Battery Nickel Strip: Core Conductive Component for New Energy Batteries

Battery nickel strips are thin strips or stamped parts made of high-purity nickel or nickel-based composite materials. They are primarily used to connect individual battery cells in series or parallel, conduct current and provide safety protection. Serving as both the conductive framework and safety fuse for lithium-ion and Ni-MH battery packs.

Main Materials & Selection Guide

Pure Nickel Series (Gold Standard for Battery Applications)

• N6 (99.6% purity): Features excellent spot welding performance, superior corrosion resistance and high electrical conductivity. Ideal for medical devices, industrial equipment and high-rate batteries.
• N4 (99.9% purity): Higher purity grade, designed for applications demanding ultra-high electrochemical stability.

General properties: Low magnetism, excellent ductility and good bending resistance, suitable for complex stamping structures.
