When used as the negative electrode in sodium-ion batteries, the prepared hard carbon material achieves a high specific capacity of 307 mAh g –1 at 0.1 A g –1, rate performance of 121 mAh g –1 at 10 A g –1, and almost negligible capacity decay after 5000 cycles at 1.0 A g –1.
Hard carbon material is a category of non-crystalline carbonaceous materials, which could merge as the most promising candidate for sodium-ion batteries anode materials . Compared with graphite, hard carbon has a disordered configuration of carbon atoms and cannot be graphitized even above 2500 °C.
