Abstract: A lithium secondary battery may include a battery can, an electrode assembly and an electrolyte received in the battery can, and a cap plate to seal the battery can. The battery can includes a first end portion and a second end portion opposite the first end portion. The lithium secondary battery is configured so at least a portion of the electrode assembly is ejected through the first end portion of the battery can when an internal pressure within the battery can is 21 kgf/cm2 or more. After the portion of the electrode assembly is ejected through the first end portion, a distance from an end portion of the electrode assembly located farthest away from the battery can to the second end portion of the battery can is greater than or equal to 1.25 times a distance between the first end portion and the second end portion of the battery can.

Abstract: The present disclosure relates to a battery including a battery can, an electrode assembly and an electrolyte received in the battery can, and a cap plate assembly to seal the battery can, a battery pack and a vehicle including the same. The battery can has a first end and a second end opposite to each other. When the electrode assembly is ejected through the first end of the battery can by an internal pressure, a distance from the end of the electrode assembly farthest away from the battery can to the second end of the battery can is 1.25 times or more as much as a distance between the first end portion and the second end portion of the battery can; and the ejected portion of the electrode assembly has a mass that is at least 25% of the total mass of the electrode assembly before the ejection.

Abstract: The present invention relates to a secondary battery including: an electrode assembly; a case opened on one side and configured to accommodate the electrode assembly therein; a vent coupled to the opening of the case; and a first current collecting plate electrically connected to the electrode assembly, in which the first current collecting plate is welded and electrically connected to at least one of the case and the vent.

Abstract: A mobile terminal and controlling method thereof are disclosed, by which a water mode can be automatically entered in a manner of periodically monitoring a capacitance value of a touchscreen. The present invention includes an electrostatic touchscreen and a controller, if at least one of a size of a capacitance value detected through the touchscreen and a variation of a per-region capacitance value detected through the touchscreen meets a first condition, entering a water mode for disabling a touch control function of the touchscreen.
