Nickel tabs are mainly used for the negative electrode. Nickel tabs are typically used as the negative electrode tabs for lithium-ion batteries, primarily applied in small digital batteries such as mobile phone batteries, power bank batteries, tablet batteries, etc.
The main material for nickel tabs is nickel (Ni), which is composed of a film and a metal strip. In batteries, nickel tabs serve the functions of connection, conduction, and sealing. They can effectively draw out current, form a circuit, and have good electrolyte resistance and HF resistance.
In addition, the surface treatment of nickel tabs usually includes nickel plating and chemical nickel plating processes to enhance their conductivity and corrosion resistance.
