What is it about?
A new intercalation compound Li2VO2F with disordered rock salt structure enables up to about 1.8 Li+ storage (420 mAh g-1) at ~2.5V with a lattice volume change of only ~3%. A high capacity of 300 mAh g-1 at 1C rate is observed. At -10°C, Li2VO2F can deliver a reversible capacity of 280 mAh g-1 at ~2.4 V.
