SUS304 precision stainless steel foil for coin cell battery (18-8 stainless steel) is a typical representative of austenitic stainless steel, containing 18% chromium (Cr) and 8% nickel (Ni), with excellent corrosion resistance, processability and weldability. It has high surface finish, oxidation resistance, acid and alkali resistance, outstanding performance in the atmosphere, fresh water and weak corrosive media (such as food, kitchen equipment), and still maintains good toughness in low temperature environment. The corrosion resistance of SUS304 stainless steel foil can effectively prevent the internal materials of the battery from being corroded in either acidic or alkaline electrolyte environments, ensuring stable battery performance and extending service life. At the same time, it can withstand various pressures and deformations during battery assembly to ensure the integrity of the battery structure.
With these excellent characteristics, SUS304 precision stainless steel foil is widely used in various button batteries, providing long-lasting and stable power support for electronic devices.
