Nickel-contained metal oxide for cathode active materials of lithium secondary batteries with enhanced properties and cathodes of lithium secondary batteries containing the same

摘要

The present invention relates to a nickel-based metal oxide which can provide a miniaturized lithium secondary battery having a capacity per mass of an active material unit mass when using a nickel-based metal oxide as an electrode material of a lithium secondary battery, Lt; / RTI In the present invention, the nickel-based metal oxide powder is analyzed by X-ray diffractometry to obtain an intensity ratio I ₀₀₃ / I ₁₀₄ between the peaks and used as means for providing improved battery characteristics. That is, by controlling the value of I ₀₀₃ / I ₁₀₄ in the active material powder within a certain range, it is possible to provide a nickel-based metal oxide capable of achieving high capacity characteristics of the battery and miniaturization of the battery.
