Overview

Details

This product is developed for advanced energy storage research, particularly in potassium-ion battery systems. Potassium bis(fluorosulfonyl)imide (KFSI) is a highly conductive and thermally stable salt that serves as an alternative electrolyte component to traditional potassium hexafluorophosphate. Its bulky fluorosulfonyl imide anion promotes weaker ion pairing and enhanced ionic conductivity in organic solvents, which is critical for improving rate capability and cycling stability in potassium-based electrochemical cells. Commonly used in electrolyte formulations for coin cells, pouch cells, and solid-state battery prototypes, KFSI is also relevant for supercapacitors and other ion-transfer devices. The product is available in multiple laboratory-scale quantities from 5 g to 1000 g, making it suitable for both preliminary screening and extended experimental series. As a high-purity reagent, it supports reproducible results in materials science and electrochemistry research.
