Today's design engineers face growing demands for battery systems that deliver higher power, greater reliability, and lighter weight. Nickel alloys have long been key to meeting these needs, offering exceptional conductivity, weldability, cladding performance, and robust mechanical properties.
In recent years, breakthroughs in higher-purity nickel alloys and advanced processing techniques have opened new possibilities for both current and next-generation battery pack designs - that meet the growing need for increased power, reduced weight, and extended lifespan without compromising performance.
Why Choose Nickel 270 for Batteries?
Nickel 270 (UNS N02270) is the highest-purity commercially available nickel, offering significant advantages over lower-grade cast alternatives in battery tab applications.
With an industry-leading purity 99.98%, this premium alloy reduces impedance and increased electrical conductivity by up to 20% compared to conventional cast materials—making it ideal for high power energy systems.
Additional benefits include:
- Low electrical resistivity for efficient current flow
- Excellent homogeneity and micro-cleanliness for consistent performance
- Tight compositional control that enhances weldability and extends the overall lifespan of the battery
- Reliable cladding performance for unenhanced battery longevity
99.98% Purity through Roll-Compacted Powder
Nickel 270's high purity is achieved through wrought powder metallurgy—a technology that produces strip with mechanical properties uniquely suited for battery applications.
Unlike traditional methods for cast products that introduce impurities during hot rolling, this low-temperature process minimizes non-metallic inclusions. The method involves compacting powder into strip, followed by sintering, densification, homogenization, and further refinement through multiple cycles of cold rolling and thermal treatments.
This "wrought powder metallurgy" process distinguishes
Nickel 270 from other powder metallurgy products, ensuring full densification and superior purity.
Supercharging Electrical Conductivity by 20%
Material purity is essential to conductivity and battery performance. The high purity of Nickel 270 strip reduces impedance and increases conductivity up to 20% compared to conventional cast materials. This enhanced conductivity makes Nickel 270 particularly advantageous for
battery tabs and connectors, enabling efficient connection in battery packs used in NiMH, NiCd, or Li-Ion systems.
Improved Power-to-Weight Ratio in Batteries
Nickel 270’s high conductivity improves power transmission, enabling battery tab miniaturization without compromising power capacity. This makes it possible to produce smaller, lighter connector strips that reduce overall material weight and cost, all while maintaining performance.
These size reductions are especially beneficial in battery applications where weight is critical, such as
electric vehicles, aircraft, and space and satellite electronics.
Superior Weldability for Enhanced Battery Longevity
Nickel 270 strip excels in battery tab applications due to its exceptional weldability. This is driven by its low electrical resistivity which minimizes energy loss during welding, and creates a strong, consistent bond between battery materials - critical for maintaining performance in
high-power systems.
The material’s high thermal and electrical conductivity ensures efficient heat dissipation throughout the welding process, significantly reducing the risk of thermal damage to sensitive battery components. Additionally, our high-purity nickel, produced via roll compaction, offers excellent ductility and a uniform grain structure. This combination prevents cracking and weak joints, resulting in robust, long-lasting welds connections.
Together, these properties contribute to improved durability and extended service life of the entire battery system.
Reliable Cladding Performance for Demanding Energy Applications
Roll compacted nickel, either Nickel 270 or
Nickel 201, is the ideal choice for cladding metals in batteries and electronic applications. These materials offer an unmatched combination of corrosion resistance, superior electrical properties, and outstanding bond integrity.
Due to the minimal impurity content, our nickel strip significantly reduces oxidation. This enables the formation of strong, durable bonds between metallic layers, such as steel or copper for enhanced longevity.
In addition, Nickel’s inherent stability and conductivity make it a cost-effective, high-quality cladding solution. It supports consistent, repeatable cladding processing for all energy heavy applications where reliability is critical.
From EV to AI: Enabling the Future of Batteries
Nickel 270 is mainly used to connect multiple NiMh, NiCd or Li-Ion batteries into a battery pack. These packs power rechargeable devices, such as computers, smart devices, cardiac pacemakers, power tools, electric vehicles, and aerospace batteries. Other battery applications include cathodes and switchgear connections.
Nickel 270 plays a critical role in assembling battery packs by connecting multiple NiMH, NiCd, or Li-Ion cells. These packs are the energy source behind a wide range of rechargeable devices from laptops and smart devices to cardiac pacemakers, power tools, electric vehicles, and aerospace and satellite systems.
As AI-driven digital infrastructure becomes the backbone of modern operations, the demand for reliable battery energy storage especially in
data centers has never been greater. Our pure nickel strip ensures seamless access to backup power when it matters most.
