Facile Synthesis of Hard Carbon from Molecular-Cooperative-Assembly as Carbon and Nitrogen Co-sources for Sodium Ion Storage |
| 초록 |
Hard carbon is engaged a promising alternative to commercial graphite anode for sodium-ion batteries (SIBs) because of its low cost, relatively expanded interlayer distance. Herein, we developed nitrogen-containing hard carbon using molecular-cooperative-assembly between melamine and barbituric acid. 3D-spherical melamine-barbituric acid (MBA) complex was obtained by hydrogen bonding in DMSO as a solvent, and nitrogen content of its heating products (800~1000°C, under nitrogen flow) are easily controllable by differing heating temperature. As a result, MBA-900 exhibits 370 mAh/g at the constant current density of 250 mA/g after the 100th cycle. It is remarkably high value, considering poor electrical conductivity derived from high nitrogen content (16 wt.%). This high performance of sodium ion battery employing MBA-900 will be discussed through XRD, BET, GCPL, EIS. |
