POSITIVE ELECTRODE ACTIVE MATERIAL AND LITHIUM SECONDARY BATTERY USING SAME |
| 摘要 |
The present invention relates to a positive electrode active material for a secondary battery, comprising the combination of one or more compounds selected from the following chemical formula 1, one or more compounds selected from the following chemical formula 2, and one or more compounds selected from the following chemical formula 3: (1-s-t)[Li(LiaMn(1-a-x-y)NixCoy)O2]*s[Li2CO3]*t[LiOH] (1); Li(LibMn(2-b))O4 (2); and (1-u)LiFePO4*uC (3), wherein 0<a<0.3, 0<x<0.8, 0<y<0.6, 0<s<0.05, 0<t<0.05, 0<b<0.3, and 0.01<u<0.1, a, b, x and y denote mole ratios, and s, t and u denote weight ratios. The above-described positive electrode active material enables a high-power lithium secondary battery comprising a non-aqueous electrolyte, which has a long lifespan and good storage properties at room temperature and at a high temperature, and which exhibits superior safety, rate characteristics, and power characteristics, to be provided. |
