Calcium intercalation into layered fluorinated sodium iron phosphate

Journal Article · · Journal of Power Sources
Here, the energy density and cost of battery systems could be improved by moving to alternative battery chemistries such as Ca-ion. However, in order to switch chemistries many problems need to be solved including the identification of cathode materials with high energy density, and electrolytes that can plate and strip calcium metal. Herein, the feasibility and cycling performance of Ca2+ intercalation into a desodiated layered Na2FePO4F host is described. This is the first demonstration of Ca2+ intercalation into a polyanionic framework, which implies that other polyanionic framework materials may be active for Ca2+ intercalation. Although substantial effort is still needed to identify a high energy density cathode material, this study and others demonstrate the feasibility of Ca2+ intercalation into multiple materials making it more probable that such a cathode material can be found.
