(KO) 리튬 이차 전지
Abstract:
(EN) The present invention relates to a lithium secondary battery. The lithium secondary battery comprises: a cathode comprising a cathode active material represented by following formula 1, a plate-like conductive agent, and a spherical conductive agent; an anode comprising an anode active material; and an electrolyte, wherein the cathode has a W value defined by following formula 1 of 1.0 to 1.5. [Formula 1] LiaNixCoyMezO2 (where 0.9 ≤ a ≤ 1.1, 0.5 ≤ x ≤ 0.90, 0.05 ≤ y ≤ 0.5, 0.01 ≤ z ≤ 0.5, x + y + z =1, and Me is Mn or Al.)
(FR) La présente invention concerne une batterie secondaire au lithium. La batterie secondaire au lithium comprend : une cathode comprenant un matériau actif de cathode représenté par la formule suivante 1, un agent conducteur de type plaque, et un agent conducteur sphérique ; une anode comprenant un matériau actif d'anode ; et un électrolyte, la cathode ayant une valeur W définie par la formule suivante 1 de 1,0 à 1,5. Formule 1 : LiaNixCoyMezO2 (où 0,9 ≤ a ≤ 1,1, 0,5 ≤ x ≤ 0,90, 0,05 ≤ y ≤ 0,5, 0,01 ≤ z ≤ 0,5, x + y + z = 1, et où Me représente Mn ou Al).
