Definitions
- the present invention relates to a sealing device and a sealing method for a pouch-type battery case. Specifically, the present invention relates to a sealing device and a sealing method for a pouch-type battery case including a support die and a non-contact heating member for heating a sealing portion of the pouch-type battery case.
- Lithium secondary batteries are classified into pouch-type secondary batteries composed of laminated sheets, cylindrical secondary batteries composed of metal materials, and square secondary batteries, depending on the type of outer packaging material. Pouch-type secondary batteries have the advantages of being easy to change shape, easy to manufacture, and having low manufacturing costs.
- a pouch-type secondary battery comprises an electrode assembly including a cathode, an anode, and a separator arranged between the cathode and the anode, housed inside a pouch-type battery case made of a laminated sheet.
- a cathode lead and an anode lead are connected to each of the cathode tabs and the anode tabs constituting the cathode and the anode, and then extended so as to be exposed to the outside of the pouch-type battery case.
- the pouch-type battery case is composed of a first case and a second case that accommodate an electrode assembly inside, and the first case and the second case are made of a laminate structure including an outer resin layer that protects the electrode assembly from the outside, a metal layer for blocking air and moisture, and an inner resin layer for heat-sealing.
- the first case and the second case are arranged so that their respective internal resin layers face each other, and the positive and negative leads are arranged so that they penetrate the outer periphery of the first case and the second case, and the outer periphery is heat-welded to form a sealing portion.
- a lead film may be attached to the upper and lower surfaces of each of the positive and negative electrode leads.
- Figure 1 is a front view illustrating the process of sealing a conventional pouch-type battery case.
- a pouch-type battery cell accommodates an electrode assembly (20) inside a battery case (10), and the battery case (10) includes a first case (11) that accommodates the electrode assembly (20), and a second case (12) that is arranged on an upper surface of the first case (11) and thermally fused with the first case (11).
- the first case (11) and the second case (12) are composed of laminate sheets including an outer resin layer that protects the electrode assembly (20) from the outside, a metal layer for blocking air and moisture, and an inner resin layer for heat-sealing.
- the positive lead (21) combined with the positive tab of the electrode assembly (20) protrudes outward by penetrating the outer periphery of the battery case (10) while having a lead film (23) attached to the upper and lower surfaces.
- the outer periphery of the battery case (10) is placed between a pair of sealing tools (30) consisting of a first sealing tool (31) and a second sealing tool (32). Then, when the outer periphery of the battery case (10) is pressed by the first sealing tool (31) and the second sealing tool (32) heated to a certain temperature, the inner resin layers of the first case (11) and the second case (12) are melted and thermally fused to each other to form a sealing portion.
- a first recessed portion (31a) may be formed in the first sealing tool (31) and a second recessed portion (32a) may be formed in the second sealing tool (32) to correspond to the thickness of the positive lead (21) and the lead film (23).
- the step of the first recessed portion (31a) and the step of the second recessed portion (32a) do not exactly match the thickness of the positive lead (21) and the lead film (23), the first case (11) and the second case (12) may not be securely attached, resulting in a gap, and the electrolyte may leak through this gap.
- patent document 1 discloses a process of forming a sealing portion by irradiating infrared rays to the outer surface of the electrode assembly receiving portion, which is the area to be sealed.
