Factory Supply Lithium bis(trifluoromethanesulphonyl)imide, also known as LITFSI, has the CAS number 90076-65-6. It is a high - quality chemical product offered at a low price. Chemically, its molecular formula is C2F6LiNO4S2. It typically appears as a white to off - white crystalline powder. This product is highly soluble in polar solvents such as acetonitrile and dimethyl carbonate. In terms of its purity, our factory - supplied LITFSI usually has a purity of over 99%, ensuring high - quality performance in various applications. The melting point of LITFSI is around 234 - 238°C, and it has good thermal stability within a certain temperature range.
LITFSI has a wide range of applications in different industries. In the field of lithium - ion batteries, it is an important electrolyte additive. It can improve the conductivity of the electrolyte, enhance the cycling performance and stability of the battery. By using LITFSI, the battery can have a lower internal resistance, which means better charge - discharge efficiency and longer service life. In addition, in the field of electrochemistry, it is used as a supporting electrolyte in various electrochemical systems, such as supercapacitors. It can provide a stable ionic environment for electrochemical reactions, improving the performance of the system. It is also used in the synthesis of some high - performance polymers and other chemical products.
When using LITFSI, it is necessary to follow strict operating procedures. First, it should be stored in a dry and cool environment, away from moisture and high - temperature sources. When preparing the electrolyte solution, appropriate solvents should be selected according to the specific application requirements. For example, in lithium - ion battery electrolytes, common solvents include ethylene carbonate, propylene carbonate, etc. The concentration of LITFSI in the electrolyte should be carefully controlled. Generally, the concentration range is from 0.5M to 1.5M, but this can be adjusted according to the battery design and performance requirements. When handling LITFSI, it is recommended to wear appropriate protective equipment, such as gloves and goggles, to prevent direct contact with the skin and eyes.
Case 1: Lithium - Ion Battery in Electric Vehicles
A well - known electric vehicle manufacturer used our factory - supplied LITFSI in their battery electrolyte. Before using LITFSI, the batteries had issues such as rapid capacity decay after multiple charge - discharge cycles. After adding LITFSI with an optimized concentration of 1M in the electrolyte, the internal resistance of the battery decreased significantly. The battery's capacity retention rate after 1000 charge - discharge cycles increased from 70% to over 85%. This improvement not only extended the lifespan of the battery but also enhanced the driving range of the electric vehicles.
Case 2: Supercapacitor for Energy Storage
A research institution was working on developing a high - performance supercapacitor for energy storage systems. They used LITFSI as the supporting electrolyte in their supercapacitor design. By using LITFSI, the supercapacitor achieved a higher specific capacitance and better charge - discharge stability. The power density of the supercapacitor increased by 20%, making it more suitable for applications that require high - power output in a short period, such as grid - connected energy storage and electric vehicle start - stop systems.
