Product Story

Crafted at the Atomic Level: The Precision of Electrodeposition

Among all methods of producing metal foil, electrodeposition (electroforming) is the only process route capable of atomic-level thickness control. Unlike conventional rolling, electrodeposited nickel foil is not thinned by physical rolling; instead, nickel atoms "grow" layer by layer on the cathode surface. Building material at the microscopic scale in this way gives electrodeposited nickel foil a range of unique performance advantages.

CIVEN Metal's electrodeposited nickel foil line covers an ultra-thin range from 5 to 50 microns, with purity above 99.97% (99.99% ultra-high-purity versions available on request). In this thickness range, conventional rolling struggles: the material is too thin to withstand the mechanical stress of multiple rolling passes, while electrodeposition handles it with ease. By precisely controlling current density, electrolyte temperature, pH and additive formulation, we hold every micron of thickness to within ±0.5 μm.

Another unique advantage of electrodeposited nickel foil is its non-oriented crystal structure. Rolled metal foil usually has a distinct rolling texture, making its mechanical properties anisotropic (different strength and ductility in different directions), whereas the grains of electrodeposited foil grow isotropically, delivering consistent performance in every in-plane direction. This is especially important for applications that require uniform stress distribution or conductivity in all directions.

In recent years, with the explosive growth of the EV and energy storage markets, the strategic value of electrodeposited nickel foil as a key battery material has become increasingly clear. In particular, in the development of next-generation storage technologies such as solid-state and sodium-ion batteries, high-purity ultra-thin nickel foil has drawn wide attention for its excellent chemical stability and interface compatibility. CIVEN Metal has positioned itself early in this field and has established joint R&D partnerships with several leading battery companies.

Why CIVEN METAL

Why Choose CIVEN Metal?

🏆 CIVEN Metal's Core Strengths in Electrodeposited Nickel Foil

The quality of electrodeposited nickel foil comes down to purity control, thickness precision and surface quality. CIVEN operates self-designed continuous electrodeposition lines with in-line thickness monitoring and automatic additive dosing, achieving fully digital control from feedstock to finished roll. Our electrolyte circulation and purification system keeps impurities consistently at the ppm level, ensuring stable purity in every batch.

Ultra-High Purity

Standard grade ≥ 99.97%, with 99.99% ultra-high purity available on request. Key impurities such as iron, copper and cobalt are all kept below 10 ppm, meeting the most demanding electrochemical requirements.

Precise Thickness Control

Real-time monitoring by in-line X-ray thickness gauges, with thickness deviation ≤ ±0.5 μm across the full width. Ultra-thin grades from 5 μm, a range most rolling processes cannot reach.

Superior Surface Quality

Double-sided bright or matte finishes available, surface roughness Ra ≤ 0.2 μm. No pinholes, bubbles or organic residue, providing a perfect interface for subsequent coating or lamination.

Isotropic Performance

The non-oriented grain structure formed by electrodeposition ensures consistent mechanical and electrical properties in all in-plane directions. Tensile strength reaches 700–900 MPa, and elongation can be tuned between 2% and 15% depending on heat treatment.

Fast Delivery & Flexible Customization

Standard specifications ship in 5 days; special purity or surface treatment requirements in 10 days. Flexible minimum order quantities help R&D teams accelerate new material validation.

Complete Certifications

ISO 9001 / IATF 16949 dual certification, RoHS compliant. Every shipment comes with a COA and ICP-OES composition analysis report; third-party SGS testing available on request.
