Nickel Strips for Lithium Batteries

1. Nickel Strips for Lithium Batteries Nickel strips are essential components in lithium-ion battery packs, acting as the conductive bridge between individual battery cells. They enable efficient power transmission, secure mechanical connections, and heat resistance during spot welding. Proper nickel strip selection is critical for safety, performance, and longevity in lithium battery applications. Pure nickel strips, particularly those categorized under Ni200 and Ni201, are essential components in the assembly of lithium-ion batteries such as 18650, 32650, 26650, and 21700 types. These nickel strips are favored for their excellent properties that enhance battery performance and durability. Pure nickel, with its high purity levels, ensures minimal resistance and robust physical integrity, making it ideal for battery connections. This article delves into the characteristics, applications, and benefits of Ni200 and Ni201 pure nickel strips in the context of lithium battery manufacturing. Why Nickel Strips Matter in Lithium Batteries: - Provide electrical pathways between cells - Allow spot welding without damaging cell terminals - Maintain thermal and electrical stability under high current loads Common Applications: - EV Battery Packs (Electric Vehicles) - Power Tools and E-Bikes - Energy Storage Systems (ESS) - DIY Battery Pack Assembly (18650, 21700, etc.) Types of Nickel Strips: 1 Pure Nickel Strip (≥99.6% Ni): - Best electrical conductivity - Superior corrosion resistance - Ideal for high-current battery packs 2. Nickel-Plated Steel Strip: - More affordable alternative - Moderate conductivity - Not recommended for high-current loads or harsh environments 3. Perforated & Slotted Nickel Strips: - Designed to reduce resistance and improve weld quality - Common in high-drain battery systems

2. Specifications to Look For: - Thickness: 0.1 mm, 0.15 mm, 0.2 mm (thicker = more current handling) - Width: 5 mm to 10 mm for common battery types - Resistance Rating: Lower resistance = better performance How to Identify Real vs Fake Nickel Strips: - Magnet Test: Pure nickel is non-magnetic; nickel-plated steel is magnetic - Spark Test: Pure nickel produces shorter, less bright sparks - XRF Analyzer: Verifies chemical composition (industrial use) -Weight Check: Pure nickel is denser than steel Safety and Handling Tips: - Store in dry environments to prevent oxidation - Use gloves to prevent contamination during welding - Avoid bending or over-handling strips to prevent micro-cracks Spot Welding Considerations: - Use pulse spot welder for clean, strong joints - Set proper pulse width and pressure depending on thickness - Ensure clean surface contact between strip and cell terminal Ni200/Ni201 Pure Nickel Strip For 18650/32650/26650/21700 Lithium Battery Specification Pure Nickel Strip For 18650 Strip Thickness 0.01, 0.1, 0.2, 0.05, 0.5 per Customer Requirement Size 3, 3.2, 3.5, 3.6, 3.8, 4.5, 4.57, 4.8, 5, 5.2, 5.5, 7.2 mm and as per Customer Requirement Width 3 mm to 350 mm and as per Customer Requirement Length Coil form Standard JIS, AISI, ASTM, GB, DIN, EN, etc Surface Bright Brand: Technolloy Inc Package Shrink-wrapped, Carton boxes, Wooden pallets, Wooden boxes, Wooden crates Etc. as required. Conclusion: Nickel strips are a critical part of lithium-ion battery design and safety. Choosing the right strip — in terms of purity, thickness, and application — can significantly enhance battery pack performance and durability.
