Customized Battery Nickel Sheets: The Reliable Core of Energy Systems
In high-performance battery design, every connection is critical. Our customized nickel sheets are engineered to be the cornerstone of your battery pack's performance, safety and longevity.
Crafted from nickel with over 99.5% purity and precision-rolled to exact thicknesses (0.1mm-1.0mm), each strip delivers stable, ultra-low resistance connections. This minimizes energy loss and heat generation, even under high-current loads.
From compact portable devices to large-scale EV and energy storage systems, our nickel sheets ensure superior electrical performance, mechanical strength and corrosion resistance. More than just conductors, they act as vital safety components-maintaining structural integrity and preventing thermal risks.
Choose our nickel sheets for a reliable foundation that empowers your energy solutions.

FAQ
Q1: How to choose the appropriate thickness of nickel sheet?
A: Mainly selected based on current demand. 0.15mm is suitable for 5A and below, 0.2mm is suitable for 5-8A, and 0.3mm is suitable for 8-15A. At the same time, welding processes need to be considered, with laser welding recommended at 0.15-0.2mm and spot welding recommended at 0.2-0.3mm.
Q2: Why choose pure nickel instead of other materials?
A: Pure nickel has the best conductivity, corrosion resistance, and high temperature stability, and will not form alloys with lithium, avoiding the risk of lithium dendrite penetration and ensuring the highest safety.
Q3: Do nickel sheets need to be processed in advance?
A: Our nickel sheets have been cleaned before leaving the factory and can be used immediately after opening the bag. If stored for a long time, the surface can be wiped with alcohol.
Q4: How to store nickel sheets?
A: It is recommended to seal and store in a dry environment to avoid moisture and corrosive gases. It is recommended to use it as soon as possible after opening.
Q5: How long does the customization cycle take?
A: Sample production takes 3-5 working days, batch production takes 10-15 working days, and urgent service can be shortened to 7-10 days.
Q6: How to ensure product consistency?
A: We use a fully automated production line, with each roll of product having an independent batch number. Samples are taken every 50 meters for testing to ensure consistent performance of the entire roll.
Q7: Do you provide a connection scheme design?
A: Yes, we can provide free connection design services and recommend the optimal nickel sheet specifications and connection methods based on your battery pack structure.
