锂带

Lithium Ribbon


产品介绍 Product introduction

        锂(Li)是一种银白色金属,质软,是密度最小的金属。锂的相对原子质量为6.94,密度为0.534g/cm3 ,熔点为180℃,可与大量无机试剂和有机试剂发生反应,性质极不稳定,遇空气易变质,可与水发生剧烈的反应。因锂的原子量很小,用锂作为阳极的电池具有很高的能量密度。此外,锂电池还具有质量轻、体积小、寿命长、性能好等优点,电池领域已成为锂的最大应用领域。
Lithium (Li) is a kind of silvery white metal, soft, with the minimum density of all metals. Relative atomic mass of lithium is 6.94, with the density of 0.534 g/cm3, melting point of 180℃. Li can react with a large number of inorganic reagents and organic reagents, its chemical property is instable and decomposed easily, react violently with water. Due to the small atomic mass, the battery used lithium as the anode materials has a high energy density. In addition, lithium battery has the advantages of light weight, small size, long lifetime, good performance and so on. The battery field has become the largest application field of lithium.

表面质量Surface quality
        锂带表面平直、光亮,无油斑或其他杂物,无目视可见的氧化物及氮化物,无皱边、孔眼、裂缝、折痕、压线等缺陷,允许有轻微的加工条纹和辊印。锂带的边缘整齐,无裂口,无分层和夹杂。
The surface of lithium ribbon is flat and bright, there are no oil spots, visible oxides and nitride, wrinkles, holes, cracks, creases, trace, other sundries or other defects on the surface, while slight processing stripes and roller printing are allowed. The edge of the lithium ribbon is neat, there are no cracks, no stratification and inclusion at the edge of lithium ribbon.
