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. In addition, lithium can also be used in nuclear reactor, producing light alloys. Lithium is a light rare metal with broad application prospects. As one of the important elements to promote the development of science and technology in the 21st century, lithium is known as "energy star" by scientists.

     Lithium has the advantages of light weight, high working voltage, constant internal resistance and high specific energy, and it even can withstand large current discharging. Because of these advantages, lithium is often used as anode materials of lithium manganese, lithium iron, lithium fluorocarbon and other primary batteries. 

      1. The lithium ribbon shall be treated in an inert gas or in dry air, and its storage period shall be six months.

      2. The lithium ribbon is wound around the reel, which is sealed with argon in the Al-laminated bag in a dry environment. The size of the reel depends on the quantity of the lithium ribbon ordered.

      3. The specific packaging specifications are as follows:
