Lithium is the lightest metal element in nature and is silver-white. Its chemical symbol is Li.  . It ranks first among the IA group alkali metals in the periodic table and is the lightest and most active alkali metal. Because lithium has special physical and chemical properties, it can be used not only as a catalyst, initiator, and additive, but also in the direct synthesis of new materials to improve product performance. Because of its wide range of applications, it is known as "metal monosodium glutamate"; and because lithium has the highest standard oxidation potential among various elements (as indicated by its position in the periodic table), it is the best element for batteries and power supplies.. So it is also called "energy metal". In nature, it mainly exists in the form of spodumene, petalite and lepidolite. Shenzhen Chengxin Lithium Group supplies high-quality lithium chloride, lithium carbonate, lithium hydroxide, lithium metal, spodumene and related derivative products, which are widely used in lithium-ion batteries, energy storage, petrochemical, pharmaceutical and other fields.
