Directory Guidance on Lithium Bromide
Product Introduction:
Lithium Bromide (LiBr) is a white crystalline solid with unique physical and chemical properties. It is stable at room temperature, not volatile, and does not react with oxygen in the air, so it has good chemical stability. It is very hygroscopic and can quickly absorb water vapor in the air. This characteristic makes it widely used in the fields of dehumidification and refrigeration.
Lithium Bromide’s solubility is another distinguishing feature. It can dissolve in water to form a colorless and transparent solution, and its solubility increases with temperature. This high solubility allows Lithium Bromide solution to effectively absorb and release refrigerant when used as an absorbent in an absorption refrigerator to achieve a refrigeration cycle.
In terms of safety, Lithium Bromide solution is non-toxic, environmentally friendly and has no ozone depletion potential (ODP) and global warming potential (GWP), making it an environmentally friendly refrigerant choice. Additionally, its solutions are relatively less corrosive, but still require appropriate materials and anti-corrosion measures to protect equipment.
One of its advantages is its high energy efficiency. Lithium Bromide absorption chillers can use low-grade heat sources, such as industrial waste heat, solar energy or geothermal energy, which are often wasted in traditional refrigeration systems. This type of chiller has lower operating costs because it reduces reliance on electricity, especially where electricity costs are high.
Finally, Lithium Bromide refrigeration systems are favored for their low noise and long life. Because its working principle involves fewer mechanical moving parts, it operates with less noise. At the same time, the chemical stability and low corrosiveness of Lithium Bromide solutions help extend the service life of equipment and reduce maintenance costs and replacement frequency.

What Are The Uses of Lithium Bromide
Product service:
Lithium Bromide (LiBr) is a widely used chemical substance. Its unique hygroscopicity, high solubility and good thermodynamic properties make it play an important role in many fields.
1. Air conditioning and refrigeration technology
The most widely used application of Lithium Bromide is in absorption refrigeration systems. Because its solution can effectively absorb water and release heat at low temperatures, it is used as a refrigerant in absorption refrigeration technology. Lithium Bromide aqueous solution can drive the refrigeration cycle by absorbing and releasing heat, using low-temperature heat sources (such as waste heat, solar energy, etc.).
This refrigeration system is usually used in industrial environments, large buildings or cold chain logistics where a lot of cooling is required. Compared with traditional compression refrigeration systems, absorption refrigeration systems are more energy-saving and environmentally friendly, can reduce operating costs and reduce the burden on the environment, and are particularly suitable for energy-saving buildings and environmentally friendly industrial applications.
2. Desiccant and desiccant
Because Lithium Bromide has strong hygroscopicity, it is widely used in desiccants and desiccant. In moisture control systems, it can quickly absorb moisture from the air and keep it in solution. It is usually used to control the humidity of the experimental environment, protect equipment from moisture damage, etc.
In the industrial field, it is used as a humidity regulator, such as air conditioning equipment, dehumidifiers, refrigeration facilities, etc. Especially in the production of high-precision electronic equipment, aerospace, medicine and other industries with strict humidity requirements, the application of Lithium Bromide as a moisture absorber is crucial.
3. Chemical synthesis and catalysis
Lithium Bromide is also used in some chemical reactions, mainly as a solvent, catalyst or reaction intermediate. It participates in certain organic chemical reactions, such as for the generation of brominated organic matter or as a solvent in electrochemical reactions.
In addition, it is also used in electrolytes and electrolytes, especially in electrolytic reactions, it can sometimes help reactants dissolve and improve reaction efficiency. Due to its good chemical stability and high solubility, Lithium Bromide has unique application value in the field of chemical synthesis.
4. Lithium battery technology
Lithium Bromide also has certain application potential in the research of lithium batteries. Although it is not a mainstream electrolyte, it has been studied for use in battery systems in high-temperature environments in some special cases. Its good ionic conductivity and high solubility make it potentially useful in certain extreme conditions. In addition, its use in battery design, especially in studies involving solvents and electrolytes, may provide new ideas for optimizing the performance of new lithium batteries.
5. Medicine and Biology
Lithium Bromide also has important applications in the medical field. It can be used to prepare antidepressants, sedatives, and anti-epileptic drugs. In addition, it can also be used to treat diseases such as hyperthyroidism and mental illness. It has been widely used in the medical field due to its good biocompatibility and low toxicity.
6. Environmental and new energy applications
In sustainable energy technology, the hygroscopic properties of Lithium Bromide are also used in energy storage systems and heat recovery devices. For example, in thermal energy storage devices, its solution is used to store and transfer heat, thereby improving energy efficiency. In addition, Lithium Bromide is also used as a moisture absorbent in some new environmentally friendly materials to reduce the corrosive effects of moisture on equipment and buildings.
7. Other applications
In addition to the above fields, Lithium Bromide can also be used as a material for regulating the chemical environment in some industrial production processes. For example, in some gas cleaning processes, it is used to remove impurities in hydrogen sulfide or other gases. It can also be used in some water treatment processes to regulate water quality by reacting with ions in water. In the electronics and power industries, it can also be used as a coolant and humidity control agent to help extend equipment life and improve performance.
Lithium Bromide is widely used in many fields due to its strong hygroscopicity, good chemical stability and thermodynamic properties, especially in air conditioning and refrigeration, desiccant, chemical synthesis, lithium batteries and pharmaceutical research. It shows great application potential in energy saving, environmental protection and improving equipment efficiency, and has become one of the indispensable materials in modern industry and technology.
Safety Precautions of Lithium Bromide
Lithium Bromide (LiBr) is a chemically relatively stable compound, but its safety still needs attention. Although it has a wide range of applications in various industrial and scientific research fields, due to its certain corrosiveness and strong hygroscopicity, appropriate safety measures must be taken during handling and use.
1. Toxicity and Hazards
Lithium Bromide itself has low direct toxicity to the human body, but its safety still needs to pay attention to the following aspects:
Inhalation hazard: Inhalation of Lithium Bromide dust or vapor may cause irritation to the respiratory tract, especially in the case of high concentration exposure, which may cause symptoms such as coughing, sore throat, and shortness of breath.
Skin contact: Lithium Bromide solution or powder contacting the skin may cause mild irritation, and long-term contact may cause skin allergic reactions. Although it is less corrosive, if Lithium Bromide solution stays on the skin for a long time, it may cause redness, swelling or irritation.
Eye contact: If Lithium Bromide solution or dissolved dust enters the eyes, it may cause eye stinging and tearing, and in severe cases, it may cause corneal damage or inflammation. Eye exposure needs to be rinsed immediately with plenty of water.
Ingestion: Ingestion of small amounts of Lithium Bromide usually does not cause serious poisoning, but may cause gastrointestinal discomfort such as nausea, vomiting, abdominal pain, etc. Large doses may cause more serious poisoning reactions, including central nervous system symptoms such as dizziness, fatigue, and even coma.
2. Corrosiveness
Lithium Bromide solution is corrosive to a certain extent, especially for metals, glass and other materials. During use, special attention should be paid to its solution to avoid direct contact with metal materials or other easily corrosive surfaces to avoid damage. Long-term exposure to high concentrations of Lithium Bromide solution may cause corrosion to some metals, especially at high temperatures.
3. Hygroscopicity and reactivity
Lithium Bromide has strong hygroscopicity. It easily absorbs moisture in the air and forms a solution. If the air humidity is high, it is easy to absorb water from a solid to a solution, which may cause the solution in the container to overflow, especially when the seal is not good. Therefore, it is necessary to avoid a high humidity environment during storage and use to prevent it from over-reacting with moisture.
Although Lithium Bromide itself is not prone to violent chemical reactions, it is still possible to react when it comes into contact with water or other strong reducing agents or acidic substances, resulting in increased solubility or intensified chemical reactions in the solution. Therefore, it should be avoided from mixing with these substances.
