The Electrodes For Secondary Battery and the Secondary Battery Comprising the Same

摘要

Disclosed is an electrode for secondary batteries including an electrode mixture including an electrode active material, binder and conductive material coated on a current collector. The present invention provides an electrode for secondary batteries wherein an electrode active material is a cathode active material and/or anode active material, a cathode active material includes an oxide represented by Formula 1 below, an anode active material includes an oxide represented by Formula 2 below and the conductive material is included in an amount of 0.1 to 15% based on total weight of the electrode mixture, and a secondary battery including the same:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒLi x M y Mn 2-y O 4-z A z €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein 0.9‰¤x‰¤1.2, 0M is at least one element selected from the group consisting of Al, Mg, Ni, Co, Fe, Cr, V, Ti, Cu, B, Ca, Zn, Zr, Nb, Mo, Sr, Sb, W, Ti and Bi; and
A is at least one monovalent or divalent anion,
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒLi a M' b O 4-c A c €ƒ€ƒ€ƒ€ƒ€ƒ(2)
wherein M' is at least one element selected from the group consisting ofTi, Sn, Cu, Pb, Sb, Zn, Fe, In, Al and Zr; 0.1‰¤a‰¤4 and 0.2‰¤b‰¤4 in which a and b are determined according to oxidation number of M'; 0‰¤c‰¤0.2 in which c is determined according to oxidation number of A; and A is at least one monovalent or divalent anion.
