摘要： An electrode assembly and a secondary battery including the same. The electrode assembly includes: a positive electrode plate including a positive electrode active material applied to a positive electrode collector; a negative electrode plate including a negative electrode active material applied to a negative electrode collector; a separator disposed between the positive electrode plate and the negative electrode plate; and a ceramic layer disposed on a portion of the positive or negative electrode plate, adjacent to an outer surface of the electrode assembly. The positive electrode plate, the negative electrode plate, ceramic layer, and the separator are wound together. The ceramic layer prevents a short-circuit between the positive electrode plate and the negative electrode plate, and extends along between about 40% and 90% of the length of the positive or negative electrode plate, from a winding end thereof.

摘要： Provided is a lithium secondary battery which is stable to penetration of a sharp object, which may occur by external impact. The lithium secondary battery comprises an electrode assembly which is formed by winding a first electrode plate, a second electrode plate, and a separator disposed between the first electrode plate and the second electrode plate; and a can for receiving the electrode assembly, wherein the separator is formed of a ceramic material, a polarity of the first electrode plate is opposite to that of the can, and the outermost part of the first electrode plate is disposed further outside than the outermost part of the second electrode plate.
