High-performance amorphous carbon–graphene nanocomposite anode for lithium-ion batteries

An amorphous carbon–graphene nanocomposite was prepared using glucose and graphene oxide as the precursors via a facile hydrothermal route and subsequent calcination. The amorphous carbon grown on the graphene plane prevents restacking of the resultant graphene nanolayers and maintains the structural stability of the nanocomposite during the discharge–charge process in lithium-ion batteries.
