Nickel Strip, for 18650 for Spot Welding (1 kg)

H - SHAPE Lifepo4 Battery 2p Pure Nickel 0.15 * 45mmThe 32650 Spot Welding COATED Nickel Strip H - SHAPE LiFePO4 Battery 2p Pure Nickel 0.15 * 45mm for Lithium Battery is a premium-quality, coated nickel strip designed for use in lithium battery assembly, specifically for LiFePO4 (Lithium Iron Phosphate) batteries. This coated strip is engineered to ensure efficient, safe, and durable connections between individual cells in a battery pack. Below is a detailed description of its features and applications:

1. Nickel Strip Specifications

• Material: The strip is made from pure nickel, which is widely regarded for its excellent conductivity and strength. Nickel provides reliable electrical connections and resistance to corrosion, making it a perfect choice for lithium battery applications.
• Thickness: The strip has a thickness of 0.15 mm, offering an optimal balance between flexibility, strength, and current-carrying capacity. This thickness ensures it can be spot-welded easily to battery cells while maintaining performance.
• Width: The strip is 45 mm wide, which is ideal for use in larger battery pack configurations, where wider strips can handle more current and facilitate better electrical connections across multiple cells.
• Coated Surface: The strip is coated, which serves several purposes:
  • Improved Weldability: The coating helps achieve a stronger, more stable spot weld when joining the nickel strip to battery cells.
  • Corrosion Protection: The coating acts as a protective layer, reducing the likelihood of corrosion or oxidation, which can degrade the quality of the connection over time.
  • Enhanced Durability: The coating increases the lifespan of the nickel strip by shielding it from environmental elements like moisture or salts that may cause degradation in uncoated materials.

2. Battery Compatibility

• Battery Type: This nickel strip is designed specifically for LiFePO4 (Lithium Iron Phosphate) battery cells, which are known for their stability, high safety standards, and long lifespan. The strip's coating helps protect the cells from corrosion and contributes to overall battery reliability.
• Cell Configuration: The "2p" in the description refers to the parallel cell configuration. In a 2p configuration, two cells are connected in parallel to increase the overall capacity (amp-hour rating) of the battery pack. The strip is ideal for joining two cells in this way to form part of a larger battery pack.

3. Spot Welding Application

• Spot Welding: This nickel strip is designed for use in spot welding technology, where high current is applied to create a strong and permanent bond between the strip and the battery cell terminals. The coating helps facilitate a cleaner and more efficient weld by ensuring the connection is secure and reliable.
• Weld Strength and Reliability: With the combination of pure nickel and a coating, the strip ensures that the spot welds are strong and can withstand the high current loads that occur during charging and discharging cycles.

4. Performance and Safety Features

• High Conductivity: Pure nickel offers excellent electrical conductivity, allowing for smooth power flow between battery cells, ensuring high performance and minimal energy loss.
• Corrosion Resistance: The coating further enhances the strip's resistance to environmental factors, making it suitable for long-term use in various applications without degradation from humidity or other elements.
• Thermal Stability: The pure nickel material, combined with the coating, also enhances the strip's ability to withstand high temperatures during both operation and the spot welding process.

5. Applications

• Battery Pack Assembly: The strip is primarily used in the assembly of LiFePO4 battery packs, where high performance, safety, and reliability are essential. It’s ideal for creating high-capacity energy storage systems such as those found in electric vehicles (EVs), solar energy storage systems, and large battery banks.
• DIY Projects: It is also popular among hobbyists and DIY enthusiasts who are building their own battery packs for applications such as electric bicycles, power tools, robotics, or solar power systems.
• High-Power Devices: The strip is designed for use in high-power devices that require a safe and efficient means of connecting cells in parallel to increase the overall current capacity of the battery pack.

6. Advantages of Coated Nickel Strip

• Improved Spot Welding Performance: The coating allows for a more consistent and reliable spot welding process, ensuring that the electrical connections are strong and secure.
• Enhanced Safety: The corrosion-resistant properties of the coating reduce the risk of degradation and failure, contributing to the overall safety of the battery pack.
• Increased Lifespan: The coating helps protect the nickel strip from wear and tear over time, leading to a longer lifespan for both the strip and the battery pack it is used in.

7. Packaging and Delivery

• The nickel strip is typically sold in rolls or pre-cut pieces, with dimensions carefully measured to make assembly easier. It is designed for easy handling and can be cut to the required lengths for specific battery pack designs.
