SPCC nickel plated steel strip is widely used in lithium battery pack assembly, especially for 18650 battery spot welding applications. From our DLX perspective, this material is designed to combine the strength of cold rolled steel (SPCC substrate) with the excellent conductivity and corrosion resistance of a nickel coating. The double-sided nickel plating structure improves welding consistency, reduces contact resistance, and enhances long-term reliability in battery modules.
With thickness options ranging from 0.1mm to 0.3mm, this strip is commonly used in battery connection systems where stable current flow and mechanical strength are both critical. In modern energy storage and power battery industries, this material has become a standard choice for battery pack assembly lines.
Material Structure Explanation
This product is not just a simple steel strip. It is a layered composite material:
-
Base material: SPCC cold rolled steel
-
Coating layer: High-purity nickel plating on both sides
-
Surface condition: Smooth, low roughness for stable spot welding
-
Thickness range: 0.1mm – 0.3mm
The SPCC base provides mechanical strength and flexibility, while the nickel coating improves electrical conductivity and corrosion resistance. This combination is essential for battery pack safety and performance stability.

From DLX production experience, this nickel plated steel strip is mainly used in:
-
18650 lithium battery pack connections
-
Power tools battery packs (drills, saws, etc.)
-
Electric bicycle battery modules
-
Energy storage systems (ESS)
-
Portable power banks
-
Battery tabs and busbar connections
In all these applications, spot welding reliability directly affects battery performance and safety.
Industry Trends
The demand for SPCC nickel plated strips is growing fast due to the expansion of:
-
Electric vehicles (EV) supply chains
-
Renewable energy storage systems
-
High-capacity consumer electronics
-
Industrial backup power systems
Manufacturers are now shifting from traditional nickel strips to cost-optimized nickel plated steel strips. This trend is driven by cost pressure and performance balancing. Pure nickel strips are expensive, while SPCC nickel plated steel provides a more economical solution without sacrificing core welding performance.
At DLX, we see increasing demand for double-sided plating because it improves welding stability and reduces rejection rates in automated production lines.
Real Problems in Production
In real battery manufacturing environments, customers often face the following issues:
-
Weak spot welding strength
If the nickel coating is uneven or too thin, welding points can easily fail under vibration. -
High electrical resistance
Poor plating quality increases internal resistance, reducing battery efficiency. -
Corrosion in humid environments
Without proper nickel coverage, steel base material can rust over time. -
Inconsistent thickness tolerance
Even small deviations in thickness can affect welding machine calibration. -
Poor batch stability
Some suppliers cannot maintain consistent plating thickness across large rolls.
DLX addresses these issues through controlled plating processes and strict dimensional inspection systems.
Parameter Explanation
Understanding key parameters helps buyers choose the right specification:
-
Thickness (0.1–0.3mm): Affects mechanical strength and welding energy requirement
-
Nickel coating thickness: Determines corrosion resistance and conductivity
-
Tensile strength: Ensures strip does not break during forming or winding
-
Surface roughness: Impacts welding consistency and contact quality
-
Width tolerance: Important for automated cutting and battery assembly lines
In battery pack manufacturing, even small deviations in these parameters can significantly impact final performance.

Company Comparison Perspective
From a general market perspective, many suppliers focus mainly on cost and mass production. However, DLX focuses on process stability and application performance.
Typical suppliers often prioritize output volume, which can lead to variations in nickel plating thickness and inconsistent welding results. In contrast, DLX focuses on:
-
Controlled electroplating process parameters
-
Continuous coating thickness monitoring
-
Strict surface defect elimination
-
Batch-to-batch stability assurance
This difference becomes especially important for high-end battery applications where failure is not acceptable.
From our DLX manufacturing experience, we understand that battery manufacturers are not just buying a metal strip—they are buying stability in production.
Our advantages include:
-
Stable double-sided nickel plating for consistent conductivity
-
Better welding yield rate in automated spot welding systems
-
Reduced production downtime caused by material inconsistency
-
Improved battery pack safety due to uniform resistance distribution
-
Custom thickness and width support for different battery designs
In real production environments, these advantages translate into lower rejection rates and higher assembly efficiency.
Industry Outlook
As battery energy density increases and pack designs become more compact, material requirements are also becoming stricter. Future trends include:
-
Thinner but stronger strips (below 0.1mm in advanced designs)
-
Higher precision plating control
-
Lower resistance connection materials
-
Eco-friendly and recyclable battery materials
DLX continues to invest in process optimization to meet these evolving requirements.
