Battery Tabs for Lithium-Ion Batteries

Datum is a leading supplier of high-quality battery tabs for lithium-ion battery pack manufacturers, supplying custom battery pack connectors.

What is a Battery Tab?

Battery tabs are essential components in battery pack assembly, acting as the conductive pathways that connect the battery’s internal cells to its external circuitry. These tabs are typically made from highly conductive metals such as copper, aluminium, nickel or nickel plated steel, and their primary role is to ensure efficient and reliable electrical connectivity. The battery tab must handle the high currents flowing in and out of the battery while maintaining mechanical integrity over the battery’s life cycle. They are crucial in maintaining the battery’s performance, safety, and longevity.

What are Lithium-Ion Batteries Used For?

Lithium-ion batteries (Li-ion batteries) are ubiquitous in modern technology due to their high energy density, long cycle life, and relatively low self-discharge rate. They power a vast range of devices and systems across various industries, including:
1. Consumer Electronics: Li-ion batteries are found in smartphones, laptops, tablets, cameras, and other portable electronic devices, providing the necessary power in a compact and lightweight form.
2. Electric Vehicles (EVs): The automotive industry heavily relies on Li-ion batteries to power electric vehicles. Their high energy density allows for longer driving ranges, and advancements in battery technology are continuously extending these ranges.
3. Renewable Energy Storage: Li-ion batteries are used in solar and wind energy storage systems. They store excess energy generated during peak production times and release it during periods of high demand or low production, thus stabilizing the energy supply.
4. Medical Devices: Many medical devices, such as portable defibrillators, infusion pumps, and hearing aids, utilise Li-ion batteries due to their reliability and long operational times.
5. Power Tools: Cordless power tools, including drills, saws, and garden equipment, benefit from the high-power output and durability of Li-ion batteries.
6. Aerospace and Defence: These batteries are used in satellites, drones, and various defence applications, where weight and energy efficiency are critical.

Properties Required for Battery Tabs

The performance and safety of lithium-ion battery packs are highly dependent on the quality and properties of the battery tabs. Key properties required for battery tabs include:
1. High Electrical Conductivity: To ensure efficient energy transfer, battery tabs must have high electrical conductivity. This minimises energy loss and heat generation during charging and discharging cycles. Copper, nickel, stainless steel and aluminium are commonly used materials due to their excellent conductive properties.
2. Thermal Stability: Battery tabs must withstand high temperatures without degrading or losing their mechanical properties. Thermal stability is critical to prevent overheating and potential thermal runaway, which can lead to battery failure or even fires.
3. Mechanical Strength: Battery tabs must maintain their structural integrity during assembly, usage, and over the battery’s lifecycle. They need to endure physical stress, vibrations, and possible impact without breaking or deforming.
4. Corrosion Resistance: Since batteries operate in various environments and conditions, battery tabs must resist corrosion. This ensures long-term reliability and prevents performance degradation due to environmental factors.
5. Ease of Welding: The ability to weld battery tabs effectively is crucial for manufacturing efficiency. Tabs should allow for secure and reliable welding connections to the battery cells, ensuring robust electrical and mechanical contact.
