Keiji Otsu, pr\u00e9sident du d\u00e9partement R&D de Honda.<\/p>\n
<\/div>\n
Les constructeurs automobiles et les fournisseurs de batteries du monde entier ont d\u00e9voil\u00e9 des plans de d\u00e9veloppement de batteries \u00e0 l’\u00e9tat solide, pr\u00e9sent\u00e9es comme une technologie cl\u00e9 pour fabriquer des v\u00e9hicules \u00e9lectriques plus durables, plus s\u00fbrs et moins chers, dans un contexte de ralentissement de la croissance du march\u00e9 des v\u00e9hicules \u00e9lectriques.<\/p>\n
“Il s’agit de changer la donne dans l’\u00e8re des v\u00e9hicules \u00e9lectriques”, a d\u00e9clar\u00e9 M. Otsu aux journalistes pr\u00e9sents sur la ligne pilote de production de batteries \u00e0 l’\u00e9tat solide de Honda \u00e0 Tochigi, au nord de Tokyo. Honda investit 43 milliards de yens (277 millions de dollars) dans cette ligne pilote, dont pr\u00e8s de la moiti\u00e9 est financ\u00e9e par des subventions du gouvernement japonais.<\/p>\n
Honda commencera \u00e0 exploiter la ligne pilote en janvier, avec pour objectif de r\u00e9duire la taille des batteries de 50 %, leur poids de 35 % et leur co\u00fbt de 25 % par rapport aux niveaux actuels au cours des cinquante prochaines ann\u00e9es, a d\u00e9clar\u00e9 M. Otsu.<\/p>\n
Honda pr\u00e9voit de porter sa production annuelle de v\u00e9hicules \u00e9lectriques \u00e0 plus de 2 millions d’unit\u00e9s d’ici \u00e0 2030. Elle vise \u00e9galement un taux de vente global de 40 % pour les VE et les v\u00e9hicules \u00e0 pile \u00e0 combustible en 2030, et de 100 % en 2040.<\/p>\n
Nissan Motor, partenaire strat\u00e9gique de Honda, d\u00e9veloppe \u00e9galement des batteries \u00e0 l’\u00e9tat solide et pr\u00e9voit de mettre en service sa ligne pilote en mars.<\/p>\n
“Il y a peut-\u00eatre des domaines dans lesquels nous pouvons travailler ensemble”, a d\u00e9clar\u00e9 M. Otsu, sugg\u00e9rant la possibilit\u00e9 d’un approvisionnement commun en mat\u00e9riaux.<\/p>\n
Honda n’a “aucune raison de refuser” la vente \u00e0 l’ext\u00e9rieur de ses batteries \u00e0 l’\u00e9tat solide si cela est mutuellement b\u00e9n\u00e9fique pour elle et ses partenaires, a ajout\u00e9 M. Otsu.<\/p>\n
Toyota Motor, le plus grand constructeur automobile mondial en termes de ventes, cherche \u00e0 commercialiser des batteries \u00e0 l’\u00e9tat solide en 2027-2028 en partenariat avec le raffineur de p\u00e9trole Idemitsu Kosan.<\/p>\n
