Abstract

La présente invention concerne une batterie secondaire au lithium-ion qui est pourvue d'une électrode positive, d'une électrode négative et d'un séparateur qui est agencé entre l'électrode positive et l'électrode négative. L'électrode positive est pourvue d'une couche de matériau actif d'électrode positive qui contient un matériau actif d'électrode positive, et le matériau actif d'électrode positive est un oxyde métallique contenant du lithium et dont le réseau unitaire est représenté par la formule générale (1) LiFe1-xZrxP1-ySiyO4 (où 0 < x < 1 et 0 < y < 1). Le réseau unitaire a des constantes de réseau de 10,326 ≤ a ≤ 10,335, 6,006 ≤ b ≤ 6,012 et 4,685 ≤ c ≤ 4,714. Le séparateur a une fraction de vide qui est supérieure ou égale à celle de la couche de matériau actif d'électrode positive.
