Abstract:
(EN) The objective of the present invention is to provide: a positive electrode active material which is capable of suppressing the generation of a gas associated with charge and discharge in a lithium secondary battery, and which is especially capable of suppressing the generation of a gas associated with charge and discharge even in cases where the working voltage of the lithium secondary battery is high; a positive electrode which uses this positive electrode active material; a lithium secondary battery; a method for producing this positive electrode active material; and a method for manufacturing a lithium secondary battery. The present invention is a positive electrode active material for lithium secondary batteries, which contains a coated positive electrode active material that is obtained by directly covering the surface of a positive electrode active material with lithium metaphosphate.
(FR) L'objectif de la présente invention est de fournir : un matériau actif d'électrode positive permettant de supprimer la génération d'un gaz associé à la charge et la décharge dans une pile rechargeable au lithium, et permettant notamment de supprimer la génération d'un gaz associé à la charge et la décharge même dans le cas où la tension de fonctionnement de la pile rechargeable au lithium est élevée ; une électrode positive qui utilise ce matériau actif d'électrode positive ; une pile rechargeable au lithium ; un procédé de préparation dudit matériau actif d'électrode positive ; et un procédé de fabrication d'une pile rechargeable au lithium. La présente invention concerne un matériau actif d'électrode positive pour piles rechargeables au lithium qui contient un matériau actif d'électrode positive revêtu qui est obtenu en recouvrant directement la surface d'un matériau actif d'électrode positive avec du métaphosphate de lithium.
