Perforated aluminum foil with fine through-holes, "Toyal Pass."
Functional material with fine through-holes of 1 micron or less in diameter formed in aluminum foil.
"Toyarupasu (Perforated Foil)" is a functional material that has fine perforations with a diameter of less than 1 micron formed in aluminum foil. It is currently used as a current collector for the positive electrode of "lithium-ion capacitors." [Features] - By adjusting the etching conditions, the number, density, and diameter of the perforations can be changed. - Due to the fine holes, there is no coating loss, allowing for process simplification. - The pre-doping is uniform and the resistance value is low. - By applying etching, the oxide film becomes thinner, reducing surface resistance. *For more details, please refer to the catalog, and feel free to contact us.
