Add-Ons
Ca(TFSI)2 {Calcium Bis(trifluoromethanesulfonyl)imide is an electrolyte salt that is primarily utilized in the development of Calcium-Ion Batteries (CIBs). The primary function of Ca(TFSI)2 is to serve as a conductive medium that allows the reversible transport of Ca2+ ions between the anode and the cathode during charging and discharging, as well as its features of high ionic conductivity, wide electrochemical window, and high quality of SEI Formation.
