Feature
The conductive copper foil has insulation, heat insulation, waterproofing, good adhesion, good cold resistance, and is easy to tear. To eliminate electromagnetic interference (EMI) and isolate the harm of electromagnetic waves to the human body, die-cut double-sided adhesive tape is used to avoid voltage or current effects. In addition, it has a good effect on static discharge after grounding.
Advantages
It features excellent physical properties such as fine grain structure, low profile, and high elongation. In the PCB manufacturing process, it offers the advantages of short circuit etching time and highly uniform circuit etching.
It can effectively contribute to improving the energy density of lithium batteries, provides a stable, conductive substrate onto which the anode active material slurry is coated and rolled.aligning with a major trend in the development of future power battery systems for electric vehicles-lightweighting.
With advantages including light weight, high flexibility, improved electrolyte wetting efficiency, and reduced internal resistance of lithium batteries, it significantly enhances the specific energy and charge-discharge rate of lithium-ion batteries.Copper is electrochemically stable within the operating voltage window of the anode, meaning it does not alloy with lithium.
It exhibits good thermal conductivity, excellent processability, ductility, and formability, along with remarkable resistance to softening and high fatigue strength.Collects and transports electrons generated during the battery's discharge phase to the external circuit. Conversely, it distributes electrons evenly during charging
