A battery and battery package is disclosed which improves a battery's heat dissipation capability by using an aluminum material and a phase change material capable of maintaining a suitable temperature through phase change according to a temperature in order to prevent a battery from being deteriorated in terms of performance. More specifically, battery package has a top case and a bottom case as a battery cell case for housing a battery cell. The top and bottom cases are adhered to each other, and either or both the top and bottom cases includes: a top sheet plate repeatedly undulated at predetermined intervals to form a plurality of unidirectionally extended convex parts to be filled with a phase change material; a bottom sheet plate formed in a flat shape and adhered to the top sheet plate; and a phase change material filled in between the convex parts and the bottom sheet plate.

A battery having a battery cell, and a top case and a bottom case adhered to each other to house the battery cell, wherein the top case comprises: a top sheet plate repeatedly undulated at predetermined intervals to form a plurality of unidirectionally extended convex parts;a bottom sheet plate formed in a flat shape and adhered to the top sheet plate;enclosed phase change material filling parts disposed in a gap between the convex parts and the bottom sheet plate; anda phase change material filled in the phase change material filling part,wherein at least one end of each of the convex parts is formed with a phase change material introduction needle aperture for introducing the phase change material into the enclosed phase change material filling parts,wherein the bottom sheet plate has a same size as the top sheet plate, andwherein a wider marginal area which remains on the bottom sheet plate is adhered to the top sheet plate while wrapping the side areas of the battery cell, to enclose the battery cell. 9. The battery of claim 8, wherein the bottom case comprises: a top sheet plate repeatedly undulated at predetermined intervals to form a plurality of unidirectionally extended convex parts to be filled with a phase change material;a bottom sheet plate formed in a flat shape and adhered to the top sheet plate; anda phase change material filled in between the convex parts and the bottom sheet plate. 10. The battery of claim 8, wherein the phase change material is mixed with a filler material having a high thermal conductivity. 11. The battery of claim 8, wherein a top surface of the top sheet plate and a bottom surface of the bottom sheet plate is coated with a thermoplastic resin. 12. The battery of claim 8, wherein each of the top and bottom sheets is made up of an aluminum material. 13. The battery of claim 8, wherein the phase change material is n-octadecane. 14. The battery of claim 10, wherein the filler material is one selected from metal-based, carbon-based and ceramic-based materials and a combination thereof. 15. The battery of claim 11, wherein the thermoplastic resin is one selected from a group consisting of nylon, polyethylene and vinyl resins and a combination thereof. 16. The battery of claim 9, wherein the phase change material is mixed with a filler material having a high thermal conductivity. 17. The battery of claim 9, wherein a top surface of the top sheet plate and a bottom surface of the bottom sheet plate is coated with a thermoplastic resin. 18. The battery of claim 9, wherein each of the top and bottom sheets is made up of an aluminum material. 19. A battery package comprising: a top case and a bottom case as a battery cell case for housing a battery cell, the top and bottom cases being adhered to each other, wherein at least one of the top and bottom cases include:a top sheet plate repeatedly undulated at predetermined intervals to form a plurality of unidirectionally extended convex parts to be filled with a phase change material;a bottom sheet plate formed in a flat shape and adhered to the top sheet plate;enclosed phase change material filling parts disposed in a gap between the convex parts and the bottom sheet plate; anda phase change material filled in the phase change material filling parts,wherein at least one end of each of the convex parts is formed with a phase change material introduction needle aperture for introducing the phase change material into the enclosed phase change material filling parts,wherein the bottom sheet plate has a same size as the top sheet plate, andwherein a wider marginal area which remains on the bottom sheet plate is adhered to the top sheet plate while wrapping the side areas of the battery cell, to enclose the battery cell.
