Our High - Quality Lithium Hexafluorophosphate (CAS 21324 - 40 - 3) is a high - purity chemical compound. The chemical formula is LiPF₆. It appears as a white crystalline powder. This product has high purity, usually with a purity level of over 99%, which ensures its excellent performance in various applications.
It has a molecular weight of 151.91 g/mol. Lithium Hexafluorophosphate is sensitive to moisture and should be stored in a dry and cool environment. The density of this product is approximately 1.5 g/cm³, and it has a melting point in the range of 200 - 208°C (decomposition).
Lithium Hexafluorophosphate is mainly used in the field of lithium - ion batteries. It serves as an electrolyte salt in lithium - ion battery systems. In lithium - ion batteries, it helps to conduct ions between the anode and the cathode, enabling the normal operation of the battery. The high ionic conductivity of LiPF₆ ensures efficient charge and discharge processes in the battery, which is crucial for high - performance batteries.
It is also used in some electrochemical research and development. Scientists use it as a key component in experimental electrochemical cells to study the electrochemical properties of new electrode materials and battery systems. Additionally, in some high - energy - density power battery applications, such as electric vehicles and energy storage systems, Lithium Hexafluorophosphate plays an indispensable role in improving battery performance and cycle life.
When using Lithium Hexafluorophosphate, strict safety precautions should be taken. First, it must be handled in a dry and inert gas environment, such as a glove box filled with argon. This is to prevent the product from reacting with moisture in the air, which could lead to the decomposition of LiPF₆ and the generation of harmful hydrogen fluoride (HF) gas.
For the preparation of electrolyte solutions, it is necessary to accurately weigh the appropriate amount of Lithium Hexafluorophosphate and dissolve it in a suitable organic solvent. Commonly used solvents include ethylene carbonate (EC), dimethyl carbonate (DMC), and ethyl methyl carbonate (EMC). The concentration of the electrolyte solution needs to be adjusted according to the specific requirements of the battery system, usually in the range of 1 - 1.5 mol/L.
Case 1: Electric Vehicle Battery
In a well - known electric vehicle manufacturer's R & D project, they used our high - quality Lithium Hexafluorophosphate in their new - generation lithium - ion batteries. By precisely controlling the concentration of the electrolyte solution, they achieved a significant improvement in battery energy density. The new battery had a 15% increase in energy density compared to the previous model, and the cycle life was extended by 20%. This not only improved the vehicle's driving range but also reduced the cost of battery replacement over the vehicle's lifespan.
Case 2: Energy Storage System
A large - scale energy storage system project adopted our Lithium Hexafluorophosphate in its lithium - ion battery energy storage unit. The high - purity LiPF₆ ensured stable ion conduction in the battery, resulting in high - efficiency charge and discharge processes. The energy storage system could quickly respond to the grid's power demand, and its charge - discharge efficiency reached over 90%. This helped to improve the stability of the power grid and effectively store excess electricity during off - peak hours.
