A new low-voltage plateau of Na3V2(PO4)3as an anode for Na-ion batteries

A low-voltage plateau at ∼0.3 V is discovered for the deep sodiation of Na3V2(PO4)3 by combined computational and experimental studies. This new low-voltage plateau doubles the sodiation capacity of Na3V2(PO4)3, thus turning it into a promising anode for Na-ion batteries.
