摘要： Disclosed is a battery casing, comprising one or more sub-layers as constitutional elements, wherein at least one region selected from the group consisting of a surface of the casing and the sub-layers of the casing is coated partially or totally with a metal having a grain size of 50 nm or less. A battery comprising the same casing is also disclosed. The casing efficiently inhibits degradation of the safety of a battery, caused by internal or external factors, and thus provides a battery with excellent safety.

摘要： In a battery in which a separator is disposed between a cathode and an anode, a jelly roll is wound with the separator. The cathode, the anode and the separator are received in a battery case and surrounded with an electrolyte, and an opening of the battery case is sealed by a top cap assembly connected to the cathode. A curved groove is formed on the battery case as a safety element for preventing the explosion of the battery due to an increase of internal pressure, the groove being formed along a line of equal stress on the surface of the battery case.
