Functional material "Micro-porous permeable foil (Al, Cu)"
Materials with a width of 500mm or more can also be manufactured! Effectively reduces the internal resistance of lithium-ion batteries.
"Micro-porous perforated foil (Al, Cu)" is a functional material that has fine perforations with a diameter of 10 microns, formed at over 2000 holes/cm² on Al and Cu thin films. There is no need to change existing production processes or equipment, and it can accommodate both single-sided and double-sided coatings. The perforated aluminum foil and perforated copper foil developed and produced by the manufacturer are widely used in lithium-ion batteries, energy pools, ESS, supercapacitors, electromagnetic wave shielding, thermal management, and heat dissipation, making them ideal materials for collecting liquids. [Features] - Control of hole diameter is possible (etching process) - The surface is hydrophilic - Materials with a width of over 500mm can also be produced - Lithium ions can pass smoothly through the pits - No need to change existing production processes or equipment *For more details, please refer to the PDF document or feel free to contact us.
basic information
**Advantages of Product Performance** - Enhancing battery safety has been verified by many battery manufacturers, confirming its role in safety. - It can directly and effectively improve the specific energy of lithium batteries. - After passing through the holes, the diffusion path of lithium ions can be transformed into a three-dimensional, all-around penetration, thereby improving conductivity. - It can significantly improve the injection efficiency of the electrolyte in lithium batteries, enhancing productivity. - By coating the positive and negative electrodes, surface adhesion can be improved. - The probability of detachment can be greatly reduced, increasing the adhesion between the slurry and the collector surface. - The use of microporous films can accommodate existing production processes such as coating roller presses. *For more details, please refer to the PDF materials or feel free to contact us.*
