Lithium Polymer Battery tabs

Lithium Polymer Battery tabs are the original material for lithium-ion polymer battery products.

The positive electrode uses aluminum (Al) material,
The negative electrode uses nickel (Ni) or nickel-plated copper (NICU) material.

The electrode is made of film and metal strips,
The insulating part film on the tab prevents a short circuit between the aluminum-plastic film and metal strip when the Lithium Polymer Battery is made and heats (about 140°C) the aluminum-plastic film to avoid the short circuit from occurring leakage.

The Lithium Polymer Battery tab is made of two pieces of film (ordinarily black, white, and single-layer), sandwiching the metal strip in the middle.

The vinyl film has a three-layer structure:
PE: melting point of 66°C
PP: melting point of 105°C
Melanin: melting point of 66°C

The Lithium Polymer Battery tab connects, conducts, and seals for connecting the battery;
The Lithium Polymer Battery tab combines tab glue and aluminum-plastic film, electricity comes out through the Lithium Polymer Battery tabs, and the circuit appears;

Sealing refers:
rubber strip and the metal belt film seal
the rubber strip and the aluminum-plastic film seal

We can provide a custom solution for you,
the width and length of the tabs for ultra-thin Lithium Polymer Batteries can adjust as the customer requests, and the protection circuit, wires, and connectors of the battery also can be changed.
