تفاصيل

Canrd’s MA-EN-CU-0002 copper foil is developed for use as a negative electrode current collector in lithium battery research, particularly suited for experimental and energy material applications. This electrolytic copper foil features a double-sided symmetrical structure with metal density approaching the theoretical value of copper, ensuring low surface contour and enhanced mechanical properties such as high elongation and tensile strength. Available in thickness of 9 μm (with a tolerance of 0 to +3 μm) and widths ranging from 200 to 680 mm, the product supports both single-sided glossy and single-sided rough surface finishes. Common use scenarios include coating and fabricating research electrodes, where weight tolerance of ±5% necessitates pre-testing of empty foil mass for accurate active material loading. Operators should wear gloves to avoid cuts from foil edges and prevent contact with liquids or humid environments to avoid discoloration.

13	Appearance Quality	The copper foil surface shall be flat and free of wrinkles, indentations, impact damage, and oil contamination. The trimmed edges shall be neat, and the surface color shall be substantially uniform. Slight electroplating streaks are acceptable provided that they do not affect anode coating.
14	Storage Conditions	Store at a relative humidity of ≤65% and a temperature of ≤25 °C. Protect the product from corrosive chemicals and do not store it together with damp materials.
15	Shelf Life	Three months from the date of manufacture.

The product has a double-sided symmetrical structure, with a metal density close to the theoretical density of copper, and a very low surface contour. It also has high elongation and tensile strength.

Thickness: 9 μm (0, +3 μm).

Weight tolerance: +/-5%. When using it, it is recommended that the teacher test the specific quality of the empty foil material at the same time to accurately deduct the weight of the foil material corresponding to the coated research electrode.
