1.0M KFSI in PC with 10% FEC Potassium Battery Electrolyte (JC-5)

This potassium electrolyte, formulated as 1.0 M KFSI in propylene carbonate with 10% FEC (designated JC-5), is developed for experimental and energy materials research, specifically targeting potassium-ion battery systems. The high-purity KFSI salt dissolved in PC solvent provides a stable conductive medium, while the addition of 10% fluoroethylene carbonate (FEC) serves as a film-forming additive to enhance electrode interfacial stability and cycling performance. This electrolyte is suitable for evaluating the electrochemical behavior of potassium-based anodes and cathodes in laboratory-scale coin cells or pouch cells. Available in a range of quantities from 50 g to 1000 g, it offers flexibility for both preliminary screening and extended research studies, making it a practical choice for researchers exploring advanced potassium electrolyte compositions.
