Provide battery tabs such as aluminum, copper and nickel Tabs

Xiaowei provide battery tabs in aluminum, copper and nickel, as well as machinery and battery materials for lithium battery manufacturers

Battery tabs are an important part of lithium battery production used to connect the cathode and anode terminals of the battery and lead the current, the complete battery tabs are mainly composed of insulating sealant and metal conductive. For lithium ion batteries, aluminum lugs are used for the cathode tab and pure nickel strip lugs or nickel-plated copper strip lugs are used for the anode tab.

Providing different materials for battery tabs

Depending on the type of lithium battery you are producing, Xiaowei can provide battery tabs made of different materials to meet your production needs. The following are the types of battery tabs we often offer:

(1) Aluminum tabs: These are aluminum-made tabs that are often as the positive electrode material used for the Li-ion battery. Aluminum is perfect for these terminals not only because, compared to other materials, the terminal density, and, therefore, battery weight is low. Also, aluminum’s electrical conductivity is very good, and it has corrosion resistance.

(2) Nickel tabs: These are the negative electrodes which are utmost in the lithium-ion batteries, particularly in the small digital batteries starting from the elementary cell phone batteries, the mobile power batteries as well as the tablet PC batteries.

(3) Copper nickel plated materials: However, the copper nickel plated material might be one such compound that is used as anode lugs in high rate batteries like the electric vehicle batteries and the solid-state batteries. The good electrical conductivity of copper is combined with nickel’s property of being corrosion resistant through the copper nickel plating. As a result, the plating exhibits superior resistance to high-performing batteries.

(4) Silver Material: In some specialized applications, silver as a material may be found on the lugs in these places, but is not usually present in many battery products because it is quite expensive.

We will test the battery tabs upon completion of production and before shipment to ensure that the connection of your battery is safe and the circuit is reliable.

In addition to the battery tabs, we also provide insulating sealing tapes

In addition to the metal strip, the battery tabs also include insulating films, which are used to prevent short circuits between the metal strip and the aluminum-plastic film during battery packaging, and to heat and seal with the aluminum-plastic film during the packaging process to prevent leakage. Commonly used films include black glue, white glue, and single-layer glue, which have different melting points and performance characteristics. Black glue tabs are usually used on low-end digital small lithium batteries, yellow glue tabs are generally used on low-end power batteries and high-rate batteries, and white glue is generally used on high-end digital batteries, power batteries, and high-performance batteries. Overall, white glue has the best insulation performance and safety.


The battery tabs are metal conductors that lead the positive and negative electrodes out of the battery cell. In layman’s terms, the tabs on the positive and negative poles of the battery are the contact points during charging and discharging. They are composed of two parts: film and metal strip.

Battery foil is an important raw material for lithium battery production. Aluminum foil is used in lithium battery positive electrode current collectors, lithium battery outer packaging aluminum plastic film and battery tabs. In addition, batteries also use copper foil, nickel foil and other metal materials.

During the battery cell production process, the battery tabs can demonstrate good conductivity and connectivity. The tabs produced through special processing have strong corrosion resistance, stable conductivity, high energy density, high power density, and long cycle life.

Xiaowei mainly uses ultrasonic welding technology to manufacture battery tabs. This manufacturing process is conducive to improving the qualified inspection rate of battery tabs and meeting the needs of mass production. We also provide the equipment required for battery tab manufacturing. You are welcome to contact us at any time!

It is widely used in industries such as consumer soft-pack lithium-ion batteries, high-rate lithium-ion batteries, and power lithium-ion batteries. Its market application has expanded from consumer batteries to medical devices, power tools, electric bicycles, electric vehicles, energy storage, etc.

At a time when the high rate performance of battery cells is emphasized, the battery tab structure is increasingly valued by large battery manufacturers. Especially for electric vehicle batteries, as the foil becomes thinner and the number of tab layers increases, the battery tab welding process itself becomes more and more difficult!
