Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0025] figure 1 is an exploded perspective view of a core pack 200 of a secondary battery according to an embodiment of the present invention, figure 2 is shown assembled figure 1 A perspective view of the state of the core pack 200 is shown.

[0026] refer to figure 1 with figure 2 , the core pack 200 includes a bare cell 110 , a protection circuit module 120 and an upper case 130 .

[0027] The bare cell 110 includes an electrode assembly (not shown), an electrode terminal 111 and a first insulating tape 112 . In the illustrated embodiment, the bare cell 110 is a pouch type bare cell. The electrode assembly includes a positive electrode plate, a separator, and a negative electrode plate stacked in sequence, and is wound in a jelly-roll configuration, and then accommodated inside the bare cell 110 .

[0028] The electrode terminal 111 in...

Abstract

The invention provides a method of packaging a secondary battery and a forming device for packaging the secondary battery.The method comprises the following steps of arranging a bare cell wound with a label on the forming device, heating the label to integrate it with the bare cell, providing the bare cell with molten resin obtained from the forming device.The molten resin is solidified when contacting with the label, thereby forming the lower housing.

Description

technical field [0001] Aspects of the present invention relate to a method of packaging a secondary battery and a molding apparatus suitable for packaging the secondary battery. Background technique [0002] Recently, lithium ion secondary batteries have become widely used because they provide high nominal voltage per cell and high energy density per unit weight / volume. [0003] In a lithium ion secondary battery, lithium oxide is generally used as an active material of a positive plate, and a carbon material is generally used as an active material of a negative plate. Lithium-ion secondary batteries can use non-aqueous liquid electrolytes or solid polymer electrolytes containing organic solvents. In particular, lithium ion secondary batteries employing solid polymer electrolytes can be classified as lithium ion polymer batteries. Lithium ion secondary batteries can also be classified into cylindrical type batteries, prismatic type batteries, pouch type batteries, etc. acc...
