Abstract

A pair of novel reversible oxidation/reduction peaks at around 0.44V is discovered during the deep sodiation of NaTi2(PO4)3/C obtained by the pyro-synthetic approach. This novel low-voltage plateau doubles the charge/discharge capacity of NaTi2(PO4)3, thus turning it into a more promising anode for Na-ion batteries.
