In this paper, the properties, preparation methods, application fields and future development prospects of monohydrate lithium hydroxide are discussed.
Chemical name: Lithium hydroxide monohydrate
CAS:1310-66-3
Molecular formula :LiOH·H2O

First, the properties of single-water lithium hydroxide
Lithium hydroxide monohydrate, with the chemical formula LiOH·H₂O, is a white crystalline powder. It is soluble in water and slightly soluble in ethanol and ether. Single-water lithium hydroxide has a higher melting point, about 450°C. In the air, single-water lithium hydroxide will absorb carbon dioxide and gradually change to lithium carbonate. In addition, it is strongly alkaline and corrosive, so extra care should be taken when using and storing it.
Second, the preparation method of single-water lithium hydroxide
The preparation methods of single-water lithium hydroxide are mainly as follows:
1. Lithium carbonate and lithium hydroxide aqueous solution reaction method: the aqueous solution of lithium carbonate and lithium hydroxide is mixed and heated to a certain temperature, so that lithium carbonate is converted into lithium hydroxide. This method is simple to operate, but the cost is high.
2. Lithium ore and limestone melting method: the lithium ore and limestone are melted at high temperatures, and then through water leaching, filtration, evaporation and other steps to obtain single-water lithium hydroxide. This method has a wide range of raw materials but high energy consumption.
3. Electrolysis: By electrolyzing an aqueous solution containing lithium ions, lithium hydroxide can be deposited on the cathode. This method has high efficiency, but the equipment investment is large and the technical requirements are high.
Third, the application field of single-water lithium hydroxide
1. Battery field: single-water lithium hydroxide is one of the important raw materials for lithium-ion batteries. With the popularity of electronic products such as electric vehicles and smartphones, the demand for lithium-ion batteries is increasing, and the market demand for single-water lithium hydroxide is also growing.
2. Ceramic field: single-water lithium hydroxide can be used to prepare ceramic glazes, ceramic pigments, etc. In the ceramic industry, the application of single-water lithium hydroxide helps to improve the quality and performance of ceramic products.
3. Glass field: single-water lithium hydroxide can be used to prepare special glass, such as high-refractive index glass, anti-reflection glass, etc. These special glasses are widely used in optical instruments, aerospace and other fields.
Fourth, the future development prospects of single-water lithium hydroxide
With the rapid development of new energy, new materials and other fields, the market demand for single-water lithium hydroxide will continue to grow. At the same time, with the continuous progress of science and technology, the preparation method and application field of single-water lithium hydroxide will continue to expand. In the future, single-water lithium hydroxide is expected to be applied in more fields and make greater contributions to the development of human society.
However, there are some problems and challenges in the production and application of monohydrate lithium hydroxide. For example, pollutants such as waste water and waste gas generated in the production process need to be effectively treated to avoid pollution to the environment. In addition, the price of single-water lithium hydroxide is greatly affected by raw materials, energy prices and other factors, and enterprises need to strengthen cost control and improve market competitiveness.

V. Conclusion
As an important inorganic compound, lithium hydroxide is widely used in battery, ceramics, glass and other fields. With the rapid development of new energy, new materials and other fields, the market demand for single-water lithium hydroxide will continue to grow. In the future, we look forward to more scientific and technological innovation and industrial development to promote the continuous progress and development of the single-water lithium hydroxide industry. At the same time, we also call on enterprises to strengthen their awareness of environmental protection and responsibility, and actively promote green production and sustainable development.
