Regarding Claim 2, Kim anticipates the invention of Claim 1. Additionally, Kim discloses structure where the battery housing includes a beading portion formed at an end adjacent to the open portion, and press-fitted toward an inner side thereof, as shown in figure 1. Additionally, the first housing coupling portion is coupled to the beading portion through contact with the battery housing, where the battery housing comprises the beading portion. Regarding Claim 3, Kim anticipates the invention of Claim 1. Additionally, Kim discloses structure where the first housing coupling portion includes a first contact portion coupled to the inner surface of the battery housing, that being the outermost portions of the first current collector plate 40 which contacts the battery housing, and a first connection portion for connecting the support portion and the first contact portion, the first connection portion being the portion located between the support portion and first contact portion. Regarding Claim 4, Kim anticipates the invention of Claim 3. Additionally, Kim discloses structure wherein the first contact portion, which is the portion of the first housing coupling portion in direct contact with the battery housing 20, has a shape which at least a part of extends along an inner circumference of the battery housing, based on Kim’s figure 1 which depicts the placement of the connecting portion and housing, and figure 2 which shows the full shape of the current collector plate. Regarding Claim 5, Kim anticipates the invention of Claim 3. Additionally, Kim discloses structure where the first connection portion includes first bending portions in which an extension direction thereof is changed, shown in figure 1, where the extension direction of the connection portion of the current collector 40 changes. Regarding Claim 6, Kim anticipates the invention of Claim 1. Additionally, Kim discloses structure wherein the first current collecting plate further includes a second housing coupling portion extending from an end of the tab coupling portion, shown in figure 2 as the portions of the first current collecting plate which are raised compared to the lowermost portions which comprise the tab connecting portion. Based on the placement shown in figure 1, these portions which contact the housing extend from an end of the tab coupling portion and are coupled to the inner surface of the battery housing. Regarding Claim 7, Kim anticipates the invention of Claim 6. Additionally, as shown in figure 2, the second housing coupling portion includes a second contact portion coupled to the inner surface of the battery housing, this being the surface which contacts the inner surface of the battery housing, as well as a second connection portion for connecting the support portion and the second contact portion, those being inner portions of the second housing coupling portion which are in contact with the support portion and second contact portion, thereby being portions for connecting said components. Regarding Claim 8, Kim anticipates the invention of Claim 7. Additionally, where the second contact portion is coupled to the inner surface of the battery housing, as shown in figure 2, it has a shape in which at least a part thereof extends along an inner circumference of the battery housing. Regarding Claim 9, Kim anticipates the invention of Claim 7. Additionally, Kim discloses structure wherein the second connection portion includes at least one second bending portion in which an extension direction thereof is changed, as shown in figure 2, where the innermost portion of the second connection portion include a portion which extends upwards, which is a differing extension direction. Regarding Claim 10, Kim anticipates the invention of Claim 10. Additionally, Kim discloses structure wherein the sealing spacer includes a movement prevention unit interposed between the first current collecting plate and the cap plate, where the movement prevention unit is the lowermost section of the gasket 31 as shown in figure 1, which is located between the first current collecting plate 40 and the cap plate 32, being positioned such that it would prevent movement of the battery components which contact it. Additionally, the sealing spacer comprises a sealing portion interposed between the battery housing 20 and the cap plate 32, and a connection portion configured to connect the movement prevention unit and the sealing portion. Regarding Claim 11, Kim anticipates the invention of Claim 10. Additionally, Kim discloses structure where the movement prevention unit has a height corresponding to a distance between the first current collecting plate and the cap plate, where the height of the movement prevention unit is a subsection of the distance between the first current collecting plate and the cap plate, and therefore correspondence exists between the two heights. Regarding Claim 12, Kim anticipates the invention of Claim 10. Additionally, Kim discloses structure wherein the movement prevention unit is located at a center on one surface of the electrode assembly, being located above a center on a surface of the electrode regions 11a and 12a. Regarding Claim 13, Kim anticipates the invention of Claim 10. Additionally, Kim discloses structure wherein the movement prevention unit has a spacing hole formed at a position corresponding to a winding center hole of the electrode assembly, as depicted in their figure 1. Regarding Claim 14, Kim anticipates the invention of Claim 10. Additionally, Kim discloses structure where the sealing portion of the sealing spacer has a shape extending along a periphery of an inner circumference of the battery housing, as shown in figure 1.
