Aluminum foil with excellent strength and ductility for the positive electrode current collector of lithium-ion secondary batteries.
We have developed aluminum foil 'KS-81' suitable for improving processing and coating precision, as well as output density, for lithium-ion secondary battery positive electrode current collectors. Thanks to improvements in foil manufacturing technology and foil rolling technology, it has become a very fine metal crystal with high mechanical properties. Additionally, it can be used without compromising processability or basic performance due to the thinning of the aluminum foil. 【Features】 ■ Excellent strength and ductility ■ Ensures conductivity almost equivalent to pure aluminum ■ Offers a wide range of thickness options and can accommodate thinning ■ Cost reduction possible through thinning *For more details, please refer to the catalog or feel free to contact us.
