Porous NaTi2(PO4)3@C nanocubes as improved anode for sodium-ion batteries

Porous NaTi2(PO4)3@C nanocubes are fabricated by solvothermal/coating methods with using oleic acid as the carbon source. When studied as sodium-ion battery anode at 0.01 ∼ 3 V, the NaTi2(PO4)3@C electrode delivers a high reserved capacity of 140 mAh g−1 at 1 A g−1 for 1000 times.
