SHONAN Pure Nickel Strip 99.6% for Battery Packs

Pure nickel strips with 99.6% purity offer excellent corrosion resistance and dependable welding performance for 18650 cells and other battery types. These strips are designed to be spot welded with ease and can be used in nickel electroplating for a bright, durable finish. Users can increase current handling by adding series connections or stacking layers to meet pack requirements. The material’s magnetic properties near room temperature are a noted characteristic that users consider during assembly.
SHONAN Pure Nickel Strips for High Capacity Packs

This 0.15x6mm nickel strip provides a balance between flexibility and strength, making it suitable for spot welding on large-capacity packs. The strips maintain 99.6% purity for longevity and resistance to corrosion, while their hardness supports reliable connections in demanding pack configurations. In addition to battery assembly, they can be used for nickel plating to achieve a bright, corrosion-resistant surface.
SHONAN Thick Nickel Strip for High Capacity Packs

With a thicker profile at 0.2x8mm, these nickel strips are designed for higher current scenarios in battery packs. The 99.6% purity minimizes resistance and promotes lasting connections, while the material’s magnetic nature near room temperature can influence welding settings. The rolls are suitable for direct welding to lithium batteries and for nickel plating applications to enhance appearance and corrosion protection.
HARFINGTON Nickel Strip 0.1mm x 8mm

HARFINGTON offers a nickel-plated steel strip with a thin profile of 0.1mm x 8mm, balancing flexibility and strong weldability. The 15μ nickel layer provides improved oxidation resistance and a robust surface for soldering and spot welding. The roll format supports efficient long-term use, and the bright finish helps identify clean, uniform connections across multiple cells.
HARFINGTON Nickel Strip 0.15mm x 8mm

This 0.15x8mm nickel strip combines good mechanical strength with reliable weldability. The nickel plating contributes to corrosion resistance, helping maintain performance in varied environmental conditions. The roll packaging supports efficient handling and alignment during pack assembly, and the strips can be welded directly to lithium cells or used in nickel plating applications to protect and beautify the finished pack.
NIONSUPPLY 50Pcs 4P Nickel Plated Steel Strips

These nickel-plated steel strips come in a 50-piece pack, featuring 0.15mm thickness and a 4P style configuration. Suitable for DIY 18650 packs, they offer reliable soldering and spot welding capabilities with standard current requirements. The SPCC nickel-treated steel provides a sturdy base with corrosion resistance suitable for hobbyist and light professional assembly projects.
Buying Guide: Key Purchase Considerations
When choosing nickel strips for battery packs, consider purity, thickness, width, and current requirements. Higher purity (around 99.6%) improves corrosion resistance and welding consistency, especially for high-capacity packs. Thicker strips (such as 0.2x8mm) support higher current but may be stiffer to work with in tight layouts. Wider strips (8mm) can provide robust weld areas, reducing resistance at the connection point, while thinner options (0.1mm) offer flexibility for multi-row or compact configurations.
Welding compatibility also matters. Strips labeled as suitable for spot welding are typically optimized for common spot welders used in battery pack assembly. Some strips can also be used for nickel plating, which can enhance corrosion resistance and surface finish. Packaging format—rolls versus sheets or bundles—affects handling, inventory management, and the ability to customize layouts for different pack designs.
Environmental considerations include oxidation resistance and long-term stability under cycling and temperature variation. For larger packs or high-drain applications, evaluate current handling by considering parallel and series connections to scale current ratings safely. Finally, verify compatibility with your cell chemistry (lithium-ion, Li-Po, NiMH, NiCd) and with your welding equipment to ensure clean, repeatable connections.
In summary, top picks combine high purity, suitable thickness, and reliable weldability to deliver consistent performance in battery pack assemblies. The options listed here span thin to thick gauges and standard to high-capacity configurations, helping builders tailor their choice to project requirements and equipment capabilities.
