In the ever-evolving landscape of energy storage, the performance of lithium-ion batteries and other advanced electrochemical devices hinges critically on the quality of their electrolyte components. Among these, Sodium Bis(trifluoromethylsulfonyl)imide (CAS 91742-21-1) stands out as a high-purity salt essential for achieving superior conductivity, thermal stability, and overall battery longevity. For procurement managers and R&D scientists navigating the complex chemical supply chain, understanding the benefits and sourcing reliable manufacturers is paramount.

Sodium Bis(trifluoromethylsulfonyl)imide, often referred to as Sodium Triflimide or NaTFSI, is characterized by its highly stable bis(trifluoromethylsulfonyl)imide anion and a sodium cation. This unique structure contributes to its excellent electrochemical window and thermal stability, making it an ideal candidate for high-voltage battery applications where conventional electrolytes might falter. As a key electrolyte salt, its role is to dissociate and provide charge carriers, thereby facilitating the movement of ions between the electrodes.

When considering the purchase of this critical material, several factors come into play for B2B buyers. Firstly, purity is non-negotiable. Impurities can significantly degrade battery performance, leading to decreased capacity, shorter cycle life, and even safety hazards. Suppliers offering Sodium Bis(trifluoromethylsulfonyl)imide with a purity exceeding 98%, as is commonly available from reputable manufacturers in China, are preferred. This high purity ensures predictable and reliable electrochemical behavior.

Secondly, the physical form and handling properties are important. Typically supplied as a white to almost white powder or crystal, Sodium Bis(trifluoromethylsulfonyl)imide has a high melting point (around 257-258°C), indicating its thermal robustness. However, it is also noted as being moisture-sensitive, necessitating appropriate storage and handling conditions, such as under an inert gas atmosphere. Understanding these properties allows R&D scientists to better integrate it into their formulation processes.

For businesses looking to buy Sodium Bis(trifluoromethylsulfonyl)imide, partnering with experienced manufacturers and suppliers is crucial. Reputable chemical suppliers in China can offer competitive pricing, consistent quality, and the necessary technical documentation, including certificates of analysis and safety data sheets. This ensures compliance and facilitates smooth integration into production lines. When inquiring about price and availability, it's beneficial to specify your required quantity and purity standards.

The application of Sodium Bis(trifluoromethylsulfonyl)imide extends beyond traditional lithium-ion batteries. It is also a key component in the development of other advanced energy storage systems, including solid-state batteries and supercapacitors, where its unique properties can unlock new performance potentials. For researchers and product developers in the advanced materials sector, sourcing this chemical is a strategic step towards innovation. Contacting a trusted supplier like NINGBO INNO PHARMCHEM CO.,LTD. for a quote or sample can be the first step in securing this vital component for your next project.
