Description: In the lithium ion battery industry -- which includes mobile phones, notebooks, hybrid electric vehicles, etc -- aluminium foil coated with graphite, carbon black, or carbon nanotubes is used as a positive electrode's electron collector. When coated with graphene, the aluminium foil has significantly improved electrical resistivity; aluminum foil coated with graphene is 4.5x10-6 O.cm, whereas foil coated with carbon black is 7x10-6 O.cm.Information provided by Matexcel |
