[Technical Document] The coating technology for active materials on current collector aluminum foil is a technical document related to the coating technology of active materials, which is essential for the rapidly growing markets of lithium-ion batteries and EDLCs. Toyo Aluminum not only manufactures aluminum foil but also possesses various processing technologies, including coating on aluminum foil. This document will introduce the coating technologies used in die coaters and comma coaters.

NBCR soft aluminum foil is a developed alloy aluminum foil used for deep and sharp molded products that could not be achieved with conventional packaging grade aluminum foil. This document provides technical information regarding the high moldability and laminate suitability of NBCR soft aluminum foil.

Aluminum foil is produced by "rolling" a coil of aluminum sheet, known as foil stock, multiple times. In addition, it goes through processes such as "separation," "annealing," "slitting," and "inspection" before being shipped. We have created simple and easy-to-understand materials that can be understood even by those who have never handled aluminum foil.

Aluminum is used as a versatile material in various applications and industries, taking advantage of its excellent properties such as being "light," "strong," "highly resistant to corrosion," "easy to process," "good at conducting electricity," and "reflective of light and heat."

Toyo Aluminum has been engaged in the development of various functional aluminum foils as a leading company in the aluminum foil market since 1931. Focusing on the three core technologies in the aluminum foil field—"material design technology," "surface control technology," and "powder adhesion technology"—we will continue to create new materials. This product is an aluminum foil that achieves 1.2 times the mechanical strength compared to conventional products, thanks to our material design technology. It contributes to solving the challenges faced by those who have adopted copper or stainless steel foils due to mechanical strength, as well as those dealing with issues stemming from insufficient mechanical strength of existing aluminum foils. 【Features】 - Achieves high mechanical strength through material design technology - Balances high mechanical strength with thin foil, with a minimum thickness of 9μm - Even in "soft" form, treated for improved ductility and surface degreasing, it achieves mechanical strength superior to conventional products - Also possesses corrosion resistance against saltwater and weak acids/weak alkalis *Please refer to the catalog for data on tensile tests and corrosion tests.
