Coordination of Surface‐Induced Reaction and Intercalation: Toward a High‐Performance Carbon Anode for Sodium‐Ion Batteries

Oxygen‐rich carbon material is successfully fabricated from a porous carbon and evaluated as anode for sodium‐ion battery. With the strategy of optimal combination of fast surface redox reaction and reversible intercalation, the oxygen‐rich carbon anode exhibits a large reversible capacity (447 mAh...

Sumario:Oxygen‐rich carbon material is successfully fabricated from a porous carbon and evaluated as anode for sodium‐ion battery. With the strategy of optimal combination of fast surface redox reaction and reversible intercalation, the oxygen‐rich carbon anode exhibits a large reversible capacity (447 mAh g(−1) at 0.2 A g(−1)), high rate capability (172 mAh g(−1) at 20 A g(−1)), and excellent cycling stability.
