Abstract: front page image
(EN)This lithium ion secondary battery is provided with: a positive electrode that contains a spinel-type lithium-nickel-manganese composite oxide, which serves as a positive electrode active material, and amorphous carbon and graphite, which serve as conductive agents; and a negative electrode that contains, as a negative electrode active material, an active material where lithium ions are intercalated and deintercalated at a potential of 1.2 V or more with respect to the lithium potential.
(FR)L'invention concerne une batterie rechargeable au lithium-ion comprenant : une électrode positive qui contient un oxyde composite de lithium-nickel-manganèse de type spinelle, qui sert de matériau actif d'électrode positive, et du carbone amorphe et du graphite, qui servent d'agents conducteurs ; et une électrode négative qui contient, en tant que matériau actif d'électrode négative, un matériau actif dans lequel des ions lithium sont intercalés et désintercalés à un potentiel de 1,2 V ou plus par rapport au potentiel de lithium.
