Effects of raw materials on the structures of three dimensional graphene/amorphous carbon composites derived from biomass resources

摘要

Three-dimensional graphene/amorphous carbon composites have been successfully prepared by using biomass resources as raw materials via a simple method. Most macrostructures for biomass resources are maintained in the obtained three-dimensional graphene/amorphous carbon composites during the synthesis process, but the microstructures for them change significantly. The structure and composition of raw biomass materials significantly influence the amount of adsorbed Ni2+, which could affect the structure and composition for the graphene/amorphous carbon composites. The obtained composites were tested as anode materials for a lithium ion battery. Our results show that the structures for the graphene/amorphous carbon composites play important roles from their electrochemical properties.
