Lithium is the lightest metal element in nature, the chemical symbol Li, silver white, in the periodic table in the IA group alkali metal first, is the lightest and most active alkali metal. Lithium has special physical and chemical properties. It can be used as catalysts, initiators and additives, and can also be used to directly synthesize new materials to improve product performance. Because of its wide range of applications, it is known as "industrial monosodium glutamate"; In addition, Lithium has the highest standard oxidation potential of various elements, so it is the undisputed best element in the field of batteries and power supplies, so it is also called "energy metal". In nature, it mainly exists in the form of spodumene, petalite and lepidolite.
Chengxin Lithium 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, petrochemicals, pharmaceuticals and other fields.
