5? spinel complex-oxide prepared, method for preparing the same, and lithium secondary batteries using the same

摘要

The present invention relates to a 5V spinel composite solid oxide and a method of manufacturing the same. More specifically, by the co-precipitation method, the formula Li _{1 + x} [Ni _y Co _z Mn _2-yz ] O _4-δ F _δ (0 ≦ x ≦ 0.2, 0 having uniform particles of about 10 μm) ≤ y ≤ 0.6, 0 ≤ z ≤ 0.2, 0 ≤ δ ≤ 0.5), excellent charge-discharge cycle characteristics and capacity storage characteristics, 5V class spinel composite solid oxide for lithium secondary batteries with improved high rate characteristics, manufacturing method And it provides a lithium secondary battery comprising the same.;The 5 Ｖ grade spinel cathode material of the present invention had excellent structural characteristics as the structural variation did not occur according to the number of charge / discharge cycles, and its discharge capacity was also excellent as 100 to 120 mAh / g.;Coprecipitation Method, Cathode Active Material, High Rate Properties, High Stability, 5V Class Spinel Oxide
