Carbon Derived from Pine Needles as a Na(+)‐Storage Electrode Material in Dual‐Ion Batteries

Pine needles are used as the precursor material to prepare hard carbon. Scanning electron microscopy, X‐ray diffraction, and N(2) adsorption–desorption tests are carried out to characterize the surface, crystal, and pore structure of the material. The pine needle derived carbon (PNC) exhibits excell...

Sumario:Pine needles are used as the precursor material to prepare hard carbon. Scanning electron microscopy, X‐ray diffraction, and N(2) adsorption–desorption tests are carried out to characterize the surface, crystal, and pore structure of the material. The pine needle derived carbon (PNC) exhibits excellent Na‐ion storage ability. A dual‐ion battery of PNC/graphite using a Na(+)‐based organic electrolyte is constructed. The batteries display outstanding electrochemical performance: a superior energy density (200 Wh kg(−1) at 131 W kg(−1)), high cut‐off voltage (4.7 V), and outstanding cycling stability (87.2% retention after 1000 cycles). In addition, the separate responses of the cathode and anode are investigated.
