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: A vehicle communicating with a remote controller is provided. A vehicle includes a plurality of car antennas; a storage configured to store a distance value between the first and second key antennas; and a controller configured to select at least two of the plurality of car antennas, control transmission of signals through the selected at least two car antennas, obtain a distance value between the first and second key antennas of the remote controller based on the received signal strength and the transmission strength of the at least two car antennas when a received signal strength of at least two signals received by the first key antenna and a received signal strength value of at least two signals received by the second key antenna are received from the remote controller, and authenticate the remote controller based on the obtained distance value and the distance value stored in the storage.

Abstract: A vehicle may include: a conductive coil; and an authenticator configured to be turned on in response to receiving a current and to request an encryption key from a remote control apparatus. An induction current may be induced in the coil when a magnetic body approaches the coil, and the authenticator may be further configured to be activated in response to receiving the induction current from the coil.
