NaOTf (Sodium Triflate, NaCF3SO3, is an advanced electrolyte salt that is highly valued for its excellent stability and conductivity in high-performance sodium-ion batteries (SIBs). NaOTf salt has the following features:
(1) High Chemical Stability: NaOTf exhibits excellent chemical stability and is highly resistant to hydrolysis (reaction with water). Unlike NaPF6, which produces highly corrosive HF gas when it encounters trace moisture, NaOTf does not. This enhanced stability improves the shelf life and safety of the electrolyte.
(2) Solid-State and Polymer Electrolytes: NaOTf is frequently the salt of choice for Polymer Electrolyte Membranes (PEMs), such as those based on polyethylene oxide (PEO). Its structural compatibility and stability make it well-suited for these non-liquid battery systems.
