Lithium Ribbon
鋰(Li)是一種銀白色金屬，質(zhì)軟，是密度最小的金屬。鋰的相對原子質(zhì)量為6.94，密度為0.534g/cm3 ，熔點為180℃，可與大量無機(jī)試劑和有機(jī)試劑發(fā)生反應(yīng)，性質(zhì)極不穩(wěn)定，遇空氣易變質(zhì)，可與水發(fā)生劇烈的反應(yīng)。因鋰的原子量很小，用鋰作為陽極的電池具有很高的能量密度。此外，鋰電池還具有質(zhì)量輕、體積小、壽命長、性能好等優(yōu)點，電池領(lǐng)域已成為鋰的最大應(yīng)用領(lǐng)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.
表面質(zhì)量Surface quality
鋰帶表面平直、光亮，無油斑或其他雜物，無目視可見的氧化物及氮化物，無皺邊、孔眼、裂縫、折痕、壓線等缺陷，允許有輕微的加工條紋和輥印。鋰帶的邊緣整齊，無裂口，無分層和夾雜。
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.
