Battery grade lithium carbonate is a white crystalline powder containing lithium ions and carbon dioxide. It exhibits unique chemical properties, including being odorless, tasteless, and fully stable under normal conditions to laboratory use. One of its key features is low solubility in water but high solubility in organic solvents, making it suitable for storing over time without degradation.Additionally, battery grade lithium carbonate has excellent physical characteristics such as micro space voids filled with a small amount of air gap and consistent density of around 2.4 to 4.3 g/cm³. These unique properties ensure the material's stability and longevity in various environments where precision is essential.
By effectively preventing moisture and air loss, battery grade lithium carbonate ensures long-term durability and optimal performance during its application.

Product parameters
Battery
grade lithium carbonate is mainly used in the manufacturing of
lithium-ion batteries, which are widely used in electric vehicles,
hybrid vehicles, power tools, household appliances, mobile communication
devices, energy storage systems, medical equipment, photovoltaic energy
storage systems, drones, and aircraft due to their high energy density,
long lifespan, and lightweight characteristics. With the increasing
demand in downstream application fields such as new energy vehicles, the
market demand for battery grade lithium carbonate is also continuing to
rise.
Product Application
In
the industrial field, lithium can be prepared into metallic lithium, a
silver white metallic solid with a melting point of 180.5 ℃ and a
boiling point of 1342 ℃. Its addition can improve the strength,
corrosion resistance, and plasticity of the metal. It can also be used
as a deoxidizer or dechlorination agent in the metallurgical industry,
as well as in the manufacture of special bearing alloys.
In
the aerospace field, the addition of lithium can prepare aluminum
lithium alloys. Compared with traditional aluminum copper alloys, the
strength and stiffness are significantly improved, and the density is
reduced by 3% -5%. It is used in rocket box construction to reduce
rocket weight and improve rocket capacity. Meanwhile, lithium compound
lithium thermoelectric materials, due to their high temperature
stability and high thermoelectric performance, can be used in thermal
control systems, environmental monitoring, and other aspects of
spacecraft. Lithium and its compounds have the characteristics of high
combustion rate, fast speed, wide flame, and large heat generation. The
energy released by 1kg of lithium through thermonuclear reaction is
equivalent to the combustion of over 20000 tons of high-quality coal.
Therefore, lithium is one of the best metals used as rocket fuel.
In
the field of medicine, lithium is prepared into lithium carbonate or
lithium citrate, which can be used to treat mental illnesses such as
bipolar disorder, regulate the central nervous system, calm, stabilize,
and control neurological disorders, and play a positive role in
stabilizing patients' emotions and psychological states. Research has
shown that lithium salts can help prevent cognitive decline in the
elderly and neurodegenerative diseases such as Alzheimer's disease.
In
the field of ceramics, the addition of lithium can prepare lithium
ceramics. Lithium, as a binder, makes the glaze harder and tighter,
while also improving its wear resistance and impact resistance. At the
same time, lithium can change the color of the glaze, resulting in a
"lithium reddening reaction" that affects the redox state of the glaze,
causing it to change from blue to yellow or red.
In
the glass industry, if lithium is added to glass manufacturing, the
solubility of lithium glass is only 1/100 of ordinary glass (about one
ten thousandth of a gram of glass is in each ordinary glass cup of hot
tea). Adding lithium makes the glass "insoluble" and can resist acid
corrosion. Lithium concentrate or lithium compounds have a significant
melting aid effect in the production of glass. Adding them to glass
ingredients can reduce the temperature and viscosity of the melt during
glass melting, simplify the production process, reduce energy
consumption, extend furnace life, increase production, improve operating
conditions, and reduce pollution. In addition, adding lithium compounds
to glass can reduce the coefficient of thermal expansion, improve the
density and smoothness of the glass, and enhance the strength,
ductility, corrosion resistance, and heat resistance of the product.
Lithium containing glass is widely used in chemistry, electronics,
optics, and modern science and technology sectors, and even in daily
necessities.
