  • Publication number: 20240154252
    Abstract: A secondary battery includes a cylindrical case; an electrode assembly accommodated in the case and including a first electrode plate, a second electrode plate, and a separator, the electrode assembly being wound such that the first electrode plate is arranged at an outermost side and is in contact with the case; a cap assembly coupled to the case and electrically connected to the second electrode plate; and a first swelling tape attached to an inner surface of the first electrode plate in a state in which the electrode assembly is wound, the first swelling tape having a multi-layer structure. The swelling tape may be applied to a base material finishing portion of the electrode assembly to improve quality distribution of the base material finishing structure due to long-diameter distribution. In addition, a swelling effect may be improved through the multi-layer swelling tape.

  • Publication number: 20240136674
    Abstract: Disclosed is an electrode assembly, a battery, and a battery pack and a vehicle including the same. In the electrode assembly, a first electrode, a second electrode, and a separator interposed therebetween are wound based on a winding axis to define a core and an outer circumference. The first electrode includes a first active material portion coated with an active material layer and a first uncoated portion not coated with an active material layer along a winding direction. At least a part of the first uncoated portion is defined as an electrode tab by itself. The first uncoated portion includes a first portion adjacent to the core of the electrode assembly, a second portion adjacent to the outer circumference of the electrode assembly, and a third portion interposed between the first portion and the second portion. The first portion or the second portion has a smaller height than the third portion in the winding axis direction.

  • Publication number: 20240128517
    Abstract: Disclosed is an electrode assembly, a battery, and a battery pack and a vehicle including the same. In the electrode assembly, a first electrode, a second electrode, and a separator interposed therebetween are wound based on an axis to define a core and an outer circumference. The first electrode includes an uncoated portion at a long side end thereof and exposed out of the separator along a winding axis direction of the electrode assembly. A part of the uncoated portion is bent in a radial direction of the electrode assembly to form a bending surface region that includes overlapping layers of the uncoated portion, and in a partial region of the bending surface region, the number of stacked layers of the uncoated portion is 10 or more in the winding axis direction of the electrode assembly.

  • Patent number: 11935997
    Abstract: Disclosed are a pouch exterior capable of easily mounting an electrode assembly at an accurate position between accommodating parts, having an integrated form to minimize sealing parts contacting the air and to increase a lifetime of a battery, capable of preventing a rupture of the pouch exterior in an assembly process, and capable of increasing an energy density of a cell, a pouch-type secondary battery using the pouch exterior, and a method of manufacturing the pouch-type secondary battery. A pouch exterior for a secondary battery, according to the present disclosure, includes two corresponding accommodating parts configured to mount an electrode assembly therebetween and symmetrically formed at both sides by disposing a protruding part therebetween, and is folded along two folding lines outside a center pan of the protruding part by vertically mounting a side surface of the electrode assembly on the protruding part, such that folded parts surround side edges of the electrode assembly.

  • Publication number: 20100193491
    Abstract: A substrate support unit of a substrate processing apparatus includes a first support member, a second support member, a buffer member and a tube. The first support member has an electrode and a heater built-in and supports the substrate. The second support member is disposed beneath the first support member to support the first support member. The buffer member is disposed between the first support member and the second support member to form an air gap between the first support member and the second support member so as to reduce heat transfer between the first support member and the second support member. The tube is connected with a lower surface of the first support member. Further, the tube extends through the second support member and receives lines for applying power to the electrode and the heater.

  • Publication number: 20100104403
    Abstract: An apparatus for transferring a wafer includes a ceramic blade, an electrode, a plurality of pads, a coating layer and a robot arm. The blade supports the wafer, and the electrode is disposed inside the blade. Electric power is applied to the electrode to generate an electrostatic force for holding the wafer. The pads are disposed on an upper surface of the blade, and thus frictional forces may be provided between the wafer and the pads. The coating layer is disposed on the blade. The robot arm is connected with the blade to move the blade.
