Abstract: A secondary battery includes: an electrode assembly; a case body accommodating the electrode assembly; a cap plate sealing an opening of the case body; and a positive electrode terminal and a negative electrode terminal, each of the positive electrode terminal and the negative electrode terminal being electrically connected to the electrode assembly, coupled to the cap plate, and protruding in a first direction from an upper surface of the cap plate. The cap plate includes a vent portion located between the positive electrode terminal and the negative electrode terminal. A first length of the case body in the first direction is longer than a second length of the case body in a second direction perpendicular to the first direction, and the second length is longer than a third length of the case body in a third direction perpendicular to each of the first direction and the second direction.

Abstract: The present disclosure relates to an electrode assembly and a method of manufacturing the electrode assembly. The electrode assembly may include an electrode assembly including a positive electrode plate including a non-coated portion having a first side in a first direction and a first composite portion disposed adjacent to the non-coated portion in a first direction. The positive electrode plate may also include a positive electrode groove portion at a vertex where the first side and a second side meet. The electrode assembly may also include a negative electrode plate including a second composite portion covering a surface of the first composite portion and a negative electrode groove portion at a vertex where a third side and a fourth side of the negative electrode plate meet. A separator may be disposed between the positive electrode plate and the negative electrode plate.

Abstract: A cap assembly includes a cap plate that is coupled to a case, the case having an open upper end, the cap plate including a first vent hole, a first terminal and a second terminal electrically connected to an electrode assembly accommodated in the case and protruding from an upper surface of the cap plate, and an insulating plate below the cap plate, the insulating plate including a second vent hole positioned to correspond to the first vent hole, wherein each of the cap plate and the insulating plate includes terminal through-holes through which the first terminal and the second terminal are connected to electrode plate tabs on the electrode assembly.

Abstract: The present disclosure relates to a cleaner station including a suction flow path having an inlet end configured to communicate with a dust bin of a cleaner, a dust collecting part connected to an outlet end of the suction flow path and configured to capture dust in the dust bin of the cleaner, and a spray module disposed at one side of the dust collecting part and configured to spray at least any one of the sterilization gas and particulates into the dust collecting part to kill insects existing in the dust collecting part, in which the spray module sprays the sterilization gas, which contains ozone or ion particles, into the dust collecting part, to kill insects existing in the dust collecting part.

Abstract: The present disclosure relates to a cleaner, and a cleaner according to an embodiment of the present disclosure includes a main body, and a cleaning nozzle separably connected to the main body, in which the main body includes a battery configured to supply power, an operating part including at least one input button, and a main body control unit configured to receive a user input for manipulating the input button and transmit a control instruction to the cleaning nozzle when the cleaning nozzle is connected to the main body, and in which the cleaning nozzle includes a nozzle control unit configured to receive the control instruction through a power line connected to the main body control unit, and at least one operation part configured such that an operation of the operation part related to a function of the cleaning nozzle is controlled by the nozzle control unit.
