Pyro-synthesis of a nanostructured NaTi2(PO4)3/C with a novel lower voltage plateau for rechargeable sodium-ion batteries.
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.
