CAS NO:100669-96-3 Sodium Bis(fluorosulfonyl)imide/NaFSI Electrolyte Powder

Starting from the three key aspects of ionic conduction - "carrier concentration, transport channel, and interface resistance", by leveraging its high dissociation property to increase free Na⁺, through the spatial and coordination effects of anions to optimize the microstructure of the electrolyte and construct continuous transport channels, by modifying the interface to eliminate the barriers for ion transmission, and simultaneously enhancing the Na⁺ migration number, ultimately achieving a dual reduction in the phase and interface ionic conduction resistance of the solid-state electrolyte. This is an efficient modifier and core conductive salt component for the solid-state electrolyte of all-solid-state sodium-ion batteries.

The performance improvement brought by supercapacitors is comprehensive and collaborative. The core relies on its high dissociation, high stability, unique ionic structure, and forms a complementary performance with ionic liquids: it not only solves the inherent problems of low ionic liquid conductivity, high interface impedance, and poor low-temperature performance, but also retains and enhances the advantages of ionic liquids such as wide electrochemical window, high thermal stability, and high safety. Ultimately, it achieves comprehensive improvements in the rate performance, cycle life, energy density, operating temperature range, and safety of supercapacitors, making it the preferred conductive component for preparing high-performance, long-life, and wide-temperature-range supercapacitors, and suitable for high-end applications such as new energy, power grids, and aerospace.

Ionic anti-static agents achieve anti-static properties by providing free ions through high dissociation, thereby establishing a continuous ion-conductive pathway. They possess both the long-lasting anti-static effect of internal addition type and the rapid onset characteristic of surface migration type. They eliminate the accumulation of static electricity on the material surface from two aspects: "suppressing charge generation and accelerating charge dissipation".

Under standard sealed storage conditions, the purity shows almost no significant decline and has excellent stability; however, under improper storage conditions such as moisture absorption, contact with air/impurities, high temperatures, etc., the purity will slowly decrease over time. Hydrolysis is the core degradation pathway, accompanied by minor thermal decomposition and side reactions induced by impurities, and the degradation products will further trigger a chain reaction, exacerbating the loss of product purity.
