Abstract
The present disclosure relates to blended cathode materials for use as a positive electrode material of a rechargeable electrochemical cell (or secondary cell) (such as a lithium-ion secondary battery) and also relates to a secondary battery including a cathode having the blended cathode materials. In particular, disclosed are blends of lithium vanadium fluorophosphate (LVPF) or a derivative thereof with one or more conventional cathode active materials in certain weight ratios thereof.
