Abstract:
(EN) Provided is positive electrode active material for a lithium secondary battery, the positive electrode active material comprising vanadium oxide doped with zirconium (Zr) ions.The vanadium oxide is doped with 0.1-10 mol% zirconium ions with respect to the former. By applying the positive electrode active material for a lithium secondary battery to same, elution of vanadium from the positive electrode is controlled, and consequently, the lifespan of the battery is extended.
(FR) L'invention concerne un matériau actif d'électrode positive pour un accumulateur au lithium, le matériau actif d'électrode positive comprenant de l'oxyde de vanadium dopé par des ions zirconium (Zr). L'oxyde de vanadium est dopé par 0,1 à 10 % en moles d'ions zirconium par rapport à l'oxyde. En utilisant le matériau actif d'électrode positive pour un accumulateur au lithium, l'élution du vanadium hors de l'électrode positive est régulée, et par conséquent, la durée de vie de l'accumulateur prolongée.
(KO) 본 발명은 지르코늄(Zr) 이온이 도핑된 바나듐 산화물을 포함하는 리튬 이차전지용 양극 활물질을 제공한다. 상기 지르코늄 이온은 바나듐 산화물을 기준으로 0.1mol%이상 10mol%미만이 도핑된다. 상기 리튬 이차전지용 양극 활물질을 리튬 이차전지에 적용함으로써, 양극에서 바나듐의 용출이 억제되고, 이에 따라 전지의 수명이 향상된다.
