Transforming kitchen bio-waste into N-rich carbon nanofibers through direct sintering method improves the performance of carbon materials in sodium ion battery energy storage field. The design of low-cost bio-waste carbon materials provides a new approach for developing high-performance anode materials.
The low initial Coulomb efficiency and low specific capacity have always been the bottleneck restricting the development of carbon materials in the large-scale field of sodium ion batteries (SIBs) energy storage. Furthermore, the enormous biomass resources are not used reasonably and are burned or buried as garbage. Here we use a simple direct sintering method to transform the kitchen bio-waste into N-rich carbon nanofibers. Among them, the N-rich carbon nanofibers heated at 1300 degrees C deliver the best electrochemical performances in the cycling stability, rate capability and capacity retention, documented by the high capacity retention of 301 mAh g(-1) at 0.1C rate after 100 cycles with initial coulomb efficiency of 80.0%. The design construct of building low-cost bio-waste carbon materials provides a new approach to develop high-performance anode materials for the SIBs and even other battery systems.
