Аннотация
Phosphorus-doped soft carbon was synthesized by a facile phosphoric acid-assisted route. It is found that the phosphorus-doped soft carbon used as lithium ion battery anode exhibits a high reversible capacity of 333.6 mA h g–1 with the first cycle coulombic efficiency of 87.0% at the current density of 30 mA g–1. When used as sodium ion battery anode, it also shows great storage performance, with a reversible capacity of 121.3 mA h g–1 with an initial coulombic efficiency of 65.0% at the current density of 10 mA g–1. Besides, good rate capability and stable cycling performance are also observed for both lithium and sodium ion batteries, indicating potential of their application in large-scale storage devices.
