Composite current collector PET/PP copper platingIt is a new type of thin film material that combines PET and PP copper plating, which can effectively resist the effects of high and low temperatures. It has good electrical insulation, heat resistance, corrosion resistance, and arc resistance, and is widely used in the packaging of electronic devices, chip packaging, and sensor manufacturing. The production process of composite current collector PET/PP copper plating is to first treat the surface of PET and PP, then composite them together to cover a layer of copper film, and finally perform heat treatment to form the final composite current collector
PET/PP copper platingComposite current collector PET/PP copper plating has excellent thermal stability, which can effectively resist the effects of high and low temperatures, suppress the deformation and damage of electronic components, and thus improve the reliability of electronic components.
The composite current collector structure is similar to a sandwich, mainly composed of metal material polymer metal material composites. Specifically, it is a new type of composite material that uses polymer films (such as PET, PP, PI, etc.) as substrates and then coats both sides with metal materials (copper or aluminum) to achieve safety, cost reduction, weight reduction, and other goals.
Composite current collectors achieve significant improvements in safety and other aspects, with advantages such as high safety performance, high energy density, low manufacturing cost, long battery life, and high compatibility.
1. High safety performance: Improve the safety of battery mechanical abuse, improve the battery cell interface, and solve the reliability problem of long-term aging catalysis of pure metal current collectors from the material end.
2. High energy density: Composite current collectors are lighter in weight, currently accounting for 15% of the battery weight. PET technology can increase the energy density of battery cells by 5% -10%, achieving high specific capacity.
3. Low manufacturing cost: Compared to traditional foil materials, theoretically composite current collectors can achieve a cost reduction of over 50% (traditional foil materials account for about 10% of battery costs).
4. Long battery life: Polymer materials such as PET and PP have a more uniform surface. Due to the fact that metal crystals are more prone to thermal expansion and contraction, but polymer materials have lower expansion rates and are more prone to vacancy, it is beneficial for maintaining surface integrity and can effectively increase battery life by about 5%.
5. High compatibility: Composite current collectors can be directly applied to various specifications and systems of power batteries such as lithium batteries, solid-state batteries, sodium ion batteries, etc.
In addition, composite current collectors
PET/PP copper platingIt also has good corrosion resistance, which can effectively prevent corrosion of metal surfaces and significantly improve the service life of electronic components.
In short, composite current collector PET/PP copper plating is a very practical technology that can effectively block external electromagnetic waves and resist interference, thereby protecting internal electronic components from external interference. Its application can significantly improve the reliability and stability of electronic components, making it a very practical technology. Therefore, the composite current collector PET/PP copper plating technology is expected to have greater development and application in the future.
