Copper & Nickel Strip for Battery Tabs, a raw material for lithium-ion polymer battery products. There are three types of Copper & Nickel Strip for Battery Tabs materials: aluminum (Al) for the positive electrode, nickel (Ni) for the negative electrode, and nickel-plated copper (Ni-Cu) for the negative electrode, all of which are made by laminating two parts: a film and a metal strip.
The film is the insulating part of Copper & Nickel Strip for Battery Tabs, and its function is to prevent short circuit between the metal strip and the aluminum-plastic film when the battery is encapsulated, and to prevent leakage by heating (about 140°C) and sealing with the aluminum-plastic film by heat fusion.
A Copper & Nickel Strip for Battery Tabs is made of two films that sandwich the metal strip in between. There are three types of films used in the market: black film, white film and single-layer film. The commonly used black film is a three-layer structure: melanin, which has a melting point of 66°C; PE, which has a melting point of 105°C; and PP, which has a melting point of 137°C. The finished packaging of Copper & Nickel Strip for Battery Tabs is divided into tray type (the entire metal strip is wrapped around into a tray by adding film to the equipment) and plate type (the metal strip is added to the film and cut into individual pieces, then lined up in a row with (sandwiched between two thin transparent plastic sheets).
The “pole” refers to the “pole” in “positive” and “negative”, while the “ear” refers to the adhesive strip used in “positive” and “negative”, which is symmetrical like human “ears” on both sides of the metal strip, a combination of function and image. Taiwan calls “Copper & Nickel Strip for Battery Tabs” as “Guide Handle” and similar to this name, the industry commonly used is “shoulder height” and “shoulder width”. It can be regarded as a continuation or subdivision of the name “Copper & Nickel Strip for Battery Tabs”, because the height and width of “ear” is difficult to measure, while “shoulder” can, so later “shoulder height” and “shoulder width” were not named as “ear height” and “ear width”.
To be more precise, “Copper & Nickel Strip for Battery Tabs” is “Connection, Conductor, Seal”. Among them, “connection” refers to the connection between the inside and outside of the battery, and the connection between the rubber tab and the aluminum plastic film; “conductive” refers to the electrical circuit formed by drawing electricity through the tab; “seal” refers to the seal between the rubber strip and the metal strip, and the seal between the rubber strip and the aluminum plastic film. And “sealing” refers to the sealing between the rubber strip and the metal strip and the sealing between the rubber strip and the aluminum plastic film.
