Lithium Hydroxid. Monohydrate/Anhydrous Highpuritybatterygradelithium Salt Preparation Organic Intermediates CAS

Product Description

Chemical Properties and Structure

Lithium hydroxid. (LiOH) can exist in two main forms: monohydrate (\(LiOH\cdot H_2O\)) and anhydrous (LiOH).
Lithium hydroxid. Monohydrate 
The chemical formula of Lithium hydroxid. monohydrate is \(LiOH\cdot H_2O\). It has a molar mass of approximately 41.96 g/mol. In its solid state, it appears as a white, crystalline powder. The structure consists of lithium cations (\(Li^+\)) and hydroxide anions (\(OH^-\)) along with water molecules incorporated into the crystal lattice through hydrogen bonding. The water molecules in the monohydrate form play a role in the compound's physical properties, such as solubility and thermal behavior. It is highly soluble in water, dissociating into \(Li^+\) and \(OH^-\) ions.
Lithium hydroxid. Anhydrous 
Anhydrous Lithium hydroxid. (LiOH) has a molar mass of about 23.95 g/mol. It is also a white, crystalline solid. Without the water of hydration, the anhydrous form has a more compact crystal structure composed solely of lithium and hydroxide ions held together by ionic bonds. Anhydrous Lithium hydroxid. is also soluble in water, but its solubility characteristics may differ slightly from the monohydrate form due to the absence of water molecules in the crystal lattice.

Quality Assurance

Our production process for high - purity Lithium hydroxid. (both monohydrate and anhydrous) adheres to strict quality control measures. We start with high - quality lithium - containing raw materials, carefully selected to ensure the purity of the final product.
During production, multiple analytical techniques are employed to monitor and control the quality. Inductively coupled plasma - optical emission spectrometry (ICP - OES) is used to detect and quantify trace metal impurities, ensuring that they are kept at extremely low levels, which is crucial for battery - grade applications. Thermogravimetric analysis (TGA) is used to accurately determine the water content in the monohydrate form or to confirm the anhydrous nature of the product. The particle size distribution of the powder is also closely monitored to ensure consistent flowability and reactivity. Our production facilities comply with international quality management systems, such as ISO 9001, and relevant battery - material and chemical - intermediate standards.

Applications

Battery Industry 
In the battery industry, high - purity Lithium hydroxid. is a key raw material for the production of lithium - ion batteries. Lithium - ion batteries are widely used in portable electronics, electric vehicles, and energy storage systems. Lithium hydroxid. is used to synthesize cathode materials, such as lithium - nickel - cobalt - manganese - oxide (NCM) and lithium - cobalt - oxide (LCO). The high purity of Lithium hydroxid. is essential as impurities can significantly affect the performance, safety, and lifespan of the batteries. For example, trace amounts of certain metals can cause unwanted side - reactions during battery charging and discharging, leading to capacity degradation over time.
Organic Synthesis 
Lithium hydroxid. serves as an important organic intermediate. It can be used in various chemical reactions, such as the synthesis of esters, ethers, and other organic compounds. In the medicinal industry, it may be involved in the synthesis of certain drugs. Its ability to act as a base in organic reactions allows for the formation of chemical bonds and the transformation of organic molecules. For instance, it can react with carboxylic acids to form lithium carboxylates, which are useful intermediates in the production of fine chemicals.
Air Treatment 
Lithium hydroxid. is also used in air - treatment systems, especially in spacecraft and submarines. It can absorb carbon dioxide (\(CO_2\)) from the air through a chemical reaction. The reaction between Lithium hydroxid. and carbon dioxide forms lithium carbonate (\(Li_2CO_3\)) and water (\(H_2O\)). This property makes it an effective means of removing carbon dioxide from confined spaces, ensuring a breathable environment for occupants.

Packaging and Storage

Our high - purity Lithium hydroxid. (monohydrate and anhydrous) is packaged to ensure its quality during storage and transportation. For small - scale users, such as research laboratories, we offer 1 - kilogram and 5 - kilogram plastic - lined paper bags. These bags provide good protection against moisture absorption, which is important as Lithium hydroxid. is hygroscopic.
For large - scale industrial users, we provide bulk packaging in 25 - kilogram multi - layer paper bags or in sealed steel drums. The steel drums are suitable for long - distance transportation and storage. When it comes to storage, Lithium hydroxid. should be stored in a cool, dry, and well - ventilated area. It should be kept away from sources of heat, ignition, and acidic substances. The storage temperature should be maintained within a range of 5°C - 35°C to prevent any potential degradation of the product.

Safety and Handling

When handling high - purity Lithium hydroxid., appropriate safety precautions must be taken. Lithium hydroxid. is corrosive to the skin, eyes, and respiratory system. Workers should wear appropriate personal protective equipment (PPE), including chemical - resistant gloves, safety goggles, and respiratory protection if necessary.
In case of skin contact, the affected area should be immediately washed with plenty of water for at least 15 minutes. If Lithium hydroxid. gets into the eyes, immediate and prolonged irrigation with clean water is required, followed by seeking medical attention. In case of inhalation, the person should be moved to an area with fresh air. If respiratory problems persist, medical help should be sought. Our product comes with a detailed safety data sheet (SDS) that provides comprehensive information on safety, handling, and emergency procedures.
