1:Overview of lithium applications

  Lithium is widely used in batteries, ceramics, glass, lubricants, refrigeration fluids, nuclear industry, optoelectronics and other industries. With the continuous development of electronic products such as computers, digital cameras, mobile phones, and mobile power tools, the battery industry has become the largest consumer field of lithium. In addition, lithium carbonate is one of the effective ways to reduce energy consumption and protect the environment in the ceramic industry, and the demand for lithium will also increase. At the same time, various new roles of lithium in glass are constantly being discovered, and the demand for lithium in the glass industry will continue to grow. Therefore, the glass and ceramic industry has become the second largest consumer area for lithium.

2:Battery industry

Due to the small atomic weight of lithium, batteries using lithium as an anode have a high energy density. In addition, lithium batteries have the advantages of light weight, small size, long lifespan, good performance, and pollution-free, making them highly favored. In recent years, the application of lithium in the battery industry has grown the fastest, from 7% in 1997 to 35% in 2013. The battery industry has become the world's largest consumer of lithium. Nowadays, lithium batteries have been widely used in fields such as laptops, mobile phones, digital cameras, small electronic equipment, aerospace, electromechanical, and military communication. With the continuous maturity of electric vehicle technology, lithium batteries will also be widely used in the automotive industry.

3:Glass industry

 Lithium concentrate or lithium compounds have a significant melting aid effect in glass manufacturing. Adding them to glass ingredients can reduce the temperature and viscosity of the melt during glass melting, simplify production processes, reduce energy consumption, extend furnace life, increase production, improve operating conditions, and reduce pollution. In addition, adding lithium compounds to glass can also reduce the coefficient of thermal expansion of glass, improve the density and smoothness of glass, and improve the strength, ductility, corrosion resistance, and heat resistance of products. Lithium containing glass is now widely used in the fields of chemistry, electronics, optics, and modern science and technology, and even in daily necessities.

4:Ceramic industry

 Adding a small amount of spodumene to ceramics can lower the sintering temperature, shorten the sintering time, improve the fluidity and adhesion of ceramics, increase the strength and refractive index of ceramics, and enhance the heat resistance, acid resistance, alkali resistance, wear resistance, and heat resistance of ceramics. Now, spodumene based low thermal expansion ceramics and low thermal expansion glazes made of spodumene are widely used in trays, electromagnetic cooker panels, turbine blades, spark plugs, low thermal expansion coefficient foam ceramics and lightweight ceramics in microwave ovens.

5:Other applications

 Lithium metal is used as coolant in nuclear fusion or nuclear fission reactors because of its large heat capacity, wide range of liquid temperature, high thermal conductivity, low viscosity and low density.

Lithium bromide is an efficient water vapor absorber and air humidity regulator, widely used in air conditioning, dehumidification, refrigeration, and air purification systems.

Lithium and its compounds have the characteristics of high combustion rate, fast speed, wide flame width, and high heat generation, and are often used as high-energy fuels for rockets, aircraft, or submarines.

Lithium can also be used to produce "lithium salt fertilizers" to prevent tomato decay and wheat rust.

Adding lithium salt to aluminum electrolysis cells can improve the fluidity of molten salt, reduce electrolysis degree, and significantly save electricity.

N-butyl lithium is also used as an initiator for the synthesis of styrene and butadiene alcohol, and is widely used in high-temperature and low-temperature resistant rubber sealing materials and rubber tires. The addition of butyl lithium to rubber tires can increase their lifespan by more than four times.
