[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."
