Abstract:
(EN) The present invention relates to an electrode active material complex, having a core-shell structure, for a lithium secondary battery and to a method for producing the electrode active material complex and, more specifically, to an electrode active material complex, having a core-shell structure, for a lithium secondary battery, comprising: a core comprising an electrode active material; and a shell positioned on the surface of the core and comprising a lithium ion-conducting inorganic material. The electrode active material complex according to the present invention has 70% or more of the surface of the core surrounded by the shell comprising the lithium ion-conducting inorganic material by using a solution process, and thus exhibits excellent reaction stability with an electrolyte and has lithium ion conductivity, thereby enabling a higher capacity and a longer life of a lithium secondary battery.
(FR) La présente invention concerne un complexe de matériau actif d'électrode, possédant une structure coeur-coquille, pour une batterie secondaire au lithium et un procédé de production du complexe de matériau actif d'électrode et, plus spécifiquement, un complexe de matériau actif d'électrode, possédant une structure coeur-coquille, pour une batterie secondaire au lithium, comprenant : un coeur comprenant un matériau actif d'électrode ; et une coquille positionnée sur la surface du coeur et comprenant un matériau inorganique conducteur d'ions lithium. 70% ou plus de la surface du coeur du complexe de matériau actif d'électrode selon la présente invention entourée par la coquille comprend le matériau inorganique conducteur d'ions de lithium, grâce à un procédé de solution, présente ainsi une excellente stabilité de réaction avec un électrolyte et favorise la conductivité des ions lithium, ce qui permet d'augmenter la capacité et la durée de vie d'une batterie secondaire au lithium.
