Pure nickel strips, particularly those categorized under Ni200 and Ni201, are essential components in the assembly of lithium-ion batteries such as 18650, 32650, 26650, and 21700 types. These nickel strips are favored for their excellent properties that enhance battery performance and durability. Pure nickel, with its high purity levels, ensures minimal resistance and robust physical integrity, making it ideal for battery connections. This article delves into the characteristics, applications, and benefits of Ni200 and Ni201 pure nickel strips in the context of lithium battery manufacturing.
Ni200 and Ni201 are two grades of pure nickel, distinguished primarily by their slight differences in chemical composition and mechanical properties. Ni200 is a commercially pure nickel with a minimum nickel content of 99.6%, while Ni201 has a slightly lower carbon content, making it more resistant to embrittlement at higher temperatures. Both grades exhibit excellent corrosion resistance, high thermal and electrical conductivity, and superior mechanical strength. These properties are crucial in battery applications where consistent performance and longevity are required.
