Abstract

La présente invention porte sur une batterie secondaire au lithium qui comprend : une électrode positive ; une électrode négative qui fait face à l'électrode positive ; un séparateur disposé entre l'électrode positive et l'électrode négative ; et un électrolyte non aqueux. L'électrode négative a un collecteur de courant d'électrode négative et une languette d'électrode négative électriquement connectée au collecteur de courant d'électrode négative. Dans l'électrode négative, du lithium métallique est déposé sur le collecteur de courant d'électrode négative pendant la charge, et du lithium métallique est dissous dans l'électrolyte non aqueux pendant la décharge. La languette d'électrode négative contient de l'acier inoxydable au moins dans une partie de connexion avec le collecteur de courant d'électrode négative.
