Tuning N‑Species of Graphitic Carbon Nitride for High-Performance Anode in Sodium Ion Battery

Owing to low cost and high theoretical capacity, g-C3N4 is known as the potential anode in sodium ion battery. However, its poor electronic conductivity and structural stability hinder its actual performance. Here, a simple gel coating–calcination method is used to get a g-C3N4@carbon composite (CCN...

Description
Summary:Owing to low cost and high theoretical capacity, g-C3N4 is known as the potential anode in sodium ion battery. However, its poor electronic conductivity and structural stability hinder its actual performance. Here, a simple gel coating–calcination method is used to get a g-C3N4@carbon composite (CCN). Benefiting from the increased pyridinic-N content and electronic conductivity and the fluffy and porous structure, CCN shows a high discharge capacity of 250/183 mAh g–1 at 0.1/3 A g–1 and a long-term cycling performance with 180 mAh g–1 over 1600 cycles at 0.5 A g–1. Moreover, a CCN//Na3V2(PO4)3 full battery exhibits good cycling stability.
