Graphene-sulfur nanocomposites for rechargeable lithium-sulfur battery electrodes
Patent
·
OSTI ID:1134454
Rechargeable lithium-sulfur batteries having a cathode that includes a graphene-sulfur nanocomposite can exhibit improved characteristics. The graphene-sulfur nanocomposite can be characterized by graphene sheets with particles of sulfur adsorbed to the graphene sheets. The sulfur particles have an average diameter less than 50 nm..
