Abstract: Disclosed is a cathode active material for secondary batteries comprising at least one compound selected from the following formula 1: (1?s?t)[Li(LiaMn(1-a-x-y)NixCoy)O2]*s[Li2CO3]*t[LiOH] (1) wherein 0<a<0.2, 0<x<0.9, 0<y<0.5, a+x+y<1, 0<s<0.03, and 0<t<0.03; and a, x and y represent a molar ratio, and a and t represent a weight ratio. The cathode active material has long lifespan at room temperature and high temperatures and provides superior stability, although charge and discharge are repeated at a high current.

Abstract: Provided is a cathode active material which is lithium transition metal oxide having an ?-NaFeO2 layered crystal structure, wherein the transition metal is a blend of Ni and Mn, an average oxidation number of the transition metals except lithium is +3 or higher, and lithium transition metal oxide satisfies the Equation m(Ni)?m(Mn) (in which m (Ni) and m (Mn) represent an molar number of manganese and nickel, respectively). The lithium transition metal oxide has a uniform and stable layered structure through control of oxidation number of transition metals to a level higher than +3, thus advantageously exerting improved overall electrochemical properties including electric capacity, in particular, superior high-rate charge/discharge characteristics.

Abstract: Disclosed are a method of manufacturing multilayer ceramic electronic components and a multilayer ceramic electronic component using the same. There is provided a method of preparing a plurality of ceramic layers including a first side, a second side, a third side, and a fourth side; printing a first inner electrode pattern and a second inner electrode pattern on the ceramic layers, the first inner electrode pattern and the second inner electrode pattern being exposed to the first side or the third side and having concave portions in the second side and fourth side directions; and stacking and compressing the plurality of ceramic layers printed with the first inner electrode pattern and the second inner electrode pattern.

Abstract: There is provided a multilayer ceramic capacitor. The multilayer ceramic capacitor includes an effective layer including inner electrodes and dielectric layers that are alternately stacked, and a protection layer formed on each of top and bottom surfaces of the effective layer, the protection layer being formed by stacking dielectric layers. The effective layer has an outside part, an inside part and an outside part in that order along a stack direction, the inner electrodes of the outside parts have a smaller thickness than that of the inner electrodes of the inside part, and the outside parts have a thickness 0.1 to 0.5 times that of the protection layer.
