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.

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.

Abstract: A wet shaving razor is provided with a first support formed on a handle and including a guiding groove formed at a middle portion of an upper surface thereof, and a pair of spring grooves formed on both lateral sides of the guiding groove, respectively, each of the spring grooves having a stepped portion, first springs being mounted within the spring grooves, respectively, a movable member movably mounted in the first support and including lateral wings inserted into the spring grooves, respectively, and an abutment member resiliently supported with respect to the movable member by a second spring and a blade receiving plate on which the blade assembly is mounted, a center lower end of the blade receiving plate hinged at the movable member, the blade receiving plate including an engaging hole at its rear surface into which the abutment member is engaged.
