Abstract Scope |
This study aims to provide a new platform for the fabrication of metal-carbon composites. Herein we show that the high density crosslinking of a polymer can be used to homogenously trap metal nanoparticles and other components. Carbon nitride is employed to act as a nitrogen dopant source and textural template for the final product. We have shown that this method provides an avenue for the tunable fabrication of nitrogen-rich porous composites. Composites with a variety of different nitrogen moieties and textural compositions were electrochemically analyzed using LIB based systems. Electrochemical and post-mortem analysis of these composite materials suggest the superior electrochemical performance can be attributed to the unique nitrogen-doped carbon framework, which is able to buffer the large volumetric expansion of the tin due to its disordered flexible nature whilst contributing to the overall capacity of the composite from its high degree of nitrogen doping (~11.9 at %). |
