What is a pole ear?

In simple terms, the pole ear is a component of soft pack lithium battery products used in 3C consumer products and electric vehicles, which is divided into positive electrode (aluminum material) and negative electrode (nickel or copper nickel-plated material), which is heated by two parts of the metal strip and film. In the process of participating in the cell production, the pole ear can play a good electrolyte resistance, HF resistance, and aluminum-plastic film bonding performance, after special process production of the pole ear corrosion resistance, leak proof, stable conductive performance, high energy density, high power density, long cycle life, green environmental protection.
