0.15mm x 15mm Pure Nickel Strip for Battery Connection

0.15mm x 15mm Pure Nickel Strip for Battery Connection is the premium choice for assembling high-performance, high-current battery packs, particularly those built with 18650, 21700, or other cylindrical lithium cells. Unlike cheaper nickel-plated steel options, this strip uses 99.6% pure nickel, guaranteeing extremely low internal resistance and superior conductivity. This is crucial for applications that demand high discharge rates and efficient charging, minimizing heat generation and maximizing the overall lifespan and performance of your pack. Whether you are building an electric bike battery, a power tool pack, or an energy storage system, this pure nickel strip ensures the strongest, most reliable welds and the most efficient current flow between your cells.

Key Features:

• High Purity (99.6% Nickel): Offers excellent electrical conductivity and extremely low internal resistance compared to nickel-plated steel.
• Superior Weldability: The pure nickel composition provides the best possible adhesion and consistent results when using a spot welder.
• Excellent Corrosion Resistance: Nickel naturally resists oxidation and corrosion, ensuring long-term reliability and performance in various environments.
• Optimal Dimensions: The 0.15mm thickness balances durability and flexibility, while the 15mm width is ideal for high-current paths in parallel connections across multiple cells.
• High Current Capacity: Effectively manages large currents generated by high-draw battery packs without overheating.

Technical Specifications:

• Material Purity: ≥ 99.6% Pure Nickel (Ni200)
• Melting Point: ≈ 1455°C
• Resistivity: Low; optimizes for minimal voltage drop across connections.
• Density: ≈ 8.9 g/cm³

Mechanical Specifications:

• Form: Flat Strip or Coil (Sold by length)
• Hardness: Soft to Medium (Excellent bendability for pack assembly)
• Joining Method: Requires spot welding; can be soldered with specialized high-heat flux.

Dimensions:

• Thickness: 0.15 mm
• Width: 15 mm
• Length: Sold per meter (or in various pre-cut lengths)
• Weight: ≈ 20 g/meter

Pinout and Wiring:

• Note: This is a conductive material, not an electronic component with pins.
• Function: Use the strip to connect the positive terminals of one cell group to the negative terminals of another (series connection) or to connect terminals of the same polarity (parallel connection).
• Installation: Cut the strip to the required length and spot weld it onto the clean, prepared terminals of the battery cells.
