AL9665 Cathode Foil

Cathode Foil Description

Cathode Foil is manufactured from 1000 and 3007 Series aluminium alloys integrated with an organic coating to offer chemical inertness and dimensional stability. The foil form facilitates uniform application in plating and semiconductor processes while the controlled alloy composition minimises electrical resistance. The tailored coating acts as a barrier against oxidation, supporting critical cathodic processes and ensuring compatibility with standard industrial processing equipment.

Cathode Foil Applications

1.       Electronics
   - Used as a current collector in battery cells to achieve uniform current distribution by leveraging its low electrical resistance and controlled thickness.
   - Applied as a substrate in semiconductor devices to enhance conductive properties by leveraging its smooth, coated surface.

2.       Industrial Processes
   - Employed as a component in plating and etching systems to achieve controlled metal deposition by leveraging its chemically inert organic coating.

3.       Energy Devices
   - Used as a cathodic element in electrochemical cells to achieve efficient ion exchange by leveraging its optimised alloy composition and stable surface characteristics.

Cathode Foil Packing

The Cathode Foil is packaged in an anti-static envelope and secured within a rigid, foam-lined container to prevent mechanical damage and contamination. The packaging design provides a moisture barrier and safeguards against particulate intrusion. It is recommended to store the foil in a temperature-controlled, dry environment. Custom packaging options, including specific dimensions and labelling, are available to match customer requirements.

Frequently Asked Questions

Q1: How is thickness uniformity verified during production?
A1: Optical profilometry and X-ray fluorescence analysis are used to detect micrometre-level variations in thickness. These techniques help ensure each production batch meets the specified tolerances.

Q2: What measures are taken to control surface contamination?
A2: The organic coating is applied in a cleanroom environment, and inline spectroscopic analysis monitors particulate levels. This controlled process minimises surface contamination significantly.

Q3: Can the alloy composition be adjusted for specialised applications?
A3: Yes, modifications in the 1000 and 3007 Series alloy ratios can be implemented based on application-specific requirements, following additional quality evaluations during custom batch trials.
