Product Details
Potassium bis(fluorosulfonyl)imide (KFSI) is evaluated where potassium-ion researchers need strong salt dissociation, concentrated-electrolyte options, or different interphase chemistry from KPF6.
Technical Selection Guide
Potassium bis(fluorosulfonyl)imide (KFSI) is evaluated where potassium-ion researchers need strong salt dissociation, concentrated-electrolyte options, or different interphase chemistry from KPF6. It is relevant to graphite, hard carbon, potassium-metal, and low-temperature screening, but its practical value depends on corrosion, solvent coordination, and formation conditions.
KFSI is typically compared with KPF6 and KTFSI. Use matched molality and temperature-dependent conductivity alongside EIS and cycling rather than selecting by room-temperature conductivity alone.
Technical Profile
Potassium bis(fluorosulfonyl)imide (KFSI) is used or screened for next-generation electrolyte research, including sodium-ion, magnesium, potassium, and alternative-cation systems. It is suited to early-stage formulation screening where salt identity, water specification, and electrochemical compatibility guide down-selection.
