Product Introduction Overview
The Low Resistance Nickel Plated Steel Strip is manufactured using advanced electro-nickel plating technology on a high-quality low-carbon steel substrate. This results in a material that combines the best properties of both nickel and steel: the nickel layer provides outstanding surface conductivity, oxidation resistance, and weldability, while the steel core delivers superior tensile strength and structural rigidity at a significantly lower cost compared to pure nickel.
Engineered for modern battery applications, this strip minimizes voltage drop and heat generation during high-current discharge, making it an excellent choice for NiMH and lithium battery interconnects (tabs/busbars). It is widely used in battery pack assembly where a balance of performance, reliability, and economy is required. Available in various thicknesses and widths to meet different current-carrying needs.
Product Features
- Low Electrical Resistance — Optimized nickel plating reduces resistivity for efficient current flow and less heat buildup compared to standard plated strips.

Product FAQ
Q1: What is the difference between this low resistance nickel plated steel strip and pure nickel strip?
A: This nickel plated steel strip offers a cost-effective balance with good conductivity and much higher mechanical strength than pure nickel. While pure nickel has slightly lower resistance for ultra-high-drain applications, our optimized low-resistance version minimizes the gap while providing better rigidity and lower overall cost.
Q2: Is this strip suitable for high-current lithium battery packs?
A: Yes. It is specifically designed for low resistance and is suitable for most lithium and NiMH battery interconnects in power tools, EVs, and energy storage. For extreme high-drain scenarios, we recommend evaluating thickness and consulting current-carrying calculations.
Q3: Does the nickel plating prevent corrosion?
A: Yes. The high-quality nickel layer provides excellent protection against oxidation and corrosion, ensuring long service life even in humid or demanding environments.
Q4: What welding method works best with this strip?
A: It offers outstanding spot weldability. It performs very well with resistance spot welding, which is the standard method for battery tab connections.
Q5: Can I customize the dimensions?
A: Absolutely. We offer customization in thickness, width, length, and even pre-cut or punched designs to match your battery pack requirements.
Q6: Why choose nickel plated steel over pure nickel for battery interconnects?
A: Nickel plated steel provides higher tensile strength, better structural support for battery modules, and significantly lower material costs while delivering sufficient conductivity for the majority of applications.
